Well, it sounds "nice"...
I have nothing to compare it to yet. I have only played it with the G12H-30 so far.
Last night Iplayed it for a few hours at our band rehersal. I have to say, when I could turn the volume up a bit it really sounds better than when just cracked open. I was playing my Tele mostly with the bridge pickup (one I wound myself to about 7 1/2K ohm) and in the middle with my neck P90. Very good, useable tones for all the classic rock and stuff we play, along with some stuff like Neil Young, The T HIp, etc.
I find it doesnt like to take all my pedals quite like the 15 watter - probably becuase of the fact the 15 stays very clean for much louder. But I was using my TS808 for my OD, and a BYOC 5 knob compressor and a Boss chorus and it was very good with those.
The amp has a ton of compression itself or so it seems.
ANyhow, it is a completely different animal than the 18 and 15 and that makes me happy, because I was looking for something different.
As you know it takes a long time to get used to the capabilities of a new amp and I am excited to try out some different speakers, different guitars, etc with it.
Got to go back to work now!
