Mods and Mod Kits for the Fender 65’ Twin Reverb

The Fender RI 65’ Twin Reverb has been around for a long time now and is an amp that is generally reliable and has a big clean tone. Unfortunately, it’s a lot more sterile sounding than the original it is based on. That’s were these mods come in. The upgrade some critical components and tweak the circuitry to give it a close very close to a prized 60’s Twin. We’ve been doing these types of upgrades to the Blackface RI amps for many years, and they always get rave reviews.

I offer DIY kits that you or your local tech can install. I also offer a couple of different speaker upgrades. The stock Jensen C12K is really a good speaker once it has broken in but it’s a bit more modern sounding and very heavy. We offer a light neo mag Lil’ Texas speaker set that has great 60’s American tone weighs less 10.8 lbs than the stock speaker set! For folks who want the sound of the JBLs some Twins came with we offer a Weber Alnico California set.


What we do:

  • Upgrade the electrolytic capacitors to F&T and ultra long life radials.

  • Tweak the circuit in few key places for better sound, touch sensitivity, richer harmonics.

  • Increase the reliability of the power tubes while increasing touch sensitivity.

  • Replace the Output Transformer for Hammond which is built vintage correct.

“Hi Carl,

I wanted to let you know i am really pleased with the kit you sold me. The soldering was fairly easy and straight forward.

I bought the hammond ot locally and retubed with tung sols power tubes and a combination of new and nos tubes in the preamp.

Also changed the stock speakers to Jensen Alnico’s.

The amp made a huge improvement. It really came alive. I almost cannot beleive its the same amp. 

Thanks again for the kit and the knowledge!

Greetings,

Dennis”
