I'm experimenting with a cross-line master volume (Type 3 of the Train Wreck pages) on a Fender Bandmaster, and something sure ain't right!
Here's what I did:
I used a 1M audio double pot (it's all I have handy) and just used the back 3 lugs.
From the FRONT of the amp, numbering the pot logs from LEFT to RIGHT, 1-2-3: Center lug (wiper) to the right-most 220k resistor (closest to the bias pot) and lug #3 to the leftmost 220k resistor. Lug #1 is not connected.
The master seems to jump in volume and become VERY LOUD almost immediately, say on a setting of about 2. Also quite noisy.
What have I done wrong here? It's sure not acting like a master volume! HELP!
Thanks,
Fred G.
