heres a common tele mod for player who need the tele sound, sticking with the single coil in both bridge and neck plus having another 1 more pickup config(both single coil in series to get a pseudo humbucker sound).
If you add another push pull pot, you can have another 1 more pickup config(bridge pickup our of phase with neck pickup in series or vice versa)
total, 5 different pickup configuration from tele(3 stock plus 2 extra). Much cheaper than changing pickups and having extra sound in it
