INV 9565 The Electro-Harmonix Big Muff Crying Tone Pedal is a rare 1970s wah/volume pedal from EHX’s early lineup. Unlike the fuzz-based Muff pedals, this unit is purely a wah effect (sometimes called the Big Muff Pi Crying Tone Wah) and is prized today as a collectible vintage piece. 🎸 What It Is Type: Wah/volume pedal (not fuzz/distortion). Era: Released in the 1970s, part of Electro-Harmonix’s experimental pedal range. Design: Similar in spirit to the Crying Tone series, but branded under the Big Muff Pi name. Functionality: Provides expressive wah sweeps and volume control, rather than the saturated fuzz tones associated with the Big Muff Pi. 🔑 Key Features Pure Wah Circuit: Unlike the Muff Fuzz Crying Tone, this pedal does not add distortion — it’s strictly a filter effect. Vintage Build: Heavy-duty casing, typical of EHX’s 1970s pedals. Collector’s Appeal: Rarely seen compared to the standard Big Muff fuzz pedals.
