Gallien-Krueger GK 2000CPL 1980s Guitar Preamp effects processor RARE *READ There’s a slight hum when you power it up - we were able to test it using an iPhone as an input and headphones as the output - NO HUM on the headphones. - initially there was static on the pots- but that that has been cleaned up with Deoxit. No static. The Reverb Pot is missing a knob, we’ve reached out to GK to see if any replacements exist. Excellent condition otherwise. Seems to work great given its age - Rare 80/90s effects processor.
