MarkBass Ground Stereo Pre

The Alain Caron signature model stereo preamp takes the form of a foot pedal and offers an array of inputs and outputs, including a stereo effects loop, stereo balanced DI outputs, Aux in, and Headphone output.

You can take the preamp onstage or off—you can use the unit’s headphone output for private practicing; or you can connect an iPod or MP3 player to the Aux input for learning recorded music or playing with backing tracks.

Although it can be used mono, the Ground Stereo Pre is designed to be used in stereo with two BAS 121 Lite two-way powered cabinets and stereo effects. Each channel includes 4-band EQ.

The preamp features separate Gain, 4-band EQ, and Mute switches for each channel; Master Level control; Effects Loop Bypass; stereo pairs of input jacks, outputs jacks, and XLR line outs; Stereo Send / Return for external effects; a Mono / Stereo switch; ground lifts; Pre / Post EQ and Pre / Post master switches for the line outs; and Tuner out, Aux in, and Headphone output.
