Dr Scientist Dungeon Crawler Heavy Distortion Pedal

The Dungeon Crawler is MOSFET based distortion pedal that’s designed to take a clean amp all the way to a death metal tone. Or a doom metal tone, or a black metal tone.. an extreme metal tone!

Based around 3 high gain MOSFET stages and 6 gyrator EQ stages, the Crawler is voiced to emphasize pick attack, high gain, and aggressive tone. The Grind knob adds the output of a silicon rectifier to take the tone even further while the custom comparator based noise gate keeps your extreme tone under control.

Features

• High Gain MOSFET Design
• Active 6 Band EQ using gyrator (op-amp simulated inductor) stages
• Boost Stomp for a nice increase in both gain and volume
• Custom comparator based noise gate
• High quality analog signal path with film capacitors
• Premium parts and components throughout
• True Bypass with soft touch relay switching
• Full control over wet/dry mix
• Top mounted audio and power jacks
• Designed and handmade in B.C., Canada

Knobs

• Gain – Increases the amount of distortion
• Grind – Blends in a silicon rectifier for a grindier tone
• Volume – Controls the effect signal level
• Lows – Adjust the low frequencies, post gain
• Lower Mids – Adjust frequencies around 420Hz, post gain
• Upper Mids – Adjust frequencies around 1000Hz, post gain
• Highs – Shelving treble filter at 3kHz, post gain
• Mix – Adjusts the balance between the input signal (Dry) and the effect (Wet) signal
• Thick – 130Hz pre-gain filter
• Presence – Resonant 1000Hz filter, post gain
• Gate– Turn down for no gate, increase for stronger gate
• Boost – Engage for increase in Gain and Volume
• Bypass – Engage or disengage the effect
