I used Lemon oil on a new neck once. Something REALLY nasty happened to the frets. Scratchy and horrible they were. I have no idea if I left it on too long or what.
If we are discussing the Meatbox, I bought one when they came out. I sold it again. I honestly could not work out how I could use it at gig levels without breaking things.
I have a FI. I HATE messing with software and all that malarky. But that is OK cos there are people who do love that stuff and they put the presets up for easy download. Happy days.
A rewind would probably not break the bank if you are already looking at the outlay of another pickup. And you know you would not need to accommodate a different pickup.
