DiMarzio showcases Jake's signature pickups on [this product page](http://www.dimarzio.com/pickups/humbuckers/high-power/titan-bridge). The DP259s come Standard in Jake's Signature [JMB100](http://equipboard.com/items/ibanez-jbm100) Ibanez guitar and are PAF style type pickups that are geared toward prog metal. The neck pickup is higher than the bridge, being that jake does a lot of single note ambient type things in his band periphery.
I installed a Dmz titan in the bridge of my ibanez rgt (hardtail, dual humbucker, 5 way, 5 pc maple walnut neck, mahog wings), replacing the sh-11 custom custom. It was absolutely horrible for anything tuned below d standard, including drop c even. Wasnt tight enough for chuggy stuff, but i didnt expect that from a medium-low output a2 pickup. Im honestly at a loss as to why it was ever installed in a guitar designed for metal (it also has a 59 bridge in the neck...people do weird shit). This was my first pickup install, and to all the guys who have never soldered before and are scared of installing a pickup on their own, just do it, it's the easiest thing ever.
The low end is tight, but dynamic as hell. Your picking needs to be very consistent, if its not, youll definitely hear it. Its very scooped out and i brought the bass up to 6 as opposed to having it at 4 to compensate and theres no mud, even with the artificial bass boost. The midrange very pronounced. I went from having my mids at 7 to having them at 4. The titan is ridiculously sensitive to height adjustments. Itll go from over the top tight and gainy (super djent) to a bit more relaxed and smooth, but still tight and controlled. I seriously spent about 10 total minutes fucking with the pickup height. . All the strings have equal volume, the titan is incredibly clear with big chords under high gain as well as mid gain and cleans. Compared to other pickups it's somewhere between a dactivator and an illuminator (or between a nazgul and an omega). The titan tends to emphasize all the wrong kinds of mids and it gets super annoying. I havent found a way to get rid of that issue after having it for almost a month. Im returning it for a juggernaut. Hit me up with any questions and i'll reply asap, i know this review is a bit shite.
