Thanks for the add... I'm a retired electronics engineer and not much of a musician, but I love music + the art & science of sound. I cut my teeth with valve radios and amplifiers in 1970, at age 12 and find myself at home with boxes of valves & bits. Building two custom valve amps and valve fuzz/reverb for my son and niece, who are musically passionate and more gifted than me. I do have an old Epiphone guitar as part of my lab gear and for visitors to blast through ancien KT66's.
Lots of good info here on these forums and I can smell the passion.
