Up for sale is a vintage MXR Dyna Comp Script BUD Box Compressor pedal in well-used condition.  This is the super early one with the aluminum BUD box and carbon comp resistors.  All the components on this pedal works exactly as it should without any issues - no scratchy pots and very responsive footswitch.  The battery clip has been spliced, but works exactly as it should.  Thanks for looking and ask any question you may have.  Cheers!
