X2N7 ReviewPhew... ok I finally managed to slot in some time with my 1527 with a newly-installed DiMarzio X2N7 in the bridge position.
Just a little background concerning why I chose of this p/up:
1. I've been GASsing for an X2N since way way back and was considering installing it into my Jackson RR3- on the spur of the moment however I opted for an EMG81/85 combo instead.
2. EMG81-7 or EMG707 would have required body routing on the guitar... and the p/ups themselves aren't very easy to source here. (DeadEye, no comments please...

)
3. It's the highest output DiMarzio 7-string p/up and it has rails (FTW!).
4. Reviews on sevenstring.org etc say that this p/up is tight, brighter than the 6-string X2N and is dead-on for metal.
So with these things in mind, I plugged in my 1527 into my GT8 and dialled up the standard metal rhythm/lead patches (Mesa R-Fier Mdn 1 sim + 8x12 cab sim) which I made for the Jackson RR3+EMG81/85 combo; basically to get an A/B comparison between the EMG81 and the X2N7.
Shhhh....I had one real fear before getting this p/up though... noise.
The EMGhas an RMS output voltage of 1.25khz and a peak output voltage of 1.75khz. IIRC, the EMG81 is actually a low output passive p/up and it's the active electronix thingy which boosts the output into "Stand Tall and Shake the Heaven" regions... supposedly that's why it's a relatively quiet p/up.
The X2N7 on the other hand is a straight-out ballz2Dwallz high output p/up so I was a bit worried that I'd get some serious feedback issues... surprisingly though, this p/up is quite quiet. The verdict is still out though because I've only tried it at slightly loud bedroom levels (twas be 2 hours till midnight, and t'would be impolite to blast

) ... will have to see how it fares at band playing levels though.
RhythmSince it's a 7-string, naturally the first power chord I hit was the low B and I thought to myself... wow, the distortion is as saturated as the EMG81. I played a few random palm-muted riffs on the B string (8th notes, 16th notes, syncopated, straight... standard power metal fare! "16th notes are the only notes!") and the thing that really struck me was how tight and clear the 7th string sounded. Heck, when I played on the 6th string it sounded even clearer and tighter than the EMG81! It was so bloody addictive that I spent about 15 minutes doing nothing but chugging aimlessly on the 7th string...

I think the difference between the EMG81 in the Jackson and the X2N7 in the 1527 is that the EMG81 has a bit more mids than the X2N7... according to the EQ chart on the DiMarzio website, the X2N7 has a pretty flat EQ curve with a very slight dip in the mid frequencies. Also probably it's because the Jackson is alder whereas the 1527 is basswood... who knows, I'm not very well-versed in guitar woods... hehe...
LeadMy lead patch is essentially the same as my rhythm patch, but I back off the gain on the R-fier sim and slap a T-screamer sim in front as a booster... plus a bit of EQ boost in the 2khz range. The X2N7 responded quite well- it may not be as bright as the EMG81 but it sure as heck sounds more "alive". Interestingly enough, according Tham (who has an X2N installed in his Ibanez Rhandy Rhoads) the X2N7 is a lot brighter than the 6-string X2N... then again, IIRC the X2N7 is not so much a modified X2N for 7-strings but more of a complete redesign. Oh well, I like the results...

For slow lines, the X2N7 has a bit of a sizzle to it which makes it "sing" nicely, but not so over-the-top. Surprisingly though, for fast scalar runs on the lower strings (7th to 4th strings), the notes sound clearer than the EMG81 in the Jackson. (...ok, I know a statement like this generally attracts comments like "if it sounds jumbled up, it's probably your technique wtf!"

... but since I'm comparing
my own playing on the Jackson+EMG81 against the 1527+X2N7, that's as objective as I can get, so there!

...in other words, runs sounded less sloppy on the X2N7 than the EMG81... hehe...)
Yes, in my euphoric state, I even tried sweep arpeggios with this thing... it didn't really sound very clear, but I'm going to refrain from saying any more because that, I can safely say, is probably because of my technique (or lack thereof)...

...ok, the above was all tried with the p/up selector in the bridge position.... when I switched to the next position (2nd position from the bridge... the one where it uses one bridge single coil plus the neck p/up in parallel), ...the sound was single-coilish but still punchy. Gee... the output however was as much as my neck p/up (stock Ibz V7-7) in serial...
Clean tone... huh what?!Hehe... I remember reading on the DiMarzio website...
"If you're looking for pretty sound, don't go here. If you're looking for pretty crazy, this is it." 
That pretty much sums up how the clean tone sounds like...
On a more serious note however, chords don't sound as jangly with the X2N7 as with the EMG81. In fact, if the p/up selector is in the 2nd position from the Bridge, it actually sounds quite nice... punchy, clear and bright yet not piercing.
The EndI can safely say that I am now a DiMarzio convert. If I were to do a one-word against one-word comparison with the EMG, I'd say that the EMG is a "chainsaw" but this baby is a "chainsword" (
"In the grim darkness of the far future, there is only war." ..hehe...) Brutal, yet with more finesse than the EMG81...
Now the only problem is getting a decent neck p/up companion for this beast. I've been eyeing the DA7 neck which has an interesting treble spike... but I may also consider another X2N7 just to get that tight sound for my neck p/up. Plus, quad rails FTW!

So, in conclusion...
This thing is: like cold steel, good for slaying dragons (+1 against chromatic dragonkind), saving the green valleys where unicorns run wild, defending townes against the evil forces of the Abyss... essentially- metal.

This thing is bad for: anything that's not metal. On that note, I'll end with a quote from Joey DiMaio...
