My first amp was a Crate GX130C 2x12 combo, which I used in conjunction with an ART SGX 2000 Express digital preamp as a front end boost. Both are early-mid 90s tech and sound it. The GX130C had a great clean and stereo chorus option but sounded like boxy, clacky garbage distorted.
The amp would randomly switch channels from clean to dirty. We found out later this is because there was no cooling fan and once the solid state components reached a certain temp well--who knew what would happen!
Crate, based out of St. Louis, along with Peavey were usually competing in the 90s South in the low to mid tier gear market. They were the Spiders of their day.
My best friend from high school did electronics in the Air Force. He cut a circular hole in the cab for an exhaust/cooling fan (I forget which), and then the problem with the Crate stopped.
I later gave the amp to one of my students' father.
The cab itself was sturdily built and was certainly like a crate in that sense.
I used it for a coffee table for longer than I played music with it. Had cup ring stains and everything.
Moral of the story: if you don't like the amp, maybe you can use it as furniture.
As for Line 6, this takes me back to their high end amp of the period, the Vetta.
A Vetta 6 is listed in Sweetwater at $1699. I'm guessing this is when they were new.
A perusal of used units shows them going for $350-1200 dollars.
