1.) I have only seen guts from the smaller (older) Honey (Electra) Psychedelic Machine. Judging from this guts it appears that the basic circuit is indeed only a Univibe and a Super Fuzz.
2.) Even when the pcb in that units has an edge-connector (so no solder work required), nobody took the pcb´s out to show the track side that this can be verified or differences be found.
3.) Also the photos of the (complicated) offboard-wiring I have seen are in a too bad quality to trace them.
4.) As you can see in the differences between the Electra (Honey) and the Companion Psychedelic Machine this offboard-wiring appears to be important for all the possible functions.
5.) The existence of a factory schematic is unknown.
6.) Due to the lack of good enough gut shots this unit hasn´t been traced yet to my knowledge.
7.) If you take your unit apart and make good gut shots from the pcb´s, their track side, the offboard wiring from different angles this unit can be traced. Don´t forget to look from the other side of the chassis below the pcb´s, there are also some components "hidden".
8.) I don´t know about that somebody ever has based a stompbox on this unit.
9.) It could be made into a smaller format, maybe in the size of a Lovetone pedal. A hammond enclosure would be too small because of the many controls. Maybe possible by putting two 1590 boxes side-by-side.
10.) An important question is if it should be a 100% clone or a workalike.
11.) A workalike is easier to make by taking the innards of a Danelectro Chicken Salad and adding a superfuzz circuit and the offboard wiring.
12.) After tracing a schematic, it is possible to decide which functions are not really necessary. By ommiting them the offboard wiring can be reduced.
13.) I would not recommend to use such an unit without an AC-adapter cause a 9V-battery would not last very long due to the power consumption. This should be considered too.
14.) Do you have a screwdriver and a camera ?
