I finally get the 210 (Delta) to match. Nice little unit. Doesn't handle the low A too well, but I only tune that low for a few songs. "C" is where we normally play, and the 10s handle that fine. This brings me to my new problem, the Crate head that I use. It's the BXH 220 model. The preamp clips way too easily when you try to push any low frequencies, especially with my Warwick. I have to keep the low frequencies flat on the amp and live in the low mids if I want any kind of volume. I actually get more useable sound when I bypass the preamp with my old guitar effects processor! In short, I've decided I need a new head. It's a long drive to any kind of decent music store from where I live, so I'm probably going to be forced to mail order. My upper limit is about $600, depending on my tax refund. I want something that will match up well with my Avatar cabinets and doesn't mind being "pushed" and maybe give me a bit of grind. I'm looking at the plethera of $300, 300 watt heads and beyond up to the Ampeg B2RE. I've searched most of the heads and what I'm hopig for is some input from my fellow Avatar users. Any advice will be mucho appreciated.
