I thought I'd never own another Peavey guitar amp. The first two amps I owned, 37 years ago, were Peavey. And they were terrible sounding. FFWD to yesterday. I traded my "spare" Rivera Duo Twelve for a 5150("script" version). After having it for 24 hours and playing through it with my cabs and different guitars, I've gotta say I'm impressed.(I haven't used an OD pedal yet..., so I'll update that in a day or two) Everyone knows the gain channel is a beast.(true dat!) But, on top of the raging distortion, I really like how "quick" the attack is on single notes. (With the pre-amp gain between 4 and 5) The 5150 is not, to my ears, a Marshall wannabe. It has its own thing going on. I'm really looking forward to using the 5150 in an upcoming project!! A few side notes: The clean tone is much better than I expected. Even using the same eq settings as the gain channel, I got a nice, chime-y clean tone. Not harsh at all. I'd be totally fine switching between the clean and the distortion tones. The hiss, while certainly present, isn't as bad as I've read about. And, it doesn't really get any worse between 3-6 on the pre-amp gain. With how loud the amp will be played in a band situation, I'm pretty certain I'd never notice it. Running the 5150 through my Boogie Recto cabs is just pummeling!! Great note definition, and really nice an' tight low end. I had the master volume at 4, and . My neighbors probably weren't too thrilled. Stoked!!!!
