Inspired by the vintage Bell and Howell 385 Filmosound projector, Walrus has created a dynamic and responsive overdrive modelled after the projector’s tone. Guitarists have modified and used these as guitar amplifiers.

The 385 was developed to have the same simple but effective tone control as it’s older relative, but unlike the projector, the 385 breaks up the single tone control and integrates separate, boost, cut, bass and treble, allowing the player to have full creativity to create tones at ease.

The pedal features original artwork of a vintage Belle and Howell 385 projector by David Hüttner to make your pedal stand out!

Key Features

  • A/B switch – This gives the pedal two separate sets of volume and gain. Use it like a preset to change the volume and/or gain for specific parts!
  • 385+ Switch – This adds an additional gain stage at the front of the pedal for thick, saturated overdrive with more sustain.
  • Internal Running at 18v – The pedal is internally running at 18v, which helps nail the same dynamic feel of the amp in a stomp box. This means it is extremely sensitive to how hard you dig in – just like the amp.

Controls

  • Bypass: Soft touch, relay true-bypass
  • A/B: Soft touch switch. Press to swap between using either A (White) or B (Red) Volume and Gain controls. LED indicates which controls are being used – White for A, Red for B.
  • Volume A: Controls the overall volume in the A setting.
  • Gain A: Controls the overall gain in the A setting.
  • Volume B: Controls the overall volume in the B setting.
  • Gain B: Controls the overall gain in the B setting.
  • Treble: Used to adjust the level of the treble frequencies.
  • Bass: Used to adjust the level of the bass frequencies.
  • 385+ Switch: When the switch is down, you are able to achieve classic 385 sounds. Flip the switch up to add an additional gain stage to the input of the pedal, achieving heavier gain sounds and driving the pedal harder.

Overdrive

Like a golden layer of melted cheese — warm, gooey, and just put it all over. It adds just the right amount of richness and grit, turning a clean signal into something smooth and savoury. Designed to mimic the natural breakup of a tube amp pushed to its sweet spot, overdrive delivers the flavour of classic rock and blues in every bite. From creamy mid-gain warmth to crisp edge-of-breakup sparkle, it’s the comfort food of guitar tone — simple, satisfying, and endlessly versatile. Whether it’s a mild crunch or a full-bodied roar, overdrive is where good taste begins.

Volume

Volume pedals control the output level of a guitar signal using a foot-operated treadle. They allow smooth volume swells, dynamic control during playing, and easy muting between songs. Volume pedals can be placed at different points in the signal chain to either control overall loudness or adjust gain and drive behaviour when positioned before distortion or overdrive pedals.
