Dimarzio Tone Zone: I got it in a baswood Ibanez RG and I am pretty happy with it. In E standard it's really nice and controllable for rhythm, it's not the mud monster I thought it would be. It's chock full of mids which might make it sound congested and weird with the wrong settings, but it's actually pretty tight in the bass department. You can safely scoop out some mids and it will not sound bad, because the mids are there in spades. It has a bit of an AWWW sound to it too. Single notes stand out with great articulation and are really smooth and cutting at the same time. I really like it.
Dimarzio D-Sonic 7: Again it's in a baswood Ibanez (RG7621) paired with a Liquifire 7. I take alternating turns in liking and hating these pickups. In the Ibanez the D-Sonic sounds a bit like a JB with some more "normal mids" (presuming the JB has scooped mids and boosted high-mids). I have set it with the bar towards the bridge. It's not really tight, it's not really high output, it's not really compressed. It's a bit of a "middle of the road" pickup. It's got good clarity and good mids, but it's not outstanding in any way. Same about the Liquifire - not bad, but a little conservative, a little too round and muddy. EMG 85 in the neck (of an alder guitar) beats it in any department including tonal balance, picking sensitivity and dynamics (IMHO!).
I have a Blaze Bridge laying around, which I plan on testing instead of the D-Sonic. Ola has made some great sounds with it in an Ibanez RG1527, so I have some hopes that I will like it.
My new project:
A few days ago I got a Yamaha baritone guitar (RGX420S D6). Alder body with maple/rosewood neck and 26 1/4 scale length (1667mm ).
Got it without pickups, only the pots are left in, so I would rather just install some passives to save me the hassle. Unplugged it resonates beautifully, moreso than some of my other twice more expensive guitars. Will be tuning it to B standard with some thicker strings; I got it tuned to E with some 8-38 size strings and man it plays effortlessly.
Following a very lengthy research, I think I will put a Dimarzio Super3 in the bridge and an Evolution Neck.
