So I got my set last week and put them into my Al D. this past weekend.
For starters, the screws that come with the pickups are too short to use in the Al D - not sure about other models. This would have been useful to know before I mounted and soldered them. Even with the screws barely threaded the pickups are too high for the strings to clear the pickup. I used the screws that were in there previously from the DGT pickups that the PTC had installed for me. There is not a lot of wiggle room here for height adjustment - they sit pretty high with just minimal turns of the screw. I wanted to use longer screws to get them a bit lower but that would have involved drilling some wood away for the screws to clear.
On my bench I just have a little smokey amp and I could tell right away that these things are hot! We had weekend plans so I didn't get to put the guitar through it's paces until Monday at rehearsal. My immediate impression was good - lots of balls, plenty of clarity, and lots of output. Tapped the pickups are a tad too bright for my tastes. Rolling back the volume control resulted in tone that was too bright as well - a bit piercing really. If they're going to stay in the guitar I'm going to need to change the treble bleed Since they're hot you have to roll back the volume a lot before it makes much difference and cleans up (which was expected).
The worst part of all was that I didn't realize that the treble/bass pickups use different color coding for the wires so the way I wired it the middle position is out of phase. Sigh.
I'm on the fence about these pickups at the moment. I need to fix the pickup phase, fix the high-end when the volume is rolled back, and I'd really like to be able to lower the bridge pickup a little but there's barely any room to do so.
