So this is probably a silly question, but is the EQ section of the F-1X "bass specific", or is it equally suitable for both guitar and bass?

Works just as well for guitar

Sure does, and has an effects loop on the back panel. (if you use such things...)

Much appreciated! Was thinking that was that might be the case.

I've been using mine for bass and baritone, but for some reason hadn't bothered to use it with guitar.
