Re: Who has that Peavey xxx?
Well I don't play anything close to nu-metal and I like it so don't let that scare you off. The stock power tubes were less then satisfactory which could have contributed to Willie's comments but I don't think this amp's clean sound is going to sell many folks on it. Gain is it its strong point for sure. I run at low to mid gain settings and I am very happy with the sound. I switched it over to EL34 power tubes (Svet Winged C) and I got a lot more crunch of it which I like a lot, I imagine I go for a hotter AC/DC sound if you need a ballpark.
With single coils the clean is fine, I run a bit of delay and 'verb and I am covered but I wouldn't call them strong cleans. With humbuckers I don't really go to crazy for the cleans a bit too dark, the bottom end doesn't do it for me. I imagine a good set of 6L6's would be better suited to someone needing better cleans out of the amp. A good tube in V1 with a lot of clean overhead would help too. Still don't have the perfect one in there yet but again I run a hotter sound 99% of the time with this badboy.
The Crunch channel is where I have most of the fun. A really wide range of tones from a very raw Marshall-y sound to Recto type sounds. It has it's own voice though, the EQ has a huge range, being active you can get carried away but it is all pretty useable to me. I run the 2x12 combo so I lose some bottom but the EQ makes up for it. I run a closed 2x12 with it a lot of times and I can pummel you with this thing pushing 4 - 12" speakers, lots of punch with the closed/open tandem.
I run the Ultra channel a bit hotter and louder and kick it in for leads and such, works real well. Other than the fact that it is a heavy amp the combo is great. I'd consider running the head and a 4x12 cab as well only there is no reverb that way. If big gain is what you are after though you won't be running much reverb anyway.
