Hi... I am looking at upgrading my rig. I have a lot of interest in the Kustom Groove Bass 1200 amp head. Do you think it would be an upgrade from my Carvin R1000 (first series)? Are there other heads I should consider in the $500 - $700 price range? My Carvin clips really early and is tearing my speakers up with the clipping. Plus it is barely powerful enough in my current band (Metal). But I have read that the Carvin's, even though they say 1000 Watts a 4 Ohms (what I am running), that they clip early and are more like a 300 Watt amp. Input? BTW- Cabs are: Avatar 212B and Crate 1x15 Pro Series with a new Peavey Black Widow 15".
