  1. Than you, I really appreciate your appreciation.

    The wiring: the three upper switches are for the three pickups, up for single coil, ceter is off, down for full humbucker.

    Lower two switches change phase of B and M pickup. So you can e.g. have neck humbucker + bridge single out of phase.

    On the back there is a nice tremolo stabiliser from China, a Blackbox workalike.

  2. Well, after the play test the client wanted better access to the 24th fret, so I extended the cutaways by some 6-10mm, so all the fine carving had to be done again. The same for cutaways, he wanted them much deeper, where I lost my patience with the hand tools and reached for an angle grinder with 60 grit flapdisc. It made the concave shapes much easier to do. Then back to scraper and sandpaper. The body edges are almost sharp in the lower part and gradualy get rounder to where the arm and ribcage touch the upper part. Finaly I got to the oil-waxing, where some not perfectly sanded spots appeared. But it starts looking awsome, if you like natural wood.

  3. Thank you for the replies.

    The fretboard is plain dark ebony from a luthiers eshop in Slovakia,

    A friend of mine made the fretboard on a CNC, we made a test piece of some light brown santos (or whatever species it is, it comes from a crate in which exotic hardwood or veneer is being shipped from overseas).

    The pickups will be Duncan JB Junior. I have 3 bridge pickups branded Framus, hopefully they will play nicely also in the neck and middle position.

    Yesterday we made first test with the client, strung up with one pickup. It plays awsome, as it always does when you plug it in for the first time. Neck profile confirmed, body awaiting more contouring and roundovers, then all the sanding and hardwachsöl finish.

    The crab sign on the back of the headstock was also done on CNC by a friend luthier Michnov Guitars. Look how we bolted it to the machine's baseplate by the headstock. Imagine the torque.

  4. Wormy Birch

    • Very wormy birch core wood, baked in kitchen oven a little, carved top and back contour, hard wachsöl finish
    • 25,5" anigre neck (19-21mm thin C profile) with wipe on nitro + sapele fretboard 12-14" radius with hard oil, dual truss rod in heatshrink tube, bone nut 43mm, ebony side dots
    • Framus Duncan Designed TB-6 and WSC HotRail neck pickup, one volume (hand turned sapele knob), recessed jack in strat position (almost collided with the bridge post, that is why nobody does it like this)
    • Ibanez wraparound bridge with custom brass bushings
    • My fifth build from scratch, hobby builder, attic workshop
    • I wanted to build a double bed of these birch planks I had for a decade in a barn, but I realized the treasured wood is all holes, unusable for furniture. To cure my despair I drew my favourite body outline on the worst piece and started this build. I intended it to be a dirty rough build, well the process was a bit dusty, but at the end the result is quite refined.
    • It plays very nice, very comfortable neck, the sound is firm and crisp, warmer than ash, brighter than alder.

    The workbench photos look the best.

  5. I let the body re-acclimatize for maybe three weeks. Actually the worm holes are completely filled with solid white powder, it is hard to remove. I tried 10Bar compressed air with little success,  had to use steel brush to remove the powder from the surface tunnels. Only the few fly-out holed are emty. Nothing will loosen with vibration.

    BTW it plays like solid wood. And the neck is so nice, comfortable, and no nut buzz even without retainers. The biggest issue was hiding the lenght of pickup cables in the minimal cavities.

  6. I've had some birch planks from a tree my father cut 13 years ago, they are all too wormy now. I made a tele of it some 4 yars ago, since then the worms ate a lot of the remainig wood. Looks so bad I had to try to make something useful of it. A guitar.

    I let it bake in the oven to make sure there are no worms left. The board warped and shrunk a lot.

  7. Wrong. The loose mechanical parts - baseplate, magnet, spacers - cause more microphonics than the coil wire itself. Been there. It will come back to you later when you turn the volume up. Even when you tighten the four little screws and everything is firmly reassembled, it might vibrate and squeel at you.

  8. You are lucky with the cable, most mice have unshielded USB 1 cable. Some cables heve very different power wires and data wires, also not good.

    Now don't forget to remelt the wax by heating the baseplate gently, otherwise it would squeel badly. No neet to dip the whole pickup in wax though.

  9. It is a beauty anyway.

    For the trem routes I usually make templates of MDF scraps, just put them on the body with double stick tape in the shape I need at the moment, no permanent templates.

    Your neck heel is pretty thick still. Consider sloping it towards the neck so that the offset ferrule hole would disappear, then drill a new one. That is how I fixed the same mistake, plus it is a more comfortable neck joint.

  10. Depending on the pickups you might actualy like the wrong value cap, 4,7nF just cuts the treble and keeps more mids. 47nF makes a guitar more muddy. I like 10-22nF.

    BTW it is good to know the colour code or have a chart at hand, mine that I lost was printed on a backside of a local parts shop business card, very practical.
