They definitely are diverse amps. I had a JCM 800 for a few years.. The 1959 Model 100 watt head.. No master volume. No gain knob.. Was balls to the walls loud. It was ear piercing by the time you got it loud enough to overdrive it.. Sounded great though. Sold it because I was getting this. Sold my Triple Rectifier because I was getting this, too. Selling my Fender 140 tube head, because I have the 500x. It can do Mesa grit, Marshall dirt, Fender clean.. So, no need for me to have those amps sitting here collecting dust. I'll still have my handful of tube amps.. I have 3 of them left and 2 I definitely won't ever sell. Ultimately, if I start gigging on a large scale again.. I'm going the tube power amp route and using the 500x as the preamp. Get myself one of them ISP rack noise reduction units.. A spare power amp.. Probably a Rocktron Velocity.. Wireless.. 1-2 other things.. And I'll be set.
