The extremely limited edition Stomp Under Foot Sustainar--based on the the vintage ELK Super Fuzz Sustainar, a Japanese Big Muff copy. Only 10 of these were produced by Stomp Under Foot back in late 2017.
We just found a couple of these hiding in our warehouse. This is a brand new pedal from a factory-authorized Stomp Under Foot dealer. Includes original factory box.
