Doing Things Wrong

Audiovox 736 Bass (2/4)

The Start

  • 1-3/4" solid walnut ( laminated from two 7/8" boards ) 
  • body scaled up about 5%, with 3/8" round-overs
  • Fender standard neck pocket
  • first coat of clear danish oil

This is not meant to be an accurate reproduction. It is going to be thoroughly modern and playable, with a 32" 20-fret Fender-type neck with truss rod, sealed bass tuners, intonating bridge, and modern pickup and electronics.

The body is now all drilled & routed ( actually, Forstner bit on the drill press, just the way Tutmarc did it. Walnut shavings everywhere. ) Took a lot of coats of Dan oil to fill all the walnut pores, now just needs final finishing. Output jack will be on the side. The neck attachment is bolt-on ferrules.

The pickguard is 90% finished, still covered with masking tape, aged pearl. That is a concentric knob, this bass will have a tone control, and maybe a tiny pickup switch if it turns out to be useful. The pickup is in the historic place, but the knob is moved out of the way a bit. I have my regrets about the bridge, but I made a shim for it, and it should work out. Kind of rounded, like the original.

The pickup I have for this is a blade-style strat humbucker. Say what? A pickup is a pickup. The only problem I can foresee is that it is a bit narrow for the string spread. If the E and G are weak, I have already routed for a lipstick pickup. I'll bet the guitar pickup works though, and will sound just fine. Or at least as good as Tutmarc's horseshoe magnet contraption ( which was brilliant in its day. )

The neck is patterned on a Precision that I had handy, but 32" scale. Stewmac fretboard, cut down; masking tape has the layout for the dot markers. The 20th fret hangs over, a design I worked out that allows you to build a 32" neck that is a drop-in replacement for a 34", with no modifications to the body. Or in this case, if I wanted, I could bolt on a 34" off-the-shelf neck. The tuners will be compact sealed Gotohs, and each will have a nearly straight string pull. I leave it to you to figure out how that is going to work.

I think that's about it. Next report will be when finished.

This is my favorite truss rod design. It is not my most advanced, but it is the simplest to build. Although it is a single-acting rod, a little forethought in routing the channel makes it reversible, effectively double-acting. That requires some disassembly of the guitar, but you only need to change the direction of the rod once or twice in the life of an instrument, until it settles in to a mature shape.
