Excellent condition Spaceman Effects Delta II Harmonic Tremolo. Pedal only.

Delta II is a powerful optical harmonic tremolo with extensive tone shaping and an all analog signal path. Its novel dual LFO design enables its pilot to craft a range of harmonic, and traditional tremolo sounds that stagger, hop, buzz, ripple, and swirl with unparalleled variety using its simple control panel. Soar through the sonic scenery as evolving rhythms throb and pulse through your consciousness like stars flickering across the cosmos.

Delta II is an analog harmonic tremolo, with smooth organic tone. Harmonic tremolo is achieved by splitting the input signal into high and low frequency bands, and amplitude modulating them in opposite directions. As the low frequencies pass, the highs are cut, and as the highs fade back into the mix, the lows sink below the horizon. Since one of the frequency bands is always passing, it's less choppy than typical for trem.

Using Delta II's innovative LAG control allows you to adjust the offset of the dual LFO's, morphing from traditional tremolo to rich harmonic tremolo; and most notably, all of the in-between states as well. Combined with the pedal's unique VOICE feature, this makes for great swirling, phasey tones with endless rhythmic possibilities.

YOUR HARMONIC HEARTBEAT

The Delta II features a high headroom all analog signal path with expanded tone shaping features. The input signal is buffered, and then flows into a 2-pole state-variable filter to perform the frequency range split. The high-pass and low-pass filter outputs, along with the dry signal are routed into the tremolo portion of the circuit. The optical elements in the Delta II make for a smooth rise and decay, with a natural response.

Exploration of the DEPTH, FREQ, and RES controls will unearth filtery stabs, slithering vibrato, or robotic rhythms. Volume is set from our shop to unity gain when the effect is engaged, but may be fine tuned via the internal trimpot. Each portion of the Delta II is carefully thought out, and painstakingly executed to be beautifully colored and alive with rhythmic intensity, and effortless shimmer.

Additionally, the extremely useful VOICE toggle offers three signal path modulation options. High & Dry - highlights top-end shimmer, and emphasises clarity and bite. High & Low - provides a more liquid tonality especially useful for swirling phasey sounds. Low & Dry - excels at dark throbbing low-end presence.

in and out of time

The LFO of the Delta II is deceptively simple, yet surprisingly versatile. The dual output triangle wave oscillator has a unique ability - Lag. This allows the outputs of the LFO to smoothly lag from 0-180 degrees out of phase while still being in time. What this means is that with LAG control at minimum the two LFO outputs are identical, and at maximum LAG, they alternate in opposing fashion. For traditional tremolo sounds, keep the LAG at minimum, then as you introduce LAG, the LFO outputs diverge, creating infinite shades of harmonic tremolo up to maximum. The middle ranges of this control can thump, pulse, beat, bunnyhop, stagger, and dance in any given instance. For even more temporal animation, LFO RATE or DEPTH may be modulated via expression or CV.
