Get Professional Performance in a Lightweight Package - The Gallien-Krueger MB 115-II 200 Watt 1x15-inch Bass Combo Amplifier

The Gallien-Krueger MB 115-II packs 200W into an ultra-light 38lb package.  The sound comes from a GK-built single 15" driver to give you great bass tone but in a combo amp that can go anywhere. Four band active EQ and contour based on the legendary 800RB provide extensive tone shaping capability. Effortless transport for rehearsals and 200 watts of power through the 1x15" speaker allow you to be heard in moderate size venues. Tough vinyl covering protected with metal corners provides lasting protection.

  • Ultra-Portable Performance
  • Custom Speaker Design
  • Enhanced Connectivity
  • Variable Q
  • Switch Mode Power
  • Internal Circuit Protection
  • Driver By GK
  • Ultra-Light Weight

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.

Variable Q

Inherited from the 800RB, this unique design varies the EQ bandwidth to retain a musical response even at extreme settings.

Switch Mode Power

Extremely lightweight switch-mode power supply and power amp deliver 200W into the speaker with very little wasted heat dissipation

Protection

Internal circuitry is always on the alert to problems, indicated at the power switch ring.

Driver By GK

Special driver with 2.5-inch edge wound aluminum voice coil, designed just for this cabinet, manufactured in the GK USA factory.

Ultra Lightweight

Internal bracing to ensure tone-robbing leakage of sound through the walls of the cabinet is minimized. Plywood construction, aluminum chassis, switch-mode power supply, and power amp deliver 200W performance in a rugged 38lb package.

Critically Damped

GK's design team tuned the ports for optimum performance while coupled to the cabinet's specific designed speaker. The ports coupled with a specific jute blend of damping material provide the right amount of damping at the right frequencies, for optimum response.
