Expanding on the Acoustic Piezo Preamp

inefficiency
Hi guys.

I've been looking for a preamp for my double bass for a long time. Double bass preamps are expensive and it's hard to justify spending a lot of money on my second instrument.

I was planning on building the Acoustic Piezo Preamp on this site and was first of all wondering; Will it work fine with the frequencies present in double bass playing?

Providing it works, I wanted to then add some tonal shaping. Could I just hook the output straight into a baxandall tone stack or similar? Would I have any issues doing this?

Feedback control can also be a big issue with the old bull fiddle and I know a lot of guys use a HPF for getting rid of some of the boomy low end which resonates EVERYTHING and causes issues. Possibly integrating this into the controls or in place of a tone stack would be great.

I've seen a lot of DIY "solutions" for double bass players out there and none of them really hit the mark as far as I'm concerned. I think figuring this out would help a lot of gigging guys out there manage to get their bass heard without it just woofing uncontrollably.

Any assistance would be greatly appreciated.

Cheers guys!

Just to add on to this, a lot of people swear buy this;

It has some stuff in the manual in the DIY section about a "butterworth filter" and some other stuff I don't understand :p.

It might be a good place for inspiration. There is a schematic there, but getting it onto stripboard might be a bit of a nightmare for me to do.
