Doing Things Wrong

Electronics - Piezo

Projects utilizing piezo pickups and electronics.


This is the biggest of the Audiovoxes, weighing in at a full 12 pounds, with a 36" scale. The neck is a Brazilian Cherry (Jatoba) floorboard over maple, with a straight cutout headstock. There are over 100 marker dots. The body is veneered masonite over solid plywood, with Danelectro-style Tolex binding. There are also strap buttons, this instrument can be played vertically or horizontally.


This one is almost identical in construction to the Danelectro-style - masonite over chambered plywood body, masonite pickguard. The neck is purpleheart over maple, with plastic fret lines. The soundhole merely serves as a pickup mount, and the pickup was just insurance against never getting the intended piezo system to work. Eventually, I did get it to work, the piezo is incorporated in a modified bridge, and sounds great. 30" scale.


This bass is a 21" scale, with a piezo saddle mounted in an adjustable bridge. The soundhole is just for looks. The strings are metal-wound Kalas. The fretboard is cut out of the ugliest piece of wood I ever received. For such a small neck, I managed to cut around most of the ugly, and the result isn't half bad.


Built as a testbed for a number of ideas:

Don't get caught in prison with one of these​

After making a muddle of things with a razor blade and several other implements that proved to be less than satisfactory, I decided I needed to have the right tool - something roughly pencil-sized that can be handled with precision and ease, with a proper scraper edge. I took a look at StewMac, and found their binding scraper - exactly what I was thinking of. But with shipping, it would cost $15, and I'd have to wait a week for it, and after all, it's just a piece of steel. So I started thinking and remembered I have some 1/2" steel binding strap material. This is the stuff that is used around very large heavy boxes. It is a fairly hard and springy type of steel that would probably make a good tool. So I got busy in the shop and made three scrapers.
