I know this says Rat lovers unite......but I won't be uniting.....specially since I don't know you well enough......
But just to be oppositional, I bought a ProCo RAT in the 80's when they came out. I still remember the ad for it in GP and it listed all these players using one, and I liked them all just about. So I bought it. (i've grown out of that method of choosing gear BTW
Well, I hated it. I could not get a sound out of that thing to save my ass. I tried all kinds of guitars and amps and all it did was sound fuzzy, whooshy, buzzy, thin, oversaturated, bassy while bright etc etc etc and was like the worst fuzz pedal from the 60's on steroids. Hell, even my old 60's "one-sound" Fender Blender sounded better.
So I 86'd it pronto. I cannot remember if I sold it or took it back.......I think I took it back. I generally do not buy gear I let go, so you know I did not like it.
That said.............I cannot get a tone out of a Mesa Boogie Mk *whatever* to save my life either......but I love the sound of them when other guys play them. I have a ProCo RAT emulation in Digidesign Eleven Rack and it is still not my favorite distortion, but I do use it occasionally.
I reckon if I found a RAT at a yard sale for cheap enough...I'd get it and revisit the situation.........but no way would I pay full pop for one. knowing I'd likely hate it all over again.
Just my take. I still like the way other guys sound using them.
