Spring Drone

[Dminner]

An instrument and not a pedal, but...there is a circuit in there.

Two piezos with individual vol and tone control. One runs clean and straight to the input, the other goes through and Electra distortion circuit. Can run either separately or both in parallel. The distortion channel is great at adding feedback and when ran in parallel the feedback is tamed but all the grit and distortion is retained

Wow.

Cool, play it with a violin bow.

If you don't already have this book you should.

It's crazy inspiring.

Spiffy! ... I wanna hear it.

That is very neat looking and a cool idea.

great build. So, you just pluck the springs and pick up the vibrations with the piezzos? Is there any signal amplification involved for the clean path? No idea how much signal a piezzo pickup is producing, but piezzo signals in general are really low for small lateral changes

No amplification at all for the clean side. Not just the springs you can tap on the enclosure for drum sounds as well . Lots of sounds. Taping, scrapping and hiting springs. I need to swap the biggest spring out though, there is not
Enough tension on that one.

The piezos are fairly larger. Like 1.5" I heard the larger the piezo the less need for amplification.

This is so damn cool. Can we please have a demo?
