This is a pedal for guitar (analog transistor with truebypass), one input and two outputs 6.35mm (left output = mono).
Super sturdy construction.
Powered by 9V transformer not supplied, or battery.
1 foot switch to bypass entrenched and 3 knobs to adjust the housing Rate, Depth and Intensity (Speed, Depth and Effect Level).

Using extremely simple.
The manual does not make you an intellectual bilingual (English / German). All technical specifications are, perhaps an illustration to show how pressing the foot-switch with his foot, and two picks come with pedal unfortunately work with any of my keyboard is missing.
Chorus quite "Glasnost", the modulation possibilities range from "subtle" to "very audible and very fast."
I use it on an old organ GEM without chorus, the G50, which is similar to this model: https://fr.audiofanzine.com/orgue/gem-electronique/G8-PCM/
This modulation is missing from this machine! Insert in the output of the organ, I retain its nature the instrument if the 3 knobs are at minimum (without turning the truebypass so), and all of it's dance background those old transistors!
Used for 2 weeks, I will inform you in case of sudden death or rapid degradation of the sound quality of the object.
The Q / P ratio is excellent for those seeking a chorus modulation without coloring.
Analog stereo chorus with true bypass and three settings (intensity, depth, speed).
The metal box is a little big but it's really tough.
It's really piece of cake. One branch, turn knobs and presto. There must have been a manual, but it is not necessary.
Very transparent, it's a nice chorus. Simple and effective I think he can adapt wherever the need arises a chorus. I use it with a Godin Freeway, a hall of fame and a VOX amp AC4TV mini or a Marshall JCM.
I actually use a fairly discreet (no chorus that nauseous although it is possible). It's the little extra that sublime arpeggios. Really top quality, I do not see what you can expect more of a chorus but I confess I am not an expert in chorus.
Maybe some demanding (and it should be) who likes vintage sounds repprocheront him not to be particularly warm or soft. It is very clear for me the color and warmth come from the amp.
I use it for four months. For me this is not the effect to be noticed too, it just denser sound, makes it more singing. To do this little box at Palmer (who has cracked Christophe Godin for that matter) is perfect.
Before I had a Tonelab LE and its chorus that I found nice. If that is simpler, there is not as many styles as possible chorus, just the basic one but it does it well, with more transparency than the Tonelab and widely enough for me.
Everything is good and more for a really nice price. With the experience I would do without this choice to look elsewhere.
