Hands down our favorite outboard tremolo ever! So organic, so alive, and to soooo tube. Every standard tremolo you ever wanted but so much more.

The Delta-Trem™ recreates the richness, warmth and “feel” of vintage tube amp tremolo in mono or true S-T-E-R-E-O!
This is accomplished using vacuum tubes and an archaic, long-forgotten electronic device known as a “Raysistor“. A Raysistor is essentially a tiny filament lamp and photocell housed in a small metal can. This magical combination of vintage components enables the Delta-Trem™ to accurately replicate “bias” and neon/photocell tremolo effects, and a whole range of inspirational, unique tremolo effects.
The Delta-Trem's™ incredibly versatile LFO (Low Frequency Oscillator) generates anything from a subtle shimmer to deep, throbby amplitude modulation (AM).
In mono, use the Delta-Trem™ to faithfully reproduce the smooth, buttery pulse of an early Fender® “Tweed” Tremolux amp. Or delve deeper, for the more intense throb of a Fender “Blackface” Deluxe Reverb amplifier for some good ole Louisiana swamp blues.
In stereo, with two amps, the sound ping-pongs or swirls between them creating a huge, 3-Dimensional, spacious tone. This tremolo pedal always sounds exceptionally smooth and rich and blends beautifully with clean and overdriven guitar sounds.
SPECIFICATIONS ARE BELOW THE PHOTO GALLERY










Genuine Tube Circuitry: 100% vacuum tube and “Raysistor” audio circuitry creates the tremolo effect. The tubes operate at real amp plate voltages at 300V, just like in a vintage tube amp!
Smooth and Deep Tremolo: Advanced pulse shaping capability that replicates either smooth “Bias” tremolo or more intense, choppy neon/photocell tremolo effects.
Turquoise LEDs: Pulsate with modulation speed for visual song tempo matching.
“Dakaware” Knobs: Bakelite Dakaware Chicago 1510 knobs custom manufactured for Effectrode in the U.S.A using the original 1940s molds.
True S-T-E-R-E-O: Link the two tremolos so the sound ping-pongs between left & right outputs or split them for truly independent operation, where the left & right outputs drift in and out of phase.
Rhythmic tremolo patterns with accented beats.
Dithering of LFO waveform shapes for a more randomized tremolo.
Phase control of the two tremolos from 0º-180º
Includes a 12VDC 1.5A Wall-Wart
