The Hartke Kickback Series 1215 120 Watt 1x15" Bass Combo Amp is also know as the "big bottom" Kickback combo because of its incredible and surprising production of powerful low end frequencies. Its versatile "two-way" design has all the bass you'll ever need thanks to its massive Hartke 15" aluminum-cone driver, 120 watts, fully adjustable Shape control, 3-band EQ and more. Flexible enough to be played upright or "kicked back" as a monitor, Hartke's Kickback quickly became one of the most imitated (but never duplicated) designs in bass. Now it's available in three different versions for all kinds of applications from home practice and rehearsal to club dates and small theater venues.
