Hello boys and gals
Bought this amp with the intent to use with my double bass rig (it is really light weight). But last week I manage to buy an Genz Benz 3.0 Shuttle +10T Combo, that is more suitable for the job.
Trades for Precision Bass (money your way if needed), but hit me with what you got.
The amp is serviced and RGC apart from some scratches on the corners of the tolex (I used black permanent marker to make it look better).

Specs from GK:

MB112-II Combo

The MB112-II is one of the smaller amps in Gallien-Krueger's MB Series II range, but it still packs a serious punch! With a 200-watt power amp and ceramic 12" speaker, the MB112-II is a killer companion for the gigging musician used to performing in small/medium-sized venues. It's great for practice too, with its auxiliary input and headphone output letting you jam along to your favourite tracks in silence.

Key Features

4-Band Active EQ — Derives from GK's legendary 800RB amp. Provides extensive tone-shaping potential so that you can find the sonic sweet-spot, especially with the 'Hi Mid' and 'Lo Mid' knobs.

Contour Control — Completely re-voices the amplifier by tuning between two different shaping circuits, with greatly different responses. When the the control is engaged, the low-end is slightly boosted, the mids are scooped, and the high-end is pushed up; great for slap!

Variable Q — Another feature inherited from the 800RB. This unique design varies the EQ bandwidth to retain a musical response even at extreme settings. In other words, it's hard to make the MB112-II sound bad!

USA-Designed Speaker — The special ceramic driver with 2.5" edge wound aluminium voice coil, designed just for this cabinet, is manufactured in the GK USA factory.

Lightweight Design — Plywood construction, aluminium chassis, switch mode power supply and power amp deliver 200W performance in a rugged 30lb (13.6kg) package.

Contemporary Connectivity — Balanced DI with pre/post switch, aux in and headphone output for silent practice, plus "chain out" to drive GK's MBP powered enclosures (pair with the 112 MBP).

Switch Mode Power — Extremely lightweight switch mode power supply and power amp deliver 200W into the speaker with very little wasted heat dissipation.

Critically Damped — The amp's port is specifically tuned for optimum performance, coupled with a particular jute blend of damping material that provides the right amount of damping at certain frequencies.

Smart Protection Circuitry — Constantly monitors for unsafe operating conditions such as short circuits, mis-wired speaker cables, blown speakers, improper ventilation, and incorrect speaker configurations.
