I have a lightly used H.B.E Hematoma up for grabs, I love the pedal but need the cash. Will sell for $110 shipped to U.S.A, Paypal is ideal. Thanks There was a dude that did a review that said the blue knob Hematoma sounds better than the purple knob. H.B.E reported that the only changes made where cosmetic. So some folks think blue sounds different than purple! LOL. This is a great sounding pedal.
