removed the resistor at 'R10' position.. put a bit of wire from a dead pedal in it's place.. sounds great - went from about 15 repeats to infinite repeats. on the edge of oscillation at around 3 o'clock.
lots of cool sounds to be had with the Hi-Cut knob too.
Compared to the same mod on the Danelectro PB&J, it's more like you'd expect an oscillating delay to react; with feedback cranked, **************** gets loud.the mod itself is far easier to do since it's not a tiny little SMD chip being removed, but a normal resistor.
on the PB&J the repeats don't get as super-loud, they just get grimey and distorted/crushed.
