I will get to the details in a minute, but I want to start by saying this is the amp I always wanted. It seems this amp can do anything. Has a great clean sound. Has that musically gainy sound like Page. And those kickass Marshall Plexi tones we've all come to love, as well as completely nailing the brown sound. So far I played it with a little slap back delay and nothing but a cord. I don't use the delay much. I've never had an amp that was so responsive that I didn't need any effects, reverb included. Because with my Les Paul, I can get limitless sustain. Even at low volume. But man, that classic Plexi sound I love so much and I never realized how it actually makes playing the guitar so much easier because the amp is so dynamic. So enough about that. Here's how it happened. In 1983 I bought a new Marshall JCM800 2205 50 watt Marshall amp with a 1960A cabinet. It was a great amp and over the years I had a few upgrades done to it. But over the last few years I started hearing a high pitched almost whistling sound coming out it. Eventually it just stopped working. So I sent it to David Bray Amps, who had modded my amp before, to see if he could fix it. Once he got the amp, he let me know he had it. About a week later we talked on the phone. He told me he could fix my amp, but it would cost more than to buy one of his new amps. He said my amp was made with the pots built right into the circuit board, and many other parts were just worn out and old. He could replace them all, but it would be labor intensive and would not be very wise of me. He said he was sorry he didn't have better news. I thanked him and told him I'd get back to him. At this point I really didn't know what to do. I didn't really want to pay shipping to get the amp back if it were not fixable, but it still had good parts like the box, the reverb box, the transformers, etc. But was it really worth it or was it just going to take up space? But then I got another call from Dave. He said he could fix my amp, but not in the sense I was thinking. He said he would gut my amp, put in a Bray Hand Wired circuit board, new pots, and I would basically have a Bray 4550 minus the tube rectifier. He said it would cost me $1000, plus the cost of tubes, and new filters if I needed them. He would re-use my Marshall Transformers, but after that it would be like a Hand wired 68 Plexi voiced by Dave Bray. While I would likely never have been able to afford a new Bray 4550, I was able ot afford to have my amp modded into something similar. I now I have this amp that is the amp I always wanted. It's been a long time since I have played this much and had so much fun playing. It's really re-newed my interest in playing again.
