tonebender mkII professional - voltage on Q3 increased with breath!! :)

[ulysses]

hey guys

ive just done a new vero of the TB MKII PRO using transistors from smallbear

its cold here today.. about 10 degrees celsius

i was measuring up the voltages across Q3 and was wondering why it was measuring 3.72v on the collector..

i noticed that every time i breathed it would go up a couple of mV.

about 15 hot breaths later it was up to 4.5v

i heard that they were temp sensitive - but i didnt think this much - that would make a big difference to the sound

cheers
