I have a drumset that uses a piezo sensor for it's pads. I would like to create a gain circuit that will boost the piezo signal.
There was a message board where this was built and working but the schematics were gone, but it's just a simple non-inverting amplifier.

I'm using an LM358N and I cannot for the life of me get it to work properly.
I tried a couple configurations on a breadboard then just started playing around in multisim with a 555 timer circuit because I still can't get this to double the output signal.
I've been told it needs a dual rail power supply but can work on a single polarity PSU if I use a bootstrap circuit and DC blocking caps....but where do I connect them? what are they?
The guy who originally did this didn't seem to have a bunch of extra parts, and used USB 5V power.
I need something simple, and quick using an LM358 to boost the output signal of a piezo sensor.
