Using Pedal Switcher or GCX as an A/B switch

Post by stoneboy26 » Wed Jul 01, 2009 5:25 pm

Hey - is there anyway to use either of the above as an AB switch to change between 2 instruments?

eg. 1 guitar/bass running into input of loop 1 on gcx and 2nd guit/bass running into the return of loop1, so switching loop 1 on or off selects between the 2?

Same idea for pedal switcher...

??


Thanks

This can be done, however as the Return jack is Ground Lifted you will have to somehow re-establish the ground connection. This can be done inside the switcher or by connecting the sleeves of the two incoming instrument cables together.

Thanks John - that would explain the noise I get then!! Thought it was a ground issue of some sort. I noticed if I run it through another pedal and into the return jack I am alright, which must be doing good things with the grounds - but not really practical.

I am quite happy at the moment just muting and switching basses so might save doing any work to the unit itself for the time being.
