MockeryBoxLevel connections:
1 input and 2 outputs;
It runs on 9v battery or AC power via adapter.
UTILIZATION
Configuration is very simple. One industry source on the input and the amp or the release or (depending what you want stereo or not).
The control of this effect is via potentiometer 3:
Speed: control the speed / rate of the LFO wave
Depth: control of the amplitude of the modeling
Regen. : Control the input level in effect
SOUND QUALITY
I use it with a guitar JACKSON (single coil pickup) EPIPHONE LUCILLE (humbucker) on a Fender Blues Junior Texas Red. Or an acoustic electric Takamine.

SOUND QUALITY
I use it with a guitar JACKSON (single coil pickup) EPIPHONE LUCILLE (humbucker) on a Fender Blues Junior Texas Red. Or an acoustic electric Takamine.
Used with a clear sound with:
(-) (') (')
Regen speed Depth
This gives a pleasant effect on the sound, a little dreamer
For a more spatial sound is little use the following setting:
(-) (-) (`)
Regen speed Depth
The effect seems to me to correct.
OVERALL OPINION
I have been at least 5 years. I have not tried other pedals of this type.
But I already used emulations Phaser on computer music.
The value for money is good.
It is very solid. The foot control is very good.

The FX20 Phasor was one of the original ten DOD FX-series pedals that debuted in 1982, essentially replacing the Phasor 490 in DOD's product line. Like the 490, the FX20 was a four-stage phasor with four OTA chips, while the FX20 also featured additional circuitry to support silent FET switching. Compared to other phase shifters, the FX20's circuit was more closely related to the Electro-Harmonix Small Stone, which used 3080 OTA chips, rather than the MXR Phase 90 or the Boss PH-1, both of which used FET resistance to vary the phase. The FX20 remained in production until mid-1985, when it was replaced by the FX20B (which featured a six-stage regenerative phase circuit).
