Piggy

Overdrive

SS/BS Mini workalike with external Sag control replacing internal Bias trimpot. JFET overdrive, broader range.

The Piggy is a Smallsound/Bigsound Mini workalike, not a direct clone. Several modifications: no internal trimmers (fixed-value resistors), a Sag control replaces the Bias knob (works backwards with a larger range), broader Bass sweep, and JFETs biased differently for a slightly fuller sound.

Volume, Gain, Bass (pre-OD passive HPF), Treble (post-OD passive LPF), and Sag (from gated/starved to full/clean). 9V DC center-negative.
