I traded a guitar to a dude for a whole bunch of pickups (air norton s, injector, tone zone, duncan distortion, emg 81 and a Dimarzio PAF 7) and I ended up throwing the PAF 7 into my old RG7321 (my first ever 7 string I keep around for sentimental reasons). I gotta say, I fucking love this pickup and is making me consider getting a 7 string or two to fuck around on and use a bit more.
I ripped out the old blackouts in it and sold them off and it was sitting on my rack un used. I was going to direct mount the pickup with some #2 screws but getting them was a hassle and me being me, I can get impatient. So I cut up an old 6 string pickup ring, used the two outside edges and screwed that into the body to mount the pickup without drilling out the pickup. Tossed on some strings, wired it direct to the pot and disconnected the tone pot (I'm outta rotary switches or else this would get one too) and plugged it into my rig.
It sounded like I had hoped all my other 7 string pickups would sound like; a 6 string tone with extension down to the B. All other ones were dull and focussed too much on the low end. The PAF 7 brings that classic high end sizzle to the low B that I can make use of. Also when I roll off the volume it cleans up very nicely, even in my diode clipped MP-1. It has a nicely pronounced midrange that sits at just the right point for attack without getting thuddy. Thrown onto a clean channel it sounds full and rich with no overly boomy notes when doing extended 7 note chords.
It's got dynamics which is nice and even on a dark sounding rig like my Mesa, it still had clarity. With the 808 engaged it hit full tight mayhemic low chugs but the moment I opened up to a chord beyond a perfect 5th it didn't lose definition and the notes translated well through the compression and gain
I'm seriously tempted to go and get a 6 string version to throw into another basswood body guitar I own to see if the result will be similar.
Sorry for the long winded rant, I'm just stoked at this pickup.
Here's some pictures of it in all its mangled glory.
Never lose with a PAF I love them
