Hey All, finally got my Electrovibe all populated, may have boxed it too soon. Pardon the flux, I'm having a hell of a time getting it all off of this one for some reason, i've washed, scrubbed and dabbed enough times that the ISO appears to have pulled some red coloring off of the chorus/vibrato switch.
The bulb flashes and adjusts with the trimmers exactly as I've had them do on previous vibe builds. I used the pedalpcb pot insulators for the speed pots. The enclosure holes for these two controls were off by the tiniest bit, causing them to lean back a bit and pull back on the lower row of pins. However, I made sure with a mini screwdriver that they were making good contact with the pads before soldering over them. In the attached pic, they look thirsty because I wicked up some of the solder to double check again that those were making contact, planning to reflow them when I get a better idea of what's wrong. It's possible there's some kind of short underneath, but i doubt it would be affecting both speed controls the same way if that were it. After this pic i adjusted the left pot, lower row right side pin with fresh solder so that it was touching and no change.
I get bypass, LEDs, etc but when I engage this effect the only thing I get is a volume drop and a slight tone shift. The volume control does work, but I have to keep it maxed to hear anything. Speed footswitch does nothing other than turn the indicator on and off, the chorus/vibrato switch only adds a little volume back when switched to chorus. I'm going to replace the stock R4 with a 2.2m as I've seen in other threads here for the volume drop. If nothing jumps out from the pic below regarding the lack of vibrato, i'll update when I have a chance to inspect and take pics of the underside.
