Glass Palace

The Glass Palace is a stripped-back, aggressive boost from Holy Island Audio, built to slam the front of an amp or push a fuzz harder.

A texture toggle selects between a clearer, crisper gain stage and a more unruly, broken one, so it works as a clean-ish level lift or a raw, gain-adding drive in its own right. It's a simple, high-output tool aimed at doom, sludge and heavy players who want more gain and volume on tap. Printed and assembled in Cardiff, Wales.
