Roland claim faster pitch to midi from the GK5B pickup (new serial connected cable etc) and their Boss GM-800 and/or VG-800
I would have a look at them before going for a GK-3
...but there is still always the physics.
Have a wee look on Vguitar Forum

(Im)patiently waiting for my Stadium XL
from Andertons.
It seems most of us wanted an earlier release, rather than waiting for Showtime to be included.
Now to appear in v1.2
Obviously, check with your doctor, and test it out before the big day if taking this route.
In my case, it was the first time I'd played slide live.
As it was a "Road to Hell" alike solo at the start, I didn't want my hands shaking.
If you're really worried (given the occasion) you could ask your doctor for Beta Blockers ?
Good luck, and try to relax.
Knowing that everyone there will be rooting for you will help.
So sorry about your brother.
What do you call those big, black, triangular Gibson plectrums ?
I haven't used a plectrum for decades, but when I did I liked these.
Haven't seen any recently either.....
