Hey everyone, I have an ESP LTD EC-1000 Deluxe. I want to swap out the EMG 81 bridge pup for a Gibson 57 Classic pickup. I know how to solder from tinkering with video game cartridges and just messing around with spare pickups in the past. I have always been able to get it right the first time. I do not, however, have actual knowledge about the electronic components involved with swapping pickups (pots, capacitors, pickups, etc.). I just read the installation instructions 10 times over, and do it piece by piece like a color-by-number. A few questions for the seasoned tinker'ers: 1. Is it difficult to swap out an active pickup for a passive one? 2. Do I need to change a lot in the wiring to prepare for the swap, or is it pretty much de-soldering one and putting in another? 3. Do I need to change the pots? I don't know what value the current pots are (googling for the specs of this guitar doesn't give me the information either). 4. Is it a pretty bad idea for me to attempt this on my own? I have swapped out a few humbuckers in the past by just following the included paper instructions, and I've gotten it right every time so far. 5. The Gibson 57 pickup comes in 2-wire and 4-wire formats. I think I need the 2-wire one. Is this right? 6. At some point, I would like to swap out the EMG 60 neck pup for a (get ready for it) Telecaster neck pickup. I was thinking I might be able to velcro it in place, since the humbucker slot is so much wider than a Tele slot. I don't mind if it looks strange. I just want to know if it's possible on this guitar. Thank you for your help. Cheers!
