From Midfi creator Doug Tuttle:
"Over the years I’ve plugged my guitar into the mic input of pretty much every piece of consumer electronics I’ve come across. A few were total magic and this pedal is a tribute to those. "
The Yard Sale captures the spirit of those consumer audio electronics, "A little hissy, a little blown out/saggy, fairly low input impedance, and extremely fun to play."
(Cleans up with your instrument’s volume control really well too)
