The Haxan by Stompbing Stones Pedals, is a vintage-voiced distortion/fuzz with some unusual controls (and parts: its circuit uses NOS military can opamps!): on top of your regular volume and gain knobs, it features two clipping modes, an extra boost, and bright/dark voicing options selectable via toggle switches.
The two clipping options are standard silicon diode (toggle switch to the left) or the brighter and more saturated jumbo double led (toggle switch to the right) which reflects the builder’s unconventional approach.
The boost circuit has its own separate footswitch.
