This is the Diamond Bass Comp Jr compression pedal. It's the gold-standard optical compressor pedal. Here's a rundown of the controls:COMP: This adjusts the amount of compression. Turn it clockwise for more compression and a more narrow dynamic range. Turn it counter-clockwise for more subtle compression and a wider dynamic range.EQ: This adjusts the tone of the compression. Turn it clockwise for brighter compression. Turn it counter-clockwise for warmer compression.VOL: This is the output volume of the pedal. Once the other knobs are set where you like, you can adjust this to unity gain with your dry signal. Or you can crank the VOL for a big level boost, or to drive your tube amp to overdrive.900/250: This toggle selects the center frequency of the tilt EQ control. The up position is 900 Hz. The down position is 250 Hz.This pedal is in very good condition. The electronics work perfectly. The pots, jacks and stomp switch are all clean and quiet. It will come in the original box with the printed instruction sheet. You can power this with a 9-volt battery, a 1Spot or Boss PSA-style ac/dc adapter, or with your standard 9-volt pedalboard power supply.
