Ok so I've got a Boss GT-10 and I like how it sounds, I just dont like how my amp adds its own color into it as well. So my question is can I just get a speaker cabinet and plug my GT-10 directly into that?
U just need some kind of line out system. You can just plug it straight into a PA, but through a mixer-> PA you can.
No, you need something amplifying the signal. Get an amp with an effects loop and plug from the multi straight into the return jack, or just buy a power amp. I did that for a while with my ME-50 before I had a decent amp.
