Troy van Leeuwen “TVL” Raven Filter and Boost

ENVELOPE FILTER

BOOSTER

The TVL Raven is the second pedal in the signature series created by Dr. No in collaboration with Troy van Leeuwen. It features two distinct sections: a filter and a booster, which can be used independently or together. The filter section uses a “Raven Skull” knob that switches among three capacitor-based frequency ranges, plus a “Q” potentiometer to control resonance or bandwidth. The booster section is a volume-boost control that lets you dial in clean gain. The design is handmade, includes custom cosmetic touches tied to the TVL series, and complements the TVL Octavia in the shared tonal vision. The Raven and Octavia were both used on QOTSA’s Villains album and tour.
