I'm looking into these two amps for my new rig. Rmcaudio sells the 2001rb for $1080 and most places Ive seen sell the GB for $1200, although i found a site that had them for $1100. I use to own a old series 1001rb before they bumped it 200 watts, and it sounded great but didn't have the power to cut threw my guitarist dual rectifiers. I also use to own a GB tube works mostvalve 1x15 combo which had the best tone of any combo Ive ever owned but only had 150 watts so its worked with my funk/hip hop band but got lost when i played in my metal band. Basically i would like to hear what the gear heads have to say about these two heads, and also Id like to hear what other heads in this power range you guys recommend.
