Peavey Rockmaster

Is anyone familiar with the Peavey Rockmaster? (It's an older, rackmount, tube preamp.) If so, I'd appreciate whatever input you have. Thanks in advance.

i'm using one right now, i think it's great. i plugged into it at a used place knowing nothing about it. i was blown away. that combined with the price tag, i had to buy it. cleans, well they aren't so hot. maybe because i use high output pickups, but the clean channel distorts on me. the crunch channel compares to an AC/DC type sound. the Ultra channel is massive distortion, for leads or heavy riffs. the crunch and ultra share a 3 band eq. there are a bunch of fx loops on back, one for everything, one for ultra/crunch channels, and then one for each of the individual channels. 3 out's, one at 0 db, one at +3 db and an XLR freq. compensated lineout for mixers or recording. footswitch jack. seriously, for the price it's hard to beat it. i've read about guys getting them for $40. I paid $140 but i wasn't going to go searching around for the best deal, i wanted it then and there.

i've used these preamps for almost ten years. they can have great shimmery cleans [but the clean volume control is pre-gain and will distort with high output pickups] and they can have very articulate and thick saturated heavy crunch tones. they have 5 FX loops, one for each channel and two common ones, and the +3 dB output to slam the input of a tube power amp, for tremendous patching flexibility.

tweaking the shared active EQ on the gain channels is the trick, and some type of outboard EQ is almost mandantory. also you must have a 2 button stereo cabke footswitch to change the channels, there are no switches or lights on the preamp. the FX loops jacks will get scratchy and cause sputtering and/or a volume drop, so i hose mine down with contact cleaner every 6 months.

i run 7 strings into mine through Boogie 20/20 or 50/50 power amps and they sound great. check out or for sound clips of both my bands, prog/metal/fusion and hard rock respectively. all the recording used Rock Master preamps.

but especially for the rediculously low prices they often go for, these units a great bang for the buck. you can change the tone in really neat ways by swapping different gain varieties of tubes.

Excellent! I appreciate the feedback and I will check out the links when I get a minute. I've got a Mesa 50/50, too. Just think, I was considering the $700 Voodoo Lab (with no FX loop).
