November 2012: working on other projects...

December 2012:

The custom made pickups are arrived from Bassculture (http://www.bassculture.de/)

These are twin coil humbuckers (side by side coils) with bar polepieces and neodymium magnets, the tops are made of ebony. Beautiful pickups all over, great craftsmanship and fast turnover time. It's the second time I work with Stephan and certainly not the last one!





The very last updates:
Refining body and neck shape and body-to-neck transition area

[roberthabraken]

Stunning! Looks great! I like the flawless neck carve and its transition areas that are very well shaped.

[T-34]

Thank you for your appreciation, Rob! I am following your build since it was started, you have some great ideas and designs there

There is still some work to do to smooth out rough spots and get rid of tool marks but generally I am rather happy with the result. Now the most important thing is to not to screw it up doing the rest of the work

My next steps will be:
drilling the headstock and installing the tuners (blocking Duesenberg tuners made by Spertzel),
aligning and installing the bridge (5 individual bridges, actually) and the saddle
Installing position dots
Routing pickup cavities
Routing electronics cavities
Last carving adjustments and final sanding
Finishing (with Liberon furniture oil)
Installing electronics

You listed Roasted Ash for the neck of this project. Who was your wood provider for this? I have been curious and blown away by the use of roasted Birdseye maple and now your Roasted ash.

Thanks.

These guys: http://www.dumoulin-bois.fr/ (the site is in french only, sorry)

Looks like the process was first developed and patented in France, we have a little advance on usage here (it is even possible to find furniture, cabinets or shelves made of roasted ash, pine or beech in hobby stores now). The main usage for the wood though is construction, they use it for external panelling as cheaper (and local) alternative to exotic woods.

[T-34]

As I understand it, the process involves "cooking" of the wood in high temperature ovens in the presence of the water vapor...

[SaintMez]

Very nice work!

[pilotjones]

Interesting. and the French site says the process was previously developed in Finland. BTW there's another recent thread about roasted wood on the LC.

[T-34]

Right, the initial research was done in France, then picked up in Finland.


"Ce procédé d’Origine Française, mais développé en Finlande depuis une dizaine d'années consiste à chauffer le bois à haute température dans un four thermique afin de le rendre imputrescible et indéformable. Le but est de préserver le bois contre les attaques d'insectes et d'empêcher les champignons de se développer."

We've had roasted or heat treated wood for over ten years. I made sauna seats of roasted aspen. We have roasted pine for sauna seats as well. At least aspen is brittle and has a lot of small cracks. Roasted birch is used as flooring and it has very similar properties as normal birch, it's just medium brown.

[T-34]

Yes, the initial study was done mid 90-ties I believe.

Anyway, roasted ash just looks gorgeous and added stability won't hurt either

Some updates:

pickup routes




After putting on the bridge and the tuners, couldn't resist the urge to mount the strings

First coat of oil!
Starting to understand why this imbuia top was sold as 5A grade

[SaintMez]

Yeah that top is beautiful! Very nicely done!

[KeithPas]

Wow, not much else I can offer other than to say wow!! Nice work!

[T-34]

Thank you for kind words!

Back to electronics now:

I've reworked the schematics a little, mainly rearranging stuff.
So there will be two volumes, two passive multi-capacitor tone controls "megatone" (more on this later) and one two-channel preamp, or two one-channel preamps if you prefer

Spice schematics:


Testing it on veroboard:

It uses Fairchild BF245C j-Fets and USSR-made MP39B germanium pnp. I'll call this preamp Appolo-Soyouz

Etched and soldered:
