Mesa V-Twin problem

[Shane]

Hi Folks
I have a Mesa V-Twin in thats got a problem.
There seems no difference between the Blues and Solo sounds. I suspect some switching issue. Rest of it seems OK.

It would be real helpful if I had an accurate schematic, the ones around are totally innaccurate as far as component numbering goes. Finding my way about this PCB is hard enough without a map!!
Anyone out there got a true one?

Also what should the switch under the plate on the bottom of the unit labelled 'blues to solo' do? it seems to do nothing at present, Maybe thats part of the problem.

Any suggestions or a decent schem would be appreciated.
Cheers
Shane

do you have the V-Twin pedal or the rack mount version?

[Shane]

Hi Tim
Its the pedal

[tim]

here's the schematic I have for the pedal...is this what you need?

[Shane]

Most excellent! thanks Tim!!
Now I gotta figure out whats wrong with it and what that blues-solo switch is supposed to do!

Shane, I'm going to post the one for the rack mount version too, only because it has a block diagram, invaluable in diagnosing switching problems in M/B amps. Not sure if it will be of any help but it might be close enough to the pedal for you to figure out what they're doing....

Good luck

Thanks Mate
I'll check it out.
