I picked up an old Yamaha G-100 amp head today for a little over $100 - I can't try it out yet, because it wants a 4 or 8 ohm cab, and I don't have one on hand. I'm hoping to get a lot of clean volume so my son can use it with a Tonelab for some gigging he's doing. It looks rugged and well made - even though it's, um, solid state. It would be cool to have an amp that capable of some loud clean spank action in any event, so that's what I'm hoping for.

Anyone use one of these?

Which ToneLab does he have?
VP
 
Those Yamaha are some of the best sounding solid state amps that I've owned. I had a G50-210 combo in 1980 and I often wish that I had kept it.
 
Tonelab SE -- generally we're really happy with it after putting in a 12AU7 tube and re-calibrating it (there was some crappy clipping going on before that, like maybe the 12AX7 was pushing the subsequent circuitry too hard) - it would be nice if the foot pedals had more traveling distance, but what're you gonna do?

That's encouraging to hear about the old amp you had Ocnor.

We tried out the G-100 head last night by disconnecting the speaker leads from a combo amp and using a speaker cable with two leads on one end to plug the G-100 up -- keeping all the knobs on zero to start, so we wouldn't blow the speaker. Rats - the thing's a boat anchor right now - just some rhythmic whooshiness, possibly from the tremolo circuit, and no discernible sound that bore a resemblance to what we played on the guitar :( - oh well, you get what you pay for. I'm going to take it to a tech.
 
OK - got it back from the tech the day before yesterday - he said there was a bad capacitor - I didn't ask more - probably a big electrolytic one.

Anyway, here's a pic:

We picked up a 4x12 Randall cab (and head) a while back, and so I plugged it through. We got what we were looking for: oodles of clean sound pressure. I might think about getting higher wattage rated speakers at some point, because the ones in the Randall cab got pushed a bit. We played with the distortion and effects, but couldn't really get into them, at least for now, but it's the clean spanky sound that's driving this anyway. The reverb wasn't too bad.

Why couldn't you just rewire a cab you already had?
