The mellow sibling to Catalinbread's Dirty Little Secret. Where the DLS chases cranked Plexi roar, the Clean Little Secret goes after the low-gain Bluesbreaker sound — chime and edge-of-breakup dynamics rather than British high-gain snarl.

Four knobs: Pre-Amp, Master, Bass, Treble. The op-amp circuit stays glassy clean until you push Pre-Amp past noon, then it starts to grit up without ever losing control or heading into anything metal territory. Bass and Treble are separate and interactive, so you can shape mids by pushing or pulling both together — more range than the single tone knob most low-gain drives give you. Master handles output level, letting you push the front of your amp or just balance volume for an always-on setting.

Works well as a foundation tone, a transparent boost, or stacked in front of a dirtier drive. Compact enclosure, true bypass, top-mounted jacks.

Runs 9–18V DC, center negative, low current draw.
