GK 400RB-III

Discussion in 'Amps and Cabs [BG]' started by rawlsjk, Feb 1, 2004.


  1. Hey everyone. I had the power amp circuit board blow out of my GK 400RB-III head. I was trying to figure out if I should just purchase another power amp board ($180) or just buy another 400RB-III. However, I've been looking all over and I can't find a place that sells the III model. GK came out with the IV and that's all that I see advertised. Even GK doesn't have the III on its website anymore. If anyone could help me find a website that has the current price of the amp, I would greatly appreciate it. Also, could there possibly be problems with the preamp portion of the amp?
