Howdy folks,
As I've moved on to other testing and troubleshooting for the nifty Electrovibe I'm running into some new problems. Namely, the "intensity" of the vibrato and chorus are basically not present. I have followed the DK Pedals tweaking method (here) and the Madbean Pedal Harbinger (here, pg 7). Alas, all to no avail. Also, the output in vibrato mode is VERY quiet, even with the volume at max.
I have output in all modes, bypass and when the pedal is engaged. Just barely to no effect and some other oddities.
The vibrato effect is there but not much intensity even when maxed and the chorus is basically non-existent. I've undertaken some additional troubleshooting and measured all of the pots. The speed and volume pots, while not 100% to their stated values all measured within 10kOhms of the stated values. The C100k dual gang pots on the other hand were unusual.
As soldered onto the board, measuring the wiper (middle) lug to ground, I only showed ~ 4k6 Kohms on the adjustment. Taking it to min-max only took it to 4K8. This was true for both intensity pots. So, I figured maybe bad pots? I pulled them out of the board and measured them. One measured at 99k and the other at 89k.
I don't have a schematic for this so I have no idea how to identify if those values on the board are normal or not. Any thoughts on where to go next?
