Want OD/Distortion. I play an active jazz w/3-band onboard pre into 300 tube watts & a 210/212. I play, mainly, 60's-mid 80's rock. I really think I want a tube OD/Dist box to go w/my tube amp & the ones I'm considering strongest are the EHX English Muff'n(maybe Hot Tubes, & how different are these really?) or a Maxon 881. What do you guys think? Other strong tube choices? I guess one more thing, is there any real reason to go w/a non-tube OD/Dist other than the price on most non-tube units is (maybe) lower? Appreciate any/all comments.
