So I've been in the market for a new amp for quite some time now, and my dad just handed down to me his early 80's Yamaha G100-112. I just plugged it in for the first time to play it, and overall it's a decent sounding amp. The drive channel is kinda crappy, but really I'll be running any amp on the clean channel and running my rig into it. Earlier today I also found an '82 Fender Concert 112 amp made by Paul Rivera, so all hand-wired and such. I haven't been able to play this amp yet nor have I ever played on the Fender Concert amps before, but I have heard good things. I play many genres but mostly jazz, blues, and rock. With that being said I'm not sure whether to sell the Yamaha for the Fender. Has anybody played both of these and can give me some comparison on the two? Any other input is welcome.
