I also do strict “to the schematic” repair and restoration work for those who want their collectables to remain true to their vintage specs. If your amp does get a tone tweak, it will be with the above considerations in mind and can be put back to stock easily in the future if that desire should arise.

I don’t do “hole-drilling hack mods” for anyone – these old amps will be around long after most of us are gone, and any tweak made is done with respect for this. The wrong tweak in the wrong amp and problems happen – like oscillations at frequencies you can’t hear motor-boating, ghost notes etc.

Some amps give you more room to tweak than others and this is where experience really counts. The more details I can get from you, for instance, what type of music you play, what guitars you use, style of music, size of venue you normally play at, things you are looking for in an amp, and the things you are NOT looking for, the better I can tweak your amp to make it better suited for your needs. There are a lot of people today who do tube amp work – why send your amp to us? With 20 years of experience and not only an ear for what your tube amp should sound like and how it should perform, I also try to get to the core of what you are expecting from your amp. I also use several reconing services, including WeberVST and Neals Speaker Service to get your old tired stock speaker sounding the way it is supposed to if it’s required. I don’t recone speakers, or carry new replacements here, but can normally get them in quickly if needed. I use vintage correct parts whenever possible, and carry in stock: tubes, transformers, carbon comp resistors, tube sockets and most any part needed to get your amp in top shape and back to spec. I offer custom amp builds, using my own circuits or other public domain circuits on a customer request basis. So every amp that comes here for service, repair or tweaking is always “Guitar Tested” to make sure that it meets that standard. I have also been a guitar player for over 40 years and as a player who performs on a regular basis, I understand how amps perform in “Real World Gig Conditions” as opposed to just sounding good at lower volumes around the house. you name it and I’ve probably owned one, played one or had one on my bench for repair. Valco”), and I have been collecting, repairing and restoring tube amps for 26 years and have owned or repaired just about any amp you can think of including: Fender Tweed, Blackface and Silverface, nearly any Valco built amp ever made including National Dobro, Ampeg, Gibson, Guild, Hiwatt, Marshall, Sound City, Magnatone Silvertone Danelectro….
