From the vendor
Based on the ProCo Juggernaut
A Rat for bass with an effects loop and blend! Provides three functions: a versatile distortion unit, a mixer to combine distortion with direct sound, and an effects loop for use with external processing devices.
Controls for distortion amount, filter cutoff and volume level let you preset just the right degree of overdrive, tune in on the presence without any tinny treble, and balance the output for that perfect extra boost.
There is a master volume pot provided to control overall output level.
Dimensions: 110.5 mm* 39.4 mm Enclosure Fit: 1590BB Landscape Jack Fit: Top or Side
