Thia amp is badass. I had the good fortune to find the Top AND bottom stack at a second-hand store Silent Auction for $300. I replaced ALL the Scorpion Speakers with brand new Scorpions and it sounds amazing. Although the amp weighs almost 100 lbs, it is quite the work horse....
for second, i thought, wow they've really nailed that riff, lol, I think these amps are meant to be really transparent, so whatever effects you use, will shape the tone, imo you cant go wrong with old peavey amps.
