Who am I? I have been repairing tube and solid-state musical instrument amplifiers and P.A. equipment since the mid 70's. Working with local bands, as you can guess, I have heard and repaired just about everything. This gives me a unique perspective on sound, tone, and power used in the industry. Every musician chooses their equipment to express their own unique personality, and with my care we can preserve and restore that quality. - Andrew Cramer
