Can anyone explain what is happening here, I'm using this patch http://line6.com/customtone/tone/208422/ It looks something like this: __ EQ__Amp A __ __EQ__Comp__EQ__ / Mixer \ __ EQ__Amp B __ Both amps are switched off. I have my guitar lead going into the 'Guitar in' and my output lead going out via the '1/4 out L mono'. I've changed Input 1 to Guitar as has been recommended, it was originally Guitar + Variax. Input 2 was originally 'Same' but I've read 'Variax' is recommended for a clean sound. When I'm scrolling through the input 2 options, I find that 'Guitar + Variax' gives it a very full sound and 'Variax' for input 2 sounds rather flat. Why is this? My guess is because there's no signal going to the lower 'Amp B' path, correct? There is also a loud hiss when I select 'mic' even though I have no mic plugged in, what's going on there? s
