I've been using the HX Stomp for a month or so now and am enjoying it- in particular have been using it into the FX Return on my small tube amp. Now I have a gig coming up and am not sure what to tell the venue for hookup requirements. We'll have access to a 4x12 cab, but can I go straight into that? Should I be asking to go into the FOR? I've never done that before and to be honest don't even know what to ask here. I'm not even sure i have my setup right for playing into my little amp at practice because I'm still fiddling with things every week.
