I hve just bought a set of Fender Vintage Pickups and will be coupling them with a Sad Onbaord Pre-amp.... But i had a Crazy thought last nite....!! Is it possbile to install two sets of Jazz Pups effectivly making two MM style pickups and have a swtich to swtich between.. Set 1 Set 2 Both Sets Giving an interesting and unique sound.. This would give me bassically a Bongo type config with the twin MM's that you can swtich between the coils.. Also.. can someone please tell me wot Double and single coil tapping means.... If a manufacture has already done this could you point me in the right direction I seem to remember the Peavey T40 had this config....??... Cheers peeps..
