On the block today, we have a Boss CE-1 Chorus/Vibrato pedal from the late 70's. All original and un-modded with some minor scuffs in the paint. The plastic knobs could use replacing (eBay sells an exact replacement knob kit for these for $17) as they are a bit brittle and cracked. The rubber feet on bottom are also missing as this unit has been board mounted. No scratchy pots or other noise issues. There is a bit of a volume drop on all of these units, but this can be easily fixed by changing an easy to get to resistor. There is a reason this pedal is considered the holy grail of all chorus pedals. The sound is simply inspiring, and worth every penny of the $450-$550 these things have been fetching as of late. SOLD!
