Hi everyone,
I have very little electronics experience so be nice
I'm trying to build a simple acoustic stomp box which takes an audio signal from a small piezo transducer, filters out all the high frequencies above say 150Hz and sends the output to a auido jack which is plugged into an amp. It's a simple device to replicate a bass drum sound commonly used in blues. (The transducer sits on the wall inside a hollow wooden box to amplify the sound of a foot taping on it)
The circuit below seems to be what I'm after however my limited knowledge of this stuff has me stumped on a few (read most) things:
1. What does the circle represent?
2. Where exactly I would wire in the transducer and jack output? I'm guesing they sit in paralell with the unknown component but am not 100%.
3. Would this need to be powered at all?
4. If I wanted to adjust the cut-off to 150Hz what changes would I make.
This probably seems pretty basic for you guys, sorry. Any diagrams (layman or otherwise) would be helpful.
Thanks in advance!
