The Catalinbread Clean Little Secret foundation overdrive pedal refines the low-gain British amp-in-a-box concept for players who want an always-on enhancer, edge-of-breakup response or a focused push into an amplifier. Its analog op-amp circuit remains clean and open through much of the Pre-Amp range before adding increasingly textured overdrive past roughly 1–2 o’clock. Independent Bass and Treble controls provide detailed 2-band shaping while interacting to alter the perceived midrange, and the high-output Master control supplies enough level to strengthen a clean sound or drive the next gain stage harder.

Pre-Amp Control Moves From Sparkle to Low-to-Medium Gain

At lower settings, the Pre-Amp control adds light coloration and low-gain sparkle without overwhelming the character of the guitar and amplifier. Turning it beyond the middle of its range introduces more edge, harmonic texture and overdrive, topping out in low-to-medium-gain territory. This makes the Clean Little Secret useful as a foundation tone, clean boost or light drive rather than a dedicated high-gain distortion.

Interactive Two-Band EQ Shapes the Midrange Indirectly

Separate Bass and Treble controls provide more focused shaping than a conventional single tone control. Raising both creates a relative mid scoop, while lowering both produces a stronger apparent midrange. Because the controls interact, small adjustments can shift the pedal from broad and open to more concentrated and forward without adding a dedicated mid knob.

Master Output Supports Always-On and Stacking Roles

The Master control provides additional output above unity, allowing the pedal to function as a clean enhancer, light overdrive or boost into an amplifier or following drive pedal. One 1/4-inch input and one 1/4-inch output make it straightforward to integrate into a mono pedalboard signal path. The pedal accepts a standard center-negative 9–18V DC power supply, sold separately.
