Eldritch Blast

Eldritch Blast is a fuzz built around a high-gain octave/intermodulation generator. This unusual transistor circuit is capable of heavy, complex riffs or touch-sensitive textures with a ripping, splatty octave up. And its switchable active EQ invokes sinister high-gain tones worthy of the outer gods.

The development of the Eldritch Blast has origins in the early days of EAE. It is a greatly expanded take on theMagic Missile Fuzz, an old design of ours which is an homage to the modern classic fuzzes of Devi Ever, Tim Escobedo, and all of the circuit-bending weirdos on ilovefuzz.com. We teamed up with Alec fromMask Audio Electronics(MAE) to flesh out and fine-tune the design, and together came up with a result which significantly diverged from the original Magic Missile circuit.

For Eldritch Blast Version 3, available starting in April 2023, we revisited the function of the Chaos toggle. Rather than the gated mode of previous iterations, the Chaos toggle now engages a dynamic oscillation mode that creates sub octave glitches, atonal arpeggios, and other strange sounds that we havent discovered yet. If you have a V2,see here to get yours retrofitted.

Finally, wed like to thank Dan fromAudio Disruption Devicesfor the stellar art design!

Electrical Specifications

Bypass: Relay switching with true bypass

Input impedance @ 1 Khz: 220k

Output impedance @ 1 Khz: 1k

Power: 9V DC, 2.1 mm center negative barrel. The current draw is 80mA with both channels engaged.

We recommend a regulated, isolated power supply rated for 100 mA minimum. The PSU input is protected against reverse polarity. Our pedals do not accept batteries.

Controls

• Gain: Controls amount of gain and low frequencies at input. Turn clockwise to add gain and thickness.

• More: Controls amount of signal feeding octave circuit. Use to adjust the sensitivity of intermodulation textures.

• Tone: Active peaking filters working on the highs and midrange simultaneously. Only in use when star footswitch is on.

• Bass: Active peaking filter centered around 100 Hz. Only in use when star footswitch is on.

• Volume: Loudness amount.

• Splat: Shifts the dynamics and gating of the transistor stages, switching between a smoother character or a harsh note decay with splatty artifacts.

• Mode: Changes transistors in the octave generator to change the texture and amount of saturation.

• Chaos: Engages a self-oscillating mode with highly interactive squeals, squealches, and sub-bass drones.

• Engage Footswitch: Master bypass.

• Star Footswitch: EQ on/off.

Changelog
