Dude, I just picked one of these up about 4 days ago. I'm really liking it a lot. It ain't going to wow you with gain, but turn all 3 knobs wide open and it nails the Zep vibe really well. The feel of this amp is very intoxicating. She wants to pleasantly feed back at just the right moments. I tried the BE-OD in front of it and it sounds really cool, but only when you pull the BE-OD's gain back to about 9 o'clock at the max. This amp cleans up great when you roll back the volume. I have had my band mates take a listen and all concurred that it sounds so Zepplinesque, it's scary. Can it hang with a full band volume wise? Probably not unless everyone comes down a hair. Mic it up and you can do GNR, Zep, Foreigner, etc... and the tone is just very stunning. Go try one out man, they are very cool. Plug into input 1 that links both volume knobs. Dime both volumes and turn the tone knob up about 3/4. Do the rest in your guitar. Tremolo feature is very nice, not as intense as some similar amps, but sounds very cool. Oh, BTw, first one I took home had a bad power tube and was all scratchy/staticky sounding. I returned it for another new one and that one was fine. The power tubes in this amp are an unusual bird. About the size of EL 84's. Also, I pulled the chassis on the first thinking the prob was something other than tubes. It's all PCB inside, however the price point on the amp would make you think that it would be handwired.
Anyways, this is a super fun amp to have next to the couch to plug into and geek out with. Again, the tone is just cool as hell.
