I have seen many mosts with people using a Svt3 and SansAmp together but not how they have it hooked up. I got a RBI about two weeks ago and I am using it as a driver through the effects loop on my ampeg and leave it on all the time...is this bad??? I do have the settings set on a "neutral ground" (same volume whether the sansamp is on or off) so one is not driving the other. The reason I ask is because when I first hooked it up it sounded AMAZING!! We just played 2 gigs this weekend ( I dont over crank for gigs) and at practice last light my tone was just....something is def. wrong. I think I might need new tubes, Ive had the head for about 3 years so they're probably due. Is it a coincedence or could the SansAmp caused something to fry?? Thanks in advance!
