Hey Jazzy ..how are you my friend?
I installed Red fret FX on Bonnie!
There was no problem in taking her by the neck or whatever. It's spectacular for the audience (hey dude ...are you playing a runway?

) because the LEDs are ON the side of the neck ...instead of IN the side of the neck when installed by construction.
HOWEVER!
I cracked the set by ...adjusting the nut of Bonnie!
I was not careful enough and the contacts broke when trying to adjust my nut height because the wire from the battery to the LED-ribbon is JUS in a critical point there!
So ...no Bonnie with red lights anymore.
Fragile ...yes!
Handy ...absolutely but ...BE CAREFUL!!!!!
For normal budgeted players it is not a big cost though!
Good luck!
