i played with it a little friday night. i am going to play with it some more today before making final judgement on it.
so far, my thoughts based on friday's little play time:
good:
can load Ownhammer IR with no problem.
has many amp models and effects to choose from.
harmonizer tracks well enough to use.
bad:
sounds flat and 2D.
amp models don't act like the real world amp does.
master volume is only a volume control, so no power amp distortion.
the reverb has no real stereo width.
no pre-eq to tweak the front end of an amp, have to use a tube screamer.
i felt like it wasn't fair to compare it to the eleven rack, it's just not a fair competition. for basic tone, the eleven rack wins.
i will compare IR loading against the epsi today and delve into the gsp1101 a little more though.
