Powering up Takamine Cool Tube

Both my Takamine guitars (TF740FS and TC132SC) are equipped with Cool Tube® CTP2 preamp. If you play plugged in and want to save some money and time on battery replacement, this post is for you.

Disclaimer: I studied electronics many years ago but I am not an electronics engineer, so use this solution at your own risk. Moreover, it is not certified nor approved by Takamine in any way. I tested it in one configuration only as described in this article.

The DI-Plus and the CoolTube are perfect on-stage partners. Besides the D.I. and other functions, the DI-Plus serves as an external power supply for the CoolTube.blue moreinformation2 Powering up Takamine Cool Tube

The easiest (but not the cheapest) way to power up the CTP2 from the external power source is to use Takamine DI+. It’s a great device – I tested it! It  provides several essential DI functions, plus it works as an external power supply for CTP2. Its retail price is around $200. However, I didn’t need a DI and thought that $200 is too much for a power supply. So, I decided to find a less-than-$20 and easy DIY (Do-It-Yourself) solution.

DIY solution – the idea

I had DI+ at my disposal for a while and looked how it powers the CTP2. DI+ connects to the guitar via standard 1/4 TRS stereo cable, uses one wire for passing the signal and another one for powering CTP2 (+6.7 volts on the ring connector).

Here is what I realized:

  • CTP2 has a circuit for disconnecting the battery if there is some voltage on the external power connector (aka comparator)
  • An external power supply providing 6.7-7.5V should be ok. Probably even 9v (typical power supply for guitar pedals) will work just fine, but I didn’t want to grill my CTP2 and never tested it.
  • 0.5-1A current should be more than enough for CTP2
  • I did not want to change anything within the guitar (wiring, connectors etc)

The picture below shows the idea:

Connectors

I found an inexpensive ($6) and compact Y-adapter Hosa YPP-491. It takes mono signals from two 1/4″ TS connectors to stereo TRS female connector. This is how all parts are connected:

RadioShack 273-1761 Linear Power Adapter

The modern transformer-less lightweight power supplies are SWITCHING power supplies and are very noisy for audio applications. Don’t repeat my mistake – they WILL NOT work well in this solution.

Instead, I went to the nearest electronic recycling store and picked a relatively bulky used 6V/800mA RadioShack 273-1761 LINEAR wall wart for five dollars.

Then I simply cut the old connector from the power supply, found ‘+’ and ‘-’ wires, and soldered them to the 1/4″ TS connector. The ‘+’ wire goes to the Tip and the ‘-’ wire – to the Sleeve terminal on a 1/4″ TS connector.

The result is: it works just fine! I even recorded it via my audio interface and compared the level of noise with battery and external power – it was the same, no differences.

This project cost me about $20 with all connectors and about 6-8 hours of fun. But please take into attention the disclaimer from the beginning of this post icon smile Powering up Takamine Cool Tube

Takamine TC132SC Review

This Takamine TC132SC Review explains my impressions and experience from 2+ years of playing this guitar, why I chose it and what I did to fit it into my style. From one side, TC132SC is a classical nylon-string guitar with standard 2″-wide neck and neck and body joint on 12th fret. From the other side, it has all attributes of the modern guitar: cutaway and electronics. But let’s start from the question why I chose TC132SC.

TC132SC, TH-5C, TH-90

TC132SCvsTH5C 208x300 Takamine TC132SC Review

TC132SC (left) vs. TH5C (right)

Here is what I looked for in a classical guitar: deep, warm and mellow sound for playing classical ‘nylon’ jazz and accompanying to the singers.I looked for the cedar top, and ‘dark’ back and sides – in general, they produce warmer sound (IMHO). I wanted a convenient classical 2″/52mm-wide neck, good playability, low action, and high end electronics. I looked for a guitar from a manufacturer with good reputation. I even bough a guitar from another Japanese manufacturer but didn’t like it and return it. Takamine’s Palathetic pickup and CoolTube CTP2 preamp made the difference.

I liked reviews of Takamine guitars on YouTube and informal reviews on the forums. Three classical Takamine models TC132SC, TH-5C, and TH-90 looked good for me. TH-90 was out of my price range, so I focused on the first two.

TC-132SC has solid cedar top, solid rosewood back, and laminated rosewood sides. The key difference of TH-5C was solid rosewood sides. Retail prices on TH-5C were about $400 higher. I talked to an owner of both guitars, a professional flamenco player, how significant is the difference in sound. He replied that he didn’t hear any difference in sound between them. I didn’t care too much about the exterior, and went with less expensive model.

Local music shops in my area didn’t have any TC132SC in stock, so I couldn’t try it. I talked to a few Tak owners at Acoustic Guitar Forum. All of them were very positive about their experience. So, I liked how it sounded, I liked the feature set, the most of the formal and informal reviews were positive. It was a Christmas sales season, and I bought it new online with a good discount.

First Impressions

Right after unpacking it, my first impressions were … well, they were “mixed”. Guitar’s playability was great, action was almost right (low enough for me), but it didn’t sound as I expected. Not rich, not warm, not deep. Duck will be the right word to describe the sound after I tried this guitar right out of the box. Note that it was winter time, and TC132SC was shipped to me from opposite side of the country.

However, I’ve seen cases like that with new guitars before, and I was prepared. I installed my favorite high-tension  strings, inserted a Planet Waves guitar humidifier to compensate for the winter’s low RH, let it settle down for one day and postponed all further tests until later.  And the next day it sounded acoustically … just as I expected! It sounded much richer, brigh and deep enough. I like to hear a balance between the punchy sound of the high strings and solid mellow bass line – and I heard it at that day and thereafter.

Guitar Setup: Rounds #1 and #2

I wanted to tweak the setup a bit, so I brought it to a guitar tech and asked for a few things:

  • lower the action (sand down a saddle just a bit)
  • add two extra side dots at 15th and 17th frets
  • add a strap button
  • polish the edges of the nut – they were too sharp

It took two rounds for guitar tech to make it right. I wasn’t very satisfied how action was setup – the low strings still buzzed. At that time those issues weren’t critical for me, and having two concert rehearsals per week, I decided to put any gear improvements on hold for a while.

I played this guitar a lot for the next several months, and got many compliments from the listeners. With my friends, we did a small house concert as vocal, bass and guitar trio. It went very well, and I played both via pickup/preamp and via an external dynamic microphone. I was fully satisfied with the results but …. wanted to try one more thing to make sure it’s not just a good guitar, but an exceptional guitar.

Round #3. To PLEK or not to PLEK

plek pro p3 270x280px Takamine TC132SC Review

PLEK Pro Machine

Several months later, I’ve got time and money to take the next significant step. I think most TC132SC owners won’t need to do that, but my perfectionism didn’t let me to ignore it anymore.I wanted to do two extra things with my Tak:

  • Further improve playability
  • Add an internal microphone

To address the first thing, I decided to run my guitar through the PLEK service. You can find more information about PLEK on this site. Shortly speaking, PLEK is a computerized machine that does high precision guitar fretting job.

Muke Lull’s guitar shop in Bellevue, WA has a PLEK machine. Actually, I already tested it with my gypsy jazz Saga Gitane D500 guitar a few years before and was very impressed by the results. It improved the guitar’s playability significantly. So, I went there for the second time and asked Mike to PLEK my TC132SC.

PLEK did a VERY, VERY good job on frets leveling, crowning, and polishing. My fingers literally can fly over the fretboard and I am more than happy with that!

Takamine TC132SC Review. A year later

One year later, I am still a very satisfied player of TC132SC.  In addition to the improvements described above, I shaved a little bit more off the saddle, got the excellent playability and some light string buzz. What I want to do next is to order a couple more bridges adding 1mm and 2mm to the action. Probably I’ll do this later this year.

Here is my clip on YouTube where I play a Russian Christmas Song. You can hear how my guitar sounds (after a couple of minor tweaks in DAW)

I also tested different strings and settled down on one particular kind – Savarez 540CJ high-tension strings.

I found that my TC132SC has GOTOH 1:14 tuners 35G420. They work well, and I lubricated them recently to make the tuning process smooth.

Takamine TC132SC Review. Two years later.

Two year later, I have nothing to complain about. I play for TC132SC and TF740FS in 50/50 proportion, both plugged in and non-amplified, and am still a very satisfied player. I didn’t do anything else with the guitar, even didn’t touch the action, but still feel that I need to raise it just a little bit. Will see how it goes icon smile Takamine TC132SC Review

Conclusion

My friends asked me “Why Takamine? Why not Taylor, Why not Cordoba, why not Ramirez or something else?”. My answer was “Because of good acoustic sound, quality, playability, Cool Tube and a good price”.  I experimented with external EQ and preamp (D-TAR Equinix and Solstice) and was able to find “my” sound both acoustically and through electronics.

I should also admit that I am not the most rational guitar buyer in the world. Resale value of a guitar with laminated sides (even with the solid top) is not very good. But I don’t change guitars every year, this one should work for me at least for 4-5 years, and who knows what happens then. I am glad I bought it, PLEKed it, and I like playing it very much.

Michael Markure is Takamine’s ambassador for acoustic guitar community and business. I like his reviews. He is a very knowledgeable guy – you can often see his exhaustive answers to the members on Takamine forum.

Another good demo of TC132SC by Chafinmusicenter

This video is a fast capture ‘on the fly’. The sound in the beginning is thin – probably because of camera is too far from the player and the camera’s microphone is not too sensitive (or gain is low). To my taste, TC132SC with those strings sounds too sharp – almost like a steel string guitar. But, again, it might be caused by bad audio recording.

Singer and guitar player Roman Lankin

Roman is my favorite singer, guitar player, music arranger and performer. He plays TC132SC for many years. His Takamine is several years old and has CoolTube CTP1. Roman also added an internal microphone and mixes it with the pickup. It sounds excellent – I heard it many times. On the video below he plays and sings the old russian song ‘The Drummer’.

Below is one more Roman’s video – there he uses his classical Takamine in a very non-classical style:

Fantasia (S. L. Weiss) performed by ThinkingDog

I like clear acoustic sound on this clip. It’s punchy and has a good balance between lows and highs.

Duet in D from the user lemintrepid

Looks like he recorded directly from the Takamine’s pickup. Very nice melody and arrangement. Looks like it was recorded direct from TC132SC pickup and preamp into audio interface. To my taste, it has too much reverb, but it still sounds good!

Enjoy!

Takamine TF740FS Review

tf740fs thumb Takamine TF740FS ReviewThis post is the second episode in the short series about my acoustic guitars.
You can find the previous one here:
About my nylon string acoustic guitar: Takamine TC132SC

Intro

I’ve been playing Gypsy Jazz (GJ) rhythm guitar for about five years. To make a long story short, I liked GJ style, but I loved fingerstyle more. It was hard for me to find enough time for both styles, and I wanted to focus on one. My Saga Gitane D500 was an excellent guitar for Gypsy Jazz, but … I wanted to play fingerstyle, so I sold D500 to a good guy from Portland, OR. (Thanks Jesse!)

Not so long before that, I went to the shopping tour around the local music shops and played 20-30 different guitars. I found a Walnut Taylor 416CE-LTD, 2011 Spring Edition and I liked it. People at Bellevue American Music were so friendly and helpful, but … price was too high for me and I dropped that idea.

Verse

Being a satisfied Takamine TC132SC owner, I looked at Takamine too. I found some very good (but rare) reviews of Takamine TF740FS acoustic-electric guitar. With 1 7/8” (47.5mm) neck width at nut, 12th fret neck-to-body connection, short scale, solid cedar top and mahogany back and sides, it was positioned as an acoustic guitar for fingerstyle. As with TC132SC a year ago, I didn’t find any TF740FS locally, but I talked to people on the TakamineForum.com and Acoustic Guitar Forum, watched videos on YouTube and read everything about this guitar.

I liked what I found. One of the TF740FS owners told me that his guitar not just sounded well, but had a  good setup and low action right out from the factory. Another player was excited by guitar’s high accuracy in intonation, but wasn’t very excited by how it looked. Ok, it’s fair, but I don’t like too bright inlays or too advanced ornaments, bells and whistles on my guitar. I prefer plain wood on the top and side dots on the side of neck.

Finally, I noticed a used 1-year old Tak TF740FS on eBay, sent a few questions to the top-rated seller, was satisfied with the answers and bought it.

Chorus

It arrived a week later and was in “like new” shape. Thanks Phil!  My first impression was “Wow! That’s THE sustain!” The sound was endless! The body was deeper than a standard OM model, so it sounded much fuller than a typical OM-sized guitar. It had Elixir Polyweb light strings on it. Very warm mellow tone with a deep sounded bass. Wow!

I thought that the guitar was already PLEK-ed (or, at least, half-PLEK-ed) at the factory. The action was right, and the intonation was very good. My only wish was to have frets polished a bit better. But it was a used guitar, and it’s a good reason to visit a guitar tech. It sounded great, I felt it very well and it was MY guitar! I put a TC132SC aside and played TF740FS only for a couple of weeks. I put on new extra-light phosphor-bronze strings, but didn’t like them and will replace them with something “heavier” soon.

Solo

These days I play TF740FS just for a few hours a week, and play TC132SC much more. I am working on a few nice Russian romances and found that they sound better on a nylon string guitar. When I finish that, I’ll switch back to the steel strings. I’ve got the impression that a good steel string acoustic guitar is faster and easier to play. It’s very subjective and it all depends on who, what and how one plays it. My fingers feel much less resistance on steel strings and fly all over the fretboard much easier. It’s hard for me to explain all the details of that feeling, but I hope that my fellow guitarists understand me. D500 was such a guitar for me (I invested into D500′s playability A LOT), and I want to brush up TF740FS a little bit more too.  Anyways, I want to record Moon River, Tenderly and some other beautiful melodies on TF740FS. Keep tuned icon smile Takamine TF740FS Review

Outro

P.S. TF740FS has a Takamine Palathetic pickup and a CoolTube CTP2 preamp installed. I am not a big fan of the electric piezo sound, even softened by a tube preamp. I play plugged in from time to time and I found how to deal with it. It’s a different (and expensive) topic and eventually I’ll write an individual story about that too.

P.P.S. Now I have two brown Takamine guitar cases staying side by side. TF740’s case, though, is muuuuch thicker than TC132SC’s one.

Isn’t she beautiful?

I love this cedar-top guitar! Mahogany back and ebony threaded headstock look great too. The simple round fret dots, elegant rosette inlay and natural wood work best for me – I am all for such simplicity!

A comment about the cases.

Takamine provides high-quality guitar cases with their guitar. On the picture with guitar cases, one on the left is for nylon-string Takamine TC132SC, and another one on the right is for steel string Takamine TF740FS. TF740FS is positioned as a guitar for fingerstyle. Its deep body helps to produce solid deep sound. Due to that, the case for TF740FS is wide too and it also has an extra latch on the opposite side. Other than that, both cases are the same inside and outside, and both are high-quality guitar cases from Takamine.
