errrm well there isn't much point in me buying one, as you probably know I have been talking to you about a build
lower impedance to perform better with long cables / signal path basically
I don't desire a tonal change really
That sort of thing is so tone-nazi that it's not worth hacking a hole in your guitar. Honestly - If you want a clear signal through your leads - Then buy better leads.
If you've got a cr@p lead - lowering your impedance won't help.
Once you've got a £200 lead and still don't think it's good enough then hack a hole in your guitar.
But honestly - Guitars aren't meant to have piano tone - If you distill your tone you lose the essence of the guitar.
