I got a large cookie tin from my mother in law(4" x 12" x 9") and decided to do a resonator bass without frets.
Thinking about using a Uke type strip Piezo, P Bass Pickups, 3-way switch, 250k volume and tone pots with a .047uf cap. Was thinking of using regular Bass strings for 4 string bass.
Using some square table legs(2 & 1/4" x 1 & 3/4" x 21") for the neck - bolted to a through the tin piece. The through the tin piece will have a hollowed out area at the end for side mounted tuners of some kind, may get actual tuners - may make something. The string ends will mount at the nut end of the neck like a Steinberger Bass.
I'm going for 30" scale. will use a brass bolt for the nut and a steel bolt for the bridge with the strip piezo under the bridge and the Pbass pups close to the neck.
These table legs being 2 & 1/4" wide are making me rethink my plans. A BassVI is really starting to nag at me. Maybe a set of 12 gauge strings and a 28" scale instead of the 30" scale. If I go that route I will have to rethink the pickups, Humbucker(coil tapped) in the bridge, strip piezo under the bridge and a P90 in the neck with 3 on/off toggles and 3 separate volumes?
I decided to stick with the regular fretless bass idea, but will be 5 strings instead of 4. Not sure on scale yet, going back and forth between 28" and 30" scales.
Thinking of doing a low impedance pickup like the ones that Wayfinder and Buggy have made. Might also add some J Bass pups, Rondo has a set for 19 bucks.
Started work on the neck yesterday. Cut a channel for the 1/4" square steel non-adjustable trussrod. I usually glue them in to stop rattle from occurring, Had one guitar neck develop a bad back bow when I glued the rod in, so this time I stuffed tooth picks on each side to keep it steady and from rattling.
Then I started forming the back side. First I trimmed the edge with a 1/2" roundover bit in my router. Then I use a 1/2 round rasp file(round on one side flat on the other), utility knife blades(used as scrapers) and sandpaper. Got one side mostly done, should be completely done with the neck in a couple days.
For some reason my last pics and post ended up on the comment wall.
