Yeah so i have an ibanez xiphos. it is possibly the best guitar i've ever played and i've played a lot of guitars. well i can tell you its perfect. great low action, great feel, great sound but one thing id like to improve is the pickups! they are USA dimarzio d'activators. i want to swap em out for Dave Mustaine Signature Live Wire pickups (18 volt) or Seymour Duncan Blackouts (18 volt as well) Besides cutting into the guitar in back for room for the batteries and what not would it make any difference to the guitar? Today someone at sam ash told me it would mess up the sound and i'm better off just putting EMG's in it. See my plan was to come really early both days of gigantour in my city and get my back plate signed by Dave Mustaine. and then getting Dave mustaine pickups which kick *** all on their own. and it would be like a Mustaine signature Ibanez Xiphos. Probably wouldn't sell for as much as i would pay for all that but i'd probably never sell it. Help/ Tips please!
