Takamine Service & Repair Forum

This preamp was missing a pickup that plugged in behind the preamp with a RCA jack. It did however contain with it a 1/8th inch male to 1/4 inch female pigtail for the guitars input. I was curious as to where I might be able to find a wiring diagram for this and another Takamine Pre-amp I am currently working on. Its a Graph-EQ Pre-amp. It has a battery with an LED switch for batt check, a volume control, three band graphic equalizer and an extra fourth slider called an exciter. The other has in place of the exciter a volume gain slider and no knob at all. It seems as though the two units are not working correctly and I believe that it is due to somebody working on them prior to my obtaining them who didn\'t know what they were doing. A diagram is a must in this situation and any help would be greatly appreciated. Thank you.

I have a 2001 graph ex pre-amp and recently the volume pot has been giving me problems. I\'ve tried cleaning it but it is so sealed up that it is hard to get any spray in there. I even drilled a small hole in the plastic housing and got the same result.

I\'ve tried cleaning it but it is so sealed up that it is hard to get any spray in there. I even drilled a small hole in the plastic housing and got the same result. I think if I replace it, my problem will be solved. I hate to spend $200+ for an entire replacement, when I can just solder on a new knob. Any suggestions would be appreciated.Thanks

I am not receiving low end power when plugged into my amp. I get plenty of highs and after talking to someone from Tak they suggested it being the preamp assembly. So, I am looking for a replacement pickup assembly for my Tak fp360sc. If you have these in stock could you please send me a price.—> …Purchase or Repair: ...I am not receiving low end power when plugged into my amp.
