Well any pedal board is no replacment for a good amp in my opinion.That said,there are many who use the GT-8 as the main component of their rig by hooking up to powerd speakers(like JBL eons or something)and report great sound that way.I can't imagine the GT-8 sounding its best when run into the front of an amp.Definitley use whatever board or unit you get in the fx loop of the amp.

The funny thing is,BOSS actually has the suckiest support,manuals e.c.t.They make the product,but its third partys and communitys like bossgtcentral.com that push the product to its potential.
