• Channel one produces a warm and sparkly clean sound, reminiscent of a piano,. It has immense overhead, whenever a very loud, but crystal clear clean tone is desired.

• Channel two is a dual purpose channel, it's two voicings can be selected with a toggle switch. The (-) mode of this channel has dynamics to range from a vintage type clean sound to a broad crunch. The (+) mode of this channel offers similar voice, but much more gain. Both modes provide ample pick sensitivity.

• Channel three offers a high gain structure, but again with very good pick sensitivity and easy control. The distortion structure is transparent, but yet percussive and brutal.

Herbert Amplifiers have a selectable mid cut feature, assignable to all channels. This adds tremendously to the versatility of the amp. The mid cut feature has a compensation control called "level". This allows the guitar volume to be compensated in the event of the mid cut being engaged in mid song.Herbert's master section features dual volume controls, and global presence and deep control knobs. Master effects loops are switch-able serial loop, parallel loop, and serial loop.
