Fully functioning & in great shape.
The Minivan is a dark echo, built off a digital chip so old it sounds analog. The mix knob is a pretty standard affair, from 100% dry at 7 o’clock, and for echoes just a touch louder than the dry, twist it all the way up to 5 o’clock.
Plug in an expression pedal to control the feedback amount, but it is a lot more fun to use a stereo 1/4” to dual mono 1/4” cable to insert effects into the delay line of the Minivan. For example, putting a pitch shifter in the loop will shift each repeated signal up as it passes through.
