I replied back to you, but you obviously haven't seen it. Would be very helpful if you could re-read the message on what I'm attempting as all you did was correct something I specifically wasn't doing.
Original question (with highlight)
I own a JTV-59. And I'm seriously considering a transplant I don't believe has been attempted.
I also own an Artist 8 string guitar. Very cheap instrument that punches way above it's weight. 26.5 scale.
So here comes the crazy. Can I make 1 instrument to rule them all?
My plan would be to buy a Floyd Rose 8 string tremolo (https://floydrose.com/products/frt8?variant=29879554962)
Then change the first 6 saddles only to graphtech (https://graphtech.com/collections/ghost-pickup-systems-guitar-saddle/products/ghost-floyd-rose-saddles-set-6-string-pn-0080-x6?variant=29500005449751)
From there route in and mount the JTV-59 Electronics.
And finally replace the pickups within the 6-8Kohm range (if that's right) with these (https://www.dimarzio.com/pickups/8-string/paf-8).
To clarify, I would only be using the piezos on the 6 upper strings. I don't expect (nor intend to use) any string functionality in the lower 2 strings in anything but magnetic mode. Hope that changes things. The main purpose of this is to simply have my 8 string be a variax for tuning purposes over the 6 strings it normally occupies.
My main concerns are (a) K-ohm pickup compatibility of the replacement pickups I linked above (b) any weird circuitry that would not pass the 2 low strings through as magnetics.
Thank you for the assistance.
Doing just the first six only would work from a hardware point. From a software point, it should function, so long as it is a fix bridge and not a tremolo bridge (the 59 program can't handle tremolo bridges). I take it you are keeping it a fixed bridge.
Be aware of warbling in model mode, when setting the pick-up heights. The mag signal will be cut-off, but the mag field will still pull on the strings, as they are permanent magnets.
Di Marzios are in the correct impedance range. You're good there.
