“Dave T:- Thanks again for an exemplary job in repairing my Gallien Krueger ML/E-206, hopefully giving it another 25+ years of service. Despite the unavailability of original parts, you took the time to investigate replacements...”

Shaun S: "Marshall JVM205: YOU'RE THE BEST!!!! thank you so so so so so so much!!!"

MM: "... hooked up the Marantz amps. 'Astounding!'; Is my best description of how they sound. Many thanks for doing great work."

JB-"Played around with the amp for a while tonight, and I'm nothing short of amazed! It's like the amp's been asleep since I've owned it until tonight!"

DM-"Wow, that's incredible!" "A job well-done! All of the noise(s) have disappeared and the audio quality has noticeably improved. Again, thank you for doing a great job, at a price I could afford."

AD-"Thanks again for your work on the Super Reverb. I'm really happy with the way it sounds now."

JB-"All in all, I couldn't have asked for more, especially considering the cost! Thanks very much for making an old guitar player extremely happy!"

WG-"If you can picture a harp player smiling while he's playing harp , then that was me. Thanks again."

Dave M-"NO MORE INTERFERENCE SOUNDS! You're the greatest! I can't thank you enough!

A Very Unusual Repair Project

Nick Rhodes created just one Fender Pixelator Guitar that was conceived for a charity auction.

This was bought by a collector and sadly when he got it back home it had stopped working. He took it to us for repair. We found that the internal processor and software had been zapped by static electricity and destroyed. We had to recreate the control software form scratch as the original designer, who we managed to track down, no longer had that information.
