Welcome fellow tone fanatics.

I have a mission:
That mission is to get your equipment to perform at it's most optimum ability, which in turn inspires great music for all!Being an honors graduate of Guitar Institute in Los Angeles, Ca, I am serious about great guitar tone. I have been playing guitar professionally for about 25 years, including a 3-year stint with Nashville A-list singer/songwriter Bobby Pinson
I have a great passion for squeezing good tone out of tube amps, and troubleshooting all things audio.
I have always tinkered with my own equipment doing simple repairs. But after giving huge amounts of $$$ to supposed amp gurus that did nothing but destroy my tone, I decided to get a degree in electronics from SJCC's excellent program.
Now, after 15 years of electronics repair experience, and persuing the holy grail of guitar tone, I can use this knowledge to tailor your equipment to the sound you desire.
Peace,
Stan
