I just got a GK 1001(not the II) to replace my fender bandmaster that I was using as a bass head. I loved the bandmaster, but the GK was too cheap so I had to get it. I have not had much time to play with it and I am happy with the purchase, but its just sooo clean. I really like the grit my bandmaster had and everyone talks about the "GK growl" and I have yet to be able to make it happen yet. Like I said I haven't played it very long, I probably haven't even spun every knob yet, but am I missing something completely? I use a fender P bass and Carvin 2X15 cab.
