Hey Mitch, I just got my GP-1000 in the mail from ebay!
I tried messing around with it and I tried putting the settings on the ones you list alexi has.
It's really weird though, it's like you say he has the channel 2 volume at 11 o clock. Whenever I put mine higher than 9 o clock (at all) it's like fucked up. Like anything quieter like hitting a note softly or hitting a palm mute is loud, and then whenever anything like a normal note or a chord is hit its really quiet.... also there's a bunch of noise. I tried messing around with teh settings on my amp, and the weirdest fuckin shit happened... it's like when i move my treble past 12 o clock on my amp it makes this weird fuckin noise....
Also whenever I hit a really high note like the 24th fret on the high E string, it like "buzzes" (dunno how else to describe it).......
What the heck am I doing wrong?
