A small word on the Blue Rumble. The Blue Rumble is our flagship, a 100W four+ channel amp with MIDI functionality. It can run either on EL34's or 6L6 valves with the flick of a switch (no biasing required). Each of the four channels has a dedicated gain and master volume control (clean/crunch/rhythm and lead). Both Clean/Crunch and Rhythm/Lead channels share a 3 band EQ (bass/mid/treble). The Lead and Rhythm channels have a Hi Gain function that gives it an additional gain stage and push in the low ends, which gives you an enormous amount of gain without sounding muddy.
On the master section you have the option of selecting one of two controllable presence settings. An additional Deep function lets you control the sub-frequencies. Last but not least, make your sounds/levels at the rehearsal room and control the overall volume with the master control.

It is designed to run on Celestion V30's but of course nothing prevents you from using other speakers.
This is one of the (if not thé) most versatile amp one can buy. Not by means of switches and controls, but solely judged by sound. Try one out at your local dealer if you get the chance.
