Gallien-Krueger Amps - GK MB112 II

SOLD - Contact us for more options

The Gallien-Kruger MB112-II Combo Bass Amp is the quintessential grab-and-go combo, plus it's ridiculously lightweight at 28 lb, yet immensely big with its 200 watts of all-digital power. On its back panel it has a 4-band active EQ (Treble, Hi-Mid, Lo-Mid, Bass) to customize your sound, and a gain control to add in a little extra oomph. Perfect for smaller clubs and practicing, it has the nice addition of a Chain output so you can connect to other GK MBP-powered cabinets for even larger venues.


Rugged construction means it's built to last and it's quite portable, standing 17 1/2" high and 15 1/2" wide. The Gallien-Kruger MB112-II Combo Bass Amp is an efficient and practical combo that won't your back or your bank.
