I'm looking to replace my current head, and I'd be interested to hear your suggestions! I currently have a GK 400RB head which has been a solid, reliable tank for 10 years now...but it's just not powerful enough. It was fine for a while, but I've just outgrown it. The gigs are getting louder and the venues are getting bigger. I'm assuming that I will need at least 350 watts or so. I need to stay under $1000. I'm leaning towards Ampegs, though I don't know which model would be best (SVT3 Pro, SVT-350H, etc.). Any thoughts? My cabs are an old SWR Goliath I 4x10 and SWR 1x15. Thanks!
