I play in two hard rock/metal bands. I just bought a GK 700RB-ll new, but got it for $100 less at Guitar Center cause it had been there for a while & had some scratches on it. I absolutely love it. I got it with a GK NEO 410 cab. Great over all tone. I has a great low end without sacrificing the highs & mids.
My first gig with it I only had the volume at about 10am and the sound man ****. I had to turn it down to 9am. lol.
It has a setting for 4 or 5 string that you might find interesting.
Whether you go with this deal or not, I'd highly recommend the 700RB-ll.
