    Product Description

    Gargantuan Gallien-Krueger power and tone in portable packages — that's the MB Series for you! Ranging from 25 watts to 500 watts, these modern bass combo amps deliver peerless performance for contemporary bassists; featuring intuitive sound-sculpting controls, robust constructions, reliable digital power supplies and power amps, and lightweight speakers designed and manufactured by GK in the USA.

    MB108 Combo

    The MB108 is the smallest bass amp combo in Gallien-Krueger's MB Series, but it still delivers glorious GK tone despite its compact proportions! With a 25-watt power amp and ceramic 8" speaker, the MB108 is perfect for home practice sessions and has enough volume even for intimate gigs.

    Key Features

    • 3-Band Active EQ — Lets you tailor your tone, by boosting or cutting the bass, middle and treble knobs.
    • USA-Designed Speaker — The special ceramic driver with 1" copper voice coil, designed just for this cabinet, is manufactured in the GK USA factory.
    • Lightweight Design — Aluminium chassis, switch mode power supply and power amp deliver 25W performance in a rugged 17.5lb (7.9kg) package.
    • Contemporary Connectivity — Aux in and headphone output for silent practice. Don't let the neighbours prevent you from playing!
    • 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.
    • Protection Circuitry — Internal circuitry is always on the alert to problems, indicated at the power switch ring.

    About Gallien-Krueger

    Gallien-Krueger might not be the first name that comes to mind when you think "bass", but you might be surprised by just how many of your favourite bands have a GK locking down the low-end! Flea uses them, Duff McKagen is on their artist roster, and even jazz legend Dave Holland uses GK to amplify his double bass. A quick look at the sheer variety of artists will give you a clue as to how versatile these amps are!
