Morley Classic Wah Settings Guide
The Morley Classic Wah uses a light-dependent resistor (LDR) circuit rather than a traditional inductor — producing a different, smoother wah character without the inductor's mid-peak emphasis. No mechanical pot means no scratchy pot wear over time. The electro-optical circuit produces a sweep that feels different from Cry Baby-style wah pedals: smoother and less aggressive.
The best Morley Classic Wah settings start with: Sweep at 5/10. Adjust from there based on your amp, guitar, and room volume. For Rock Lead: Sweep 5/10.

Settings by Genre
Standard rock lead wah — the Morley LDR circuit produces a smooth sweep that suits extended single-note wah use on rock leads. No inductor peak means the treble content is more controlled and less harsh at the top of the sweep, which some players prefer for sustained lead wah use.
Moderate sweep range for rhythm — using the Morley for continuous rhythm wah benefits from the smooth LDR circuit that doesn't produce abrupt peaks during fast sweeping motions. The smooth electro-optical response makes continuous rhythm wah less fatiguing.
Heel-down parked position — the Morley with the sweep locked at a fixed position produces a mid-frequency fixed filter. The LDR circuit at fixed position produces a smoother, less resonant fixed filter than an inductor-based wah, which can sound more natural in some applications.
Toe-forward emphasis with the smooth LDR sweep suits aggressive lead wah over high-gain distortion, avoiding the harsher resonant peak an inductor-based wah can produce at similar settings.
A centered sweep gives a vocal, expressive wah character for blues lead playing, with the electro-optical circuit natural smoothness suiting slower, more deliberate wah phrasing.
Tips & Common Mistakes
- The LDR circuit activates automatically when weight is placed on the pedal, with no footswitch needed, and deactivates when weight is removed — there is no on and off click, just a smooth engagement. This is the primary practical advantage of Morley-style optical wahs over Cry Baby-style pedals for live performance: no missed engagements from a missed click.
- Because there is no true bypass in the traditional sense, the pedal always affects the signal somewhat when in the chain — players prioritizing a completely unaffected bypassed tone should compare this design directly against a true-bypass mechanical wah before deciding.
- The electro-optical LDR (light-dependent resistor) circuit ages differently from a mechanical potentiometer — if the sweep becomes inconsistent over years of use, the LDR component itself, not just the mechanical linkage, may need service.
- No moving mechanical pot means no pot-related crackle or wear over time, a genuine long-term reliability advantage over inductor-and-pot wah designs for heavily gigged pedals.
- The smoother, less resonant sweep character compared to a Fasel-inductor wah is a real tonal difference, not just a durability trade-off — worth an A/B comparison against a classic Cry Baby to determine which character suits a given playing style.
