Which low priced transducer would work for under the neck? This of course to pick up the slap sound. I know the k&k clicky is about $65... is anyone using something else that works well? I've been seing some for around $15-$20. I've heard of using drum triggers for this. Ultimately I want to get the whole K&K setup, but right now I'm going to try running both into my Zoom A3. It has a piezo and a mic input with separate controls. I figure I'd probably run the transducer thru a cheap eq to roll off any unwanted frequencies before hitting the preamp. Thank you!
