Oh what's this? Looks like we'll need something to open that up... No, not that. This will have to do Okay, some potential cfc's... Oh, what's this under here? Alright, enough messin around. Here ya go Damn that's an awful lot of glass And there's the wierd uncle way in the back.... Currently being used as a makeshift PA right now. The Story: For those that don't know, this is a peavey roadmaster, the main stage amp of Thurston Moore from Sonic Youth. Ever since hearing it's little brother, the rockmaster, at a show I've been on the lookout for one of these. Now, I'm NOT trying to imply that this particular head was owned by SY. However, in a wierd "twist of fate" I did purchase it from one of the founding guitarists of ... Mushroomhead. That being said, the amp was packed super well. The tubes we're removed, boxed up, and individually bubble wrapped and labeled with thier respective position. Dude shipped it super fast, and was incredibly friendly throughout the whole process. I actually found the amp through the Peavey cvlt Facebook group and we've exchanged quite a few messages about gear and other music related things. Safe to say he's a pretty cool dude and a breeze to do business with. The Sound: Just going off first impressions, this amp absolutely slays. Clean channel is clear and "glassy" with a middle or neck single coil. The built in reverb is decent enough. Just not very prominent (quick decay and not very loud). Possibly the tube driving the reverb is going out? The power amp is loaded up with some fresh sovteks, but a new set of preamp tubes probably wouldn't be a bad idea. Either way, I always get my reverb from a pedal, so I'm not worried about it at the moment. Now the lead channel? Oh my. Extremely gritty and aggressive. Lots of attack, and surprisingly defined for a vintage amp. And the gain has an interesting character I'm not used to, but really like. Every other amp I've owned has always just gotten fizzier the more gain you pile one, but it sounds like all the grit is somehow "concentrated" in the low mids, of that makes any sense. As a result, the more you turn up the gain, the more the amp just roars. I haven't had a ton of time to dial it in yet, but right off the bat the lead channel can cover everything from doom, sludge, stoner, hardcore, and wvereveryt in between. And if the lead channel doesn't cover it, then running my boss os-2 into the clean channel definitely does. Not to mention it has independent 3 band eq and independent thick and bright switches While waiting for the amp to arrive I studied over the manual to get a feel for how to dial it in, and the "gain block" on the lead channel is a pretty interesting, but also hard to understand feature. It's made up of 3 knobs: pre gain, pump, and post gain. According to the manual and my loose understanding of it, the pre gain knob determines the amount of gain at the input stage while the post gain determines how much signal reaches the power amp. That's all pretty standard. However, I'm not really sure what the pump knob actually does. Apparently it "changes the character/gain structure of the amp" and the effect of each knob will change relative to the positions of the other knobs.... All I can hear with my ears is that turning everything closer to 10 just adds more grit and volume, but I'm sure I'll notice more subtleties after spending more time with it. Tl;Dr: this thing is damn loud, and definitely worth the wait.
