Tech Corner: Changing a Preamp

Takamine guitar technician Joe is here to show you how to change out a preamplifier in your Takamine guitar. This is very helpful knowledge to undertake a task like upgrading your Takamine to a CTP-3 Cool Tube preamp, as Joe demonstrates here. Let us know what you think in the comments area below!

Does the tube ever need replacement?  What are the symptoms of tube failure?

Could I put a CT4B on my GN20CE-N instead of using the standard  TP-4TD?

D K.

Wow. This is cool. How do I get an upgraded pre-amp for my P1JC-12 (I think it has a CT4B II)? Are the upgrades sold in Canada?

 

Thank you.

Oh I figured it out.....the inscriptions are actually all printed on a thick foil plate which you can just peel up to reveal the clamp release hole underneath.

I Have a EGS330SC and I guess the same problem like you had. How you solved it exactely to get access to the hole underneath?

Thanks Marcel

I seem to have a very old pickup from the 90s and there isn't a hole to insert the tool into to access the other clamp. Do you have instructions to get this out?

I have the same problem. I have a EN12c - 12 with a Graph-Ex preamp. I would like to change it to the CTP-3, but don´t know, how to get the Graph-Ex out. Do you have some instructions for me too. Are there some more modifications needed to built the CTP - 3 in? Thanks

Same problem here. Have tried reaching in via sound hole, but can't locate the clip on my PSF-45C with AccurAcoustic eq.

Can anyone advise how to remove this please.
