Hey guys, I'm new to the more powerful amps and cabs, I've pretty much been relying on my old Peavey TNT 130 for a while, which wasnt quite giving me enough power, so I finally came up with the money for a new rig. I went with Carvin stuff and got the 4x10 cab and R600 series 3 head. I played it for a while and really liked it, but when I turn up the master volume and gain past 12 o clock, anything below a low A gets a little distorted on me, not really alot, just a little dirty. I'm wondering if it's a wattage problem or is it just that I got what I paid for. I play a Spector Q4 and its a little better if I turn down the bass knob on it, but if I go down all the way I don't get the low end that I like. Any suggestions or comments are welcome. Feel free to bash Carvin gear because I've heard plenty of it from my buddies.
