Ha, sorry, no joke intended ! I'm an experimenter at heart and the results have been pretty good to date . Nothing ventured etc.
I play a lot of "behind the slide" chords on electric resonators and often the triads are a wee bit sour intonation wise , slanting the biscuit etc doesn't help enough and I don't have time to re-tune to suit each song ..
To get ‘perfect ‘ intonation on a Reso ( when fretting) some compromise will have to be made. It is probable that the best tone/sound will come from a straight,narrow bridge. To get intonation ‘ perfect ‘ the saddle will need to be 4-6mm depending on your strings . I suppose you could use the Tune-a-Matic as a guide to get the desired intonation points ,then make a wider than normal box/maple saddle, with a wider than normal slot in the biscuit, keeping the Gibson style bridge would be silly and a clumsy fix to get your intonation right.
Professional reso players have been playing without this luxury ( or abomination , depending on your point of view) for 90years .
Having said that, bramley, I know plays a long necked reso, so fretting behind the slide ,often above the 12 fret is something he wants to do in tune. A long necked Reso-electric will already have a compromised tone ( usually a very thin body etc. ) so in this case it may be something to consider, but for a 12 fret to the body it is probably a step too far.
My own long necked reso has a 4mm saddle filed to give compensation to the plain G and I am very happy with the intonation ( though I rarely fret behind the slide) . Would it sound ‘better’ with a standard saddle, probably, would it play as ‘in tune’ above the 12th fret probably not. Life is full of compromises and this is one I am prepared to live with. Have I put 4-6mm saddles on any 12 or 14 fret guitars? No. Pete
I see the same thing that Gaucho commented on- the weight. Another factor to consider IMHO is the strings positions woud not be adjiustable horizontally with it and it looks like they extend beyond the traditional biscuit. H
All cone, and no external mic... The DI sound is a CB radio type dynamic mic element ( often used in DIY harp mics) mounted under the cover plate , the magnetic p/up isn't doing much besides sending to reverb at the mixer.
