Sometimes called the best amp you've never heard, the 1950s Bell and Howell Filmsound 385 projector, with the right modifications, could deliver vintage tube overdrive with an elegantly simple two-knob interface. Add an updated version of that iconic mod to your pedalboard with the 385 Overdrive MKII.Known for its responsive, amp-like dynamics, the original 385 became a favorite for guitarists chasing touch-sensitive overdrive with rich harmonic content. The MKII expands on that formula with an A/B switch that gives you two sets of Volume and Gain controls for toggling between rhythm and lead tones or stacking distinct levels of drive on the fly. The 385+ mode punches the circuit harder for more saturation, unlocking a thicker, high-gain response when you need extra push. With independent Bass and Treble knobs in place of the original amp’s shared tone control, the MKII allows for more precise sculpting to dial in scooped mids or a more aggressive bite. Internally powered at 18 volts, it delivers extended headroom and greater dynamic range, making the pedal feel reactive to your playing, just like the tubes in the original. Designed for players who appreciate tube-style grit and organic response, the 385 MKII balances vintage roots with practical updates that keep your tone flexible and gig-ready.Walrus Audio 385 Overdrive mkII FeaturesInspired by the vintage Bell and Howell Filmosound 385 projector amp, long praised for its warm, tube-driven character.Reimagined in pedal form, the 385 MKII delivers touch-sensitive, amp-like overdrive with rich harmonic detail.A/B switch offers two sets of Volume and Gain controls, ideal for switching between rhythm and lead tones without changing your tone stack.385+ mode slams the front end for thicker saturation and higher gain when the song calls for more bite.Independent Bass and Treble knobs give you flexible EQ control beyond the original amp’s single tone circuit.Runs internally at 18 volts, giving the pedal increased headroom and a highly dynamic response that reacts to picking strength.Built for players chasing tube-style grit with modern flexibility, the 385 MKII adds useful features without losing the soul of its inspiration.Walrus Audio 385 Overdrive mkII SpecificationsTrue BypassThe 385 MKII is available in two different versions: 1.
