Great overall amplifier

From crystal cleans to crunch to a dirty brown sound. The Two Rock Bi-Onyx does it all. Its very very pricey. But, it is well worth the price as it does it all and does it all well. Its right up there with the Vox AC-30 and the Marshall JCM800 in build quality and in tone and in sound.
