I just bought one of these little gems and can't put it down! The AC30 emulation is uncanny, what with available overdrive (which I don't use, as I play clean) and tone. I plug it into the output of my ZOOM 508 effects box and into a pair of noise cancelling SONY headphones. It's heaven:...no feedback (from my better half, that is). The unit is somewhat flimsy, however and I am thinking of modding it into a nice little metal box, with input/output jacks as well as a DC jack and normal size pots.:idea:! The main problem I see is replacing the thumwheel pots (VOL/GAIN/TONE) with the panel mounted ones; removing the PC board mounted ones looks like it's going to be a bear. They have 5 lugs, though I suspect the outer ones are just for mounting on the board. But it's tight in there! An additional output jack will be installed in parallel with the existing one but with with an attenuator resistor, for use as a line out into my Laptop (with Audacity)...my laptop does not have a line input, only a MIC level one. Any thoughts on this? Has anyone done it yet?
