get an even natural sounding response.
There are a few options.
- The stereo jack OP with separate feed from each piezo is a good way to go
I don't think using a 1M passive potentiometer level control after each is the
best idea, depending on the OP level, the pot could introduce significant noise
purely due to the high value of resistance (Johnson noise) and the piezo
really wants to see a very high impedance for best sound. IME, an
active buffer fed directly from the piezo will give the best results.
- Another option is to make a dual active buffer + level control in a tiny box
with a single 9V battery. This can be mounted to the Bass with velcro etc.
FWIW, I've usually obtained best results using just 1 piezo and play with
the mounting location. How and where is your Piezo attached to the bass?
This makes a massive difference to the sound.
