I am a huge fan of the Ashdown ABM amps, but never used the compressor or the sub-harmonics built in. From reading the description, this amp sounds like it's just an ABM without those two features on the amp front panel, but built into the circuit to be controlled via footswitch at fixed values. Not really sure this is needed in their product line, but it sure looks cool!
