The Mini Superbeetle Bass is the perfect bass amp for that '60s rock sound. Powered by Nutube, it delivers the stunning sound quality that can be attained only by real vacuum tubes. The speaker cabinet uses a unique bass-reflex structure to obtain the low-end required by a bass amp. Also new in the bass model is a compressor that's an important part of shaping your sound, providing good sustain and consistently tight and stable tone. The four-band EQ, optimized for bass players, allows for a more detailed control of the tone. The new fuzz on this model is tuned to the sound of the '60s. This means that no additional equipment is needed to produce the fuzz bass sound of that era.
