Welcome Zulu and Congrats on the Detonator. Excellent guitars. I've ended up with 6 Detonators over the past 20 or so years. Mine all have the Dimarzio passive pickups that were standard. Mine all have the Guild/Mueller bridge and the trem/vibrato arms are press-in style. The Sperzel locking tuners were standard issue. Earlier Detonators (like below s/n 100050) did not have a push/pull tone pot to split the coil of the bridge humbucker. After around #50 the tone control was also a push/pull coil cut. Earlier ones also only said Guild on the headstock. I don't have any experience with the EMG pickups option. Very well built guitars. Have fun with it. -tonepoet
