saved my toneless SWR 750x head with a sansamp DI. currently i'm setting everything on my head at noon. i'm going into the head's active input, and setting sansamp flat (at noon) besides the drive all the way up...perhaps the treble and prescence are down just a hair. it is sooooooooooo bassy! i feel like the speakers in my Eden 410XLT are going to rupture!! what gives? i don't think my eqing is ridiculous, adn the volume is loud by not maximum - the heads only running at 400 watts with the 8ohm cab, was the swr just that bad? is the sansamp just that awesome? should i be setting the amp's tone controls, at least bass, at zero? is there another way to bypass the tone conrols on the amp? through the effects loop or something? thanks!
