FS: Super Hard Treble Boost

Knocked this up the other day from a few bits of old projects lying about, based on a certain well known boost which can be very hard on your amplifier. It crackles but it's fine...

Simple stuff, it's a one knob treble booster, battery powered in yer standard MXR sized case. Anything from some added shimmer to a real kick up the arse for a valve amp.

Willing to let this go for cheap as I drilled the LED hole off center and it looks slightly wonky. Currently sitting in an unpainted box, which I can spray red, yellow or green to your choice.
