The Mesa Boogie Cabclone is a quality load box and highly convincing speaker simulator -- just plug your head straight in and take the sound of the amp straight to your audio interface, the front-of-house mixer, or even your favorite set of headphones to hear the pure sound of the head. The front panel sports a DI level control, polarity reversal, ground lift, and three switchable voices which emulate closed back, open back, and "vintage" cabs. The rear panel has all the I/O you'll need, with an input rated up to 150 watts, a thru to go into a live cabinet, balanced direct out, +4dB line out, and a headphone output.
