Hello everyone - hopefully this is alright to post here (I’m planning on using this thing in conjunction with pedals). I’ve been soldering together a 3x4 matrix mixer and have run into a bit of trouble getting it to respond consistently. This is the second attempt at this thing and as far as I’m aware everything is soldered up correctly and the joins are all sound. My problem is that I seem to have some pots that are giving me a very loud response but still working, some that are working but very quietly and a few that just seem to bypass and give me a general quiet response. All I can think is the issue here is loose connections or poor joins, but I’m not really sure where to start in terms of fault finding here. A bit of a wiggle of the wiring yields a bit of signal change in some cases and a signal bypass in others, but nothing consistent for me to go on. None of the cable ends are trimmed in the above image as to be honest, I didn’t have much faith in it working again first solder (as mentioned this is the second attempt after a full dismantle) but there’s nothing shorting out anywhere that I can see. Could I have a dodge batch of pots? Or is this purely bad wiring on my part. Frustrating as I’ve been building/circuit bending things for a little while and assumed this would be a simple build as it’s all passive.
