Gough Electronics:
Tremolo, Vibrato, 2, 3 and 4 stage phase plus resonant 4 stage.
Modulation modes:
normal sweep: like any phaser
envelope up with added sweep (same as Filtron)
envelope controlled sweep speed (the louder you play, the faster it sweeps)
Dual Sweep: two sweeps at the same time to give a random effect. gives a great pitch warble on slow setting with vibrato
delayed effect: effect is off each time a string is played then fades in afterwards - nice for vibrato
Frequency modulated sweep speed: the effect gradually speeds up and down again continuously like a leslie cabinet. FM rate is adjustable, as is the maximum sweep rate.
Gough Electronics:
Here is a description of the controls.
Mode: This control selects the effect to be used.
Tremolo: varies the amplitude of the guitar sound, use a high setting of the DEPTH.
Vibrato: varies the pitch of the guitar sound, use a low setting of the DEPTH.
2 stage phasing: gives 180 degree shift - Like MXR Phase 45.
3 stage phasing: gives 270 degree shift, not generally used on other pedals, produces a nice subtractive phase sound, like a high pass filter.
4 stage phasing: gives 360 degrees shift - Like MXR Phase 90.
4 stage with resonance: feedback around the phasing circuit emphasises the phase sound - almost like a wah pedal. Great when using ENV modulation.
Modulation: This selects how the phaser controls the phase sound.
ENV: The amplitude or loudness of the guitar (envelope) controls the sweep. The phaser sweeps higher, the louder you play. When the SPEED control is set to ENV, only the guitar envelope is present. At any other setting of the SPEED control, the low frequency oscillator sweep (LFO) is added at a rate set by the SPEED control. The DEPTH control affects the envelope amplitude.
ENV RATE: The guitar envelope controls the speed of the LFO. The louder you play the faster the LFO sweeps. The SPEED control acts as a sensitivity control for the guitar. Turning it clockwise makes the LFO speed up faster. The DEPTH conrtols affects the LFO amplitude.
LFO: A standard vintage phaser sound. The SPEED control alters the LFO speed.
DUAL LFO: Two LFOs, one faster than the other, drifting in phase cause a random sweep effect. The SPEED control alters the speed of both LFOs.
FM LFO: A second, slower LFO, the speed of which is controlled by the position of the MODULATION control within the marked area, rhythmically alters the speed of the first LFO. This frequency modulation gives a sound similar to a that of a Leslie rotating speaker speeding up and slowing down. The SPEED control sets the first LFO range - clockwise gives a faster 'upper end' LFO speed.
DELAYED LFO: This is like the standard LFO setting but with delayed onset. Each time a string or chord is played (above a certain threshold) the effect stops and the gradually fades back in.
Depth: This control always sets the sweep range or amplitude of the LFO, except in the ENV mode, when it acts as a sensitivity / range control for the guitar envelope.
The range of this control is very wide.
