Not the best tricone ever, but better than the Eko before I started. I'll make a cover and stick a pickup on it, but I may not make an other PT What would in sound like with 2 resistors at the front and 1 behind? Could someone make one and let me know?

Hi Pete,
I think you are being unkind to yourself. I think that guitar actually sounds quite good. Good sustain, good bass on the wound strings, good balance overall.
Of course, it might sound crap in person, but it sounds fine on your video !!

It might be an interesting research project, if you are so equipped, to attach a piezo to each leg of the spider and look at the signal, versus each leg on a standard tricone. If your guitar is lacking bass, that will possibly show up. Also perhaps the symmetry of your design may lead to cancellation of some sound. They are speaker cones essentially.

Yes Fred, That sort of thing should be done. The best people would be NRP, they have bodies, wells and necks around the place, and new models are the life blood of any large company. So far they have not really done anything very new, there are those that think the best 20s/30s Nationals can`t be improved on (MM ?) But if you don`t try you don`t know. PT Can National now post a video of their R&D dept. where different cones/formats are tried out?

Pete, I commend you on your skills and interest. You are quite a talented guy. Maybe there is a way to further improve the Y saddle. If you were not aware, Don Young is quite accessible via email at his new shop Dons String Shop. Maybe would be interesting to run a few questions by him.

with that in mind, perhaps a fixed pivot point between strings 3 and 4 with the bass trio going to a large(r) diameter cone, and the treble trio going to the small(er) diameter cone.
kinda like the woofer/tweeter blend in a hi-fi cabinet.
the tricky part would be determining the length of each arm and location of the cone centers from the pivot to fine tune the pre-load pressures on each cone and balance out the tone and volume response between the two.

This is just the sort of thing NRP should be doing. It may not lead to a `better` reso. but it may be a new sound could come out of it, just as the Dobro was a major rethinking of the National. I am not skilled enough (or have the right bits around my workshop) but there must be an NRP worker who could be given a couple of (dented or scratched) bodies to play with? PT

Mitch... Just for the record I have no basis to suggest there is any phase cancellation other than conjecture... I do think you are onto something by suggesting trying to segment the saddle/bridge in some what and direct the bass and treble frequencies to the appropriate cones.
While on this subject, I thought a great giant leap backward for guitar amp technology would be to replace the traditional speaker with an aluminum cone (not a Hartke) that would be driven in a way to make any guitar sound like an acoustic resonator... Maybe I'll take the idea to shark tank...

Pete. Very nice.
Can you tell me what grit you use for finish sanding prior to lacquering? I am thinking there must be some roughness for proper adhesion.
Does anyone know what grit us used on steel bodies?

The 'flame' effect was got by using an orbital sander with 250grit. It helps to hide small bumps/dips.. If I wanted a shiny finish I would go down to 1000/1300 and then buff. This would be a lot of hard work, so is not often seen on my guitars! PT

Here is a close-up ,so you can see how rough it is. From a few feet away I love the look of it. PT
