I have a couple questions regarding different customizing/modding options on a guitar.

How hard is it to coil tap a pickup?

How do you turn active electronics into passive electronics (for ex. in a Charvel Model 4/6)?

How do you go about switching 3 toggle switches into a 5-way selector (once again, using the Charvel Model 4/6 as an example)... and wouldn't this leave holes from the previous toggle switches being there? (There's 2 of these guitars on ebay with this mod if you wanna take a look as an example).

How much would it cost to get these things done if they can't be done without 'expert' experience?

Thanks in advance!
