I've just finished my DIY snare, and it is horrible..... I'm not sure what's going on, or how to begin to troubleshoot. The snare only responds when I hit the foam directly on top. No input from around the cone gives any kind of signal to the module. I followed the diagram Beatnik posted, and wired it up like that. I looked at the thread about the snare mis-triggering moving from TD9 to TD30, and I've taken notes from there; I will be trying those steps, but I have more generalized questions that might let me know if I did something incredibly wrong.
The snare is a 14" steel snare, 6 lug. It's just a cheap snare I got off of Craigslist. Is metal okay to use with the electronic drum? Does it cause some weird issues I'm not thinking about? Could it be grounding the jack and shorting it out? I used a 12" wooden tom that I cut in half and they work great.
The trigger system I'm using is similar to the RTS trigger system that I built myself. Working just fine in the toms, not so much in the snare. The piezo's are 27mm for both rim and head, but I don't seem to get any response from the rim at all. I know they work outside of the shell, if I thump the piezo a little bit I get really good response, but again, that's direct contact with the piezo. I've got a TD-11k that I've turned the sensitivity all the way up, turned the pad types to different types, nothing seems to help. I'm so ready to be done with this build, could anybody please help me figure out what I did wrong, I just want to bang on the drum!!
