Wondering how much switching between fixed and cathode bias makes in a Fender amp? Do you know of any examples on YouTube?
Kind of my (limited) experience as well with Tweed and a few BF type amps that I've had a fixed/biased switch on. Cathode bias can more easily "sag", especially with a tube rectifier, sooner than fixed with a rectifier.In my experience with BF-Fender based Carr Slant 6V, which can switch from one to the other (or both) - cathode-bias has more harmonic complexity, fixed-bias is a tad louder, with tighter lows, and more fundamental tone.
p.s. Cool demo Leon!
