Tales from my workbench

Recommended Posts

I've spent all of my spare time this past week working on this project. The honey-do list beckons, so I want to get this one wrapped up ASAP... so here are a few photos.

I spent a good deal of time going back over the contours and facets, refining curves, radii, etc. :D




I like to weigh these after I'm done carving and sanding (with no hardware, obviously). This one came in at 6lb., 0.6oz, which is only a few ounces more than the previous 5 string fretless that I made. So I guess the headstock and frets could account for that. :)

Yesterday I began work on the finish, which is Rubio Monocoat over an epoxy sealer. This is the same finish that I used on my last bass build and is a very "close to the wood finish", so wood pores are left exposed (although they are sealed). 

Here are a couple of teaser preview pics. :D





I love the way this finish just makes the wood glow. I should have full shots in a few days. :)

Well, I just finished this one up. Here is a summary of the details...

Scale: 34"
Neck-through contruction: 13 laminates in the main neck beam with dual truss rods, heel adjust
Neck material: Hard maple, padauk, black poplar 
Headstock: Claro walnut burl face with ebony accents
Fretboard: Heart and sap cocobolo
Fretboard radius: 12"
Nut: Stainless zero fret and Tusq nut
Frets: Stainless jumbo
Side position markers: Mother of pearl
Body wings: In order from top to back; Claro walnut burl, black poplar, alder core, black poplar, mahogany, katalox with matched inlaid control cover
Body thickness: 1.5"
Finish: Rubio Monocoat over epoxy seal coat
Tuners: Gotoh Resolite bass tuners, small and medium 510 series guitar tuners
Bridge and tailpiece: Sung Il
Strings: D'Addario Nickel Wound XL .018-.100 
Pickups: 2 Lace 3.5" Bass Bars
Electronics: Aguilar OBP-3 preamp, additional stereo passive output
Electronics layout: Stacked volumes, stacked bass/treble, mid with push/pull select. Coil split switch for each pickup and output jack selection switch (one output from OBP-3, one passive stereo output) 
Weight: 8lb 12oz

It turned out pretty much how I had envisioned it. Surprisingly, the weight is not bad, but of course it is a bit head heavy as all 12 strings are. It plays amazingly well with very low action. I'm still getting used to the technique required and I sometimes struggle to mute all of the strings when necessary.

I think it sounds fantastic. There are a lot of sound options with 2 output jacks. I can bypass the internal preamp and use a stereo cord to run each pickup to separate amps for a cool clean/dirty sound. I couldn't find a way to do this with active output short of installing 2 preamps... :D I'm am including a couple of sound clips. I apologize in advance for the sound quality, my digital interface starting making strange noises and I didn't want to bother with troubleshooting, but I think you'll get the idea. 

Here are some photos and sound clips.


















Of course this one has to be included with a 12 string build. :D

Damn man, that is a serious work of art, and nice demos as well.  Love everything about this build, but for the fact that it isn't being shipped to me.

Thanks, guys, I appreciate it! I'm super happy with this build. It plays so much better than I had hoped for, it's pretty amazing actually. Although, this is the first 12 that I've played, so there's that... :D

😮 what's the string pull on a twelve-string like that one?

According to the rear panel on the pack of strings... 418lbs!!!! 


I can absolutely say that I'm glad I used 2 truss rods. They handle the tension with authority, only tightened about 3/4 of a turn past the point where they were snugged up enough not to rattle.
