Check the listing for details. Morley 20/20 Lead Wah Boost Pedal. Condition: New. Listed at 199.00 USD. Pedalboard-friendly Wah That's Tailor-made for Soloing The Morley 20/20 Lead Wah Boost combines the tonal character of two high-gain-voiced wah-wahs into one pedalboard-friendly unit. This pedal absolutely rips, thanks to its wide sweep and mid-focused sound. Set the boost at 12 o'clock for a killer boosted-wah tone, crank it to elevate every note of your solo above the fray, or pull it back for subtle wah-soaked textures. There’s a reason why Morley’s electro-optical design receives so much acclaim around Sweetwater — its whisper-quiet operation makes noisy pots seem downright antiquated. The 20/20 Lead Wah Boost’s switch-less operation makes it a breeze to activate — just step on the glow-in-the-dark treadle to engage the wah and boost simultaneously, and step off to bypass.
