Two Fender Twins would make a great keyboard setup with 4 x 12 speakers and 2 x 100 watt tube amplifiers. How were they modified?


There were actually three of these amps made, and I had two of them. A friend of mine, Gerard, who was the technician at the music store where I worked, did the custom work. He's one of those naturally gifted and talented people who just knows how to get the most out of gear. He's also a wicked Country guitar player...the best in my area for sure.

He swapped out the stock speakers (Jensen if I remember correctly) and put in two Celestion full range (12's). He then added two very small horn like tweeters in between the two main speakers, one at the top and one at the bottom.

He then made up a custom crossover so that the signals were split up, lows to the 12's and highs to the tweeters, kept the spring reverb and added a balanced line out (to go to PA). I don't know if he changed any tubes around.

They were quite loud and clean, but it was the warmth as well as the nice detail that made them so unique. They would sound awesome on electric/acoustic guitar, and they sounded incredible on the Rhodes in Stereo. The setup I used in the photo also sounded pretty nice as well.

For a while, I used them on a DX7IIFD digital FM synth and they warmed it right up, but still kept the edge. The DX had an incredible electric guitar patch that was programmed by one of the Yamaha clinicians at the time, and it really sounded splendid through those Twins as did the B-3 and electric piano patches.

He built the three (we nicknamed them "Tweeter Twins") and made no more afterwards, at least based on Fender amps. He also refused to give away any exact details about how he modded them. I believe they are all still working and being used to this day ( I sold mine to a guy that uses them with an old Roland E-70), unlike Gerard and I who are both now retired from the retail end of the business, anyway.

PS...Jeez, Nigel, they were HEAVY (and awkward). I wouldn't want to have to gig with them today.
