Interesting comments! I have noticed the
same thing with my Fender Tone-Master that
your friend has. Certain amps, it seems,
sound much fuller and harmonically complex
after being played fairly hard for about
20-30 minutes. I experienced this phenomenon
when I tried out the Tone-Master in the music
store. I CLEARLY hear the same thing happen
at every rehearsal/gig with my band. The amp
seems to just blossom after the chassis gets
almost too hot to touch. CHECK THIS OUT! I was
browsing not long ago in a music store and I
happened to stumble across an Owner's Manual
for one of the Matchless amps that were on
display. Guess what? It stated in black and
white that their amps sound much better after
getting hot (which required about 20 minutes
of playing). No kidding!
There's some other (circumstantial) evidence
for this phenomenon. On the back of my Tone-
Master, there's a statement that reads
"CAUTION: Amp chassis gets very hot!"
Why wouldn't Fender just put in a fan to cool
this thing down and/or lower the bias on the
tubes and/or redesign the cabinet to allow more
air flow? I suspect it's because they've
noticed the same phenomenon.
In fact, I have been trying, without much
luck so far, to contact Bruce Zinky (the
designer of the Tone-Master) to find out what
his design intent was regarding heat
accumulation and tube biasing. Any advice
would be truly appreciated. Thanks.
