Caveman Audio BC1 Bass Compressor

Caveman Audio BC1 Compressor
 
Just like their preamps, this Caveman Audio BC1 Bass Compressor pedal is magic!
It unbtrosively makes you sound like a better bass player.
It gives you full control of the attack (response time), release (sustain time), and threshold (sensitivity to input signal level).
Of course you can control the output level, but there is also a separate Boost level control so you can instantly switch in a bit of boost (or cut) without having to touch the main Level control.
The switches on the rear are for Instrument or Line level, Series or Parallel mode, and Ground Lift, as well as both Balanced (XLR) and Unbalanced (1/4") inputs and outputs make this a totally pro grade "always on" compressor suitable for your most important shows and recordings.
