Around 1998 I decided to buy an old beat up Fender Bassman Blackface head and see what I could do to learn and modify. It cost about $225.00 and I figured what’s the worst thing that could happen? I blow it up. I purchased about a dozen tube electronics books from the 1930’s to the 1960’s as well as modern electronics college level texts. I treated this educational undertaking with a passion, studying for hours every day. I have completed home study college level electronics courses with honors. I made many mods to the old Bassman head, always getting some friends to come over and verify I was in the right direction. After a year or so, some friends started asking me if I could mod their amps. I agreed and took a chance. After years of study and experiments I gained the confidence to proudly do mods, repairs and eventually do my own builds. I now have a large client base that extends from the 5 boroughs of New York City through Nassau and Suffolk County on Long Island, parts of New Jersey. I service professionals, semi professionals as well as week end warriors. I don’t claim to have reinvented the amplifier wheel. What I do best is borrow ideas from many different places, associate them together in to a new place of my own. I work alone, building 1-3 amps per week. I have developed my own system for consistency. Current production models are identical to each other in all details. The expertise that I have gained over the years in combination with my ear, allows me to take what people describe in words and turn it into amplifier reality.
