Using this on and off for like... 15 years? I have always had one of these in one guitar or another.. lol. I like this pickup overall. It is pretty balanced.. pretty hot.... but backs off nicely. Not scorching like a Gibson 500T for example, but still has enough gas in the tank to rock.. without the spikey trebles. Things I like least about it..hmmm. Well, it could have a bit more character.. I would not call it a bland pickup per se, nor would I call it a blank canvas. The overall characteristic would be the fact that it is balanced.. probably a good choice for a studio guitarist.. an inoffensive tone that can do heavy or clean. Ultimately, the benefit of this is versatility.
I've had this in basswood, alder, mahogany, alder with maple tops, mahogany with maple tops, etc, etc. guitars. It has a different character with all of them, but you always know it is a JB. There is always speculation, and reference that this is a "Jeff Beck" signature pickup... it has never been. Not sure, but there was some controversy regarding this as to Seymour trying to pass it off as a a signature model.. not sure how the legend goes. LOL! It actually stands for "Jazz Bridge". Hence, the fact that it is very balanced... good for fusion.

As I mentioned.. I have always had this in one or more of my guitars for over a decade. I would say I am fairly sold on this pickup. I think this is a good value given the prices for Gibson pickups for example... which are no better than this. I would make the same choice.... owning this pickup does not stop me from owning other pickups... if I could only own ONE pickup, I might reconsider .. then again.. I might not! It covers a lot of bases.. it could be considered an all-in-one solution.

Had this puppy installed in a Telecaster for about 3 years now. I am a bit of a Metalhead, so.. this does not always get a a lot of play.. but it is certainly a classic guitar and brought to higher levels of versatility with this modification. The Powerbridge gives a decent approximation of an acoustic... in a pinch. The piezo sound is a great option if you need to pull off Stairway To Heaven live... but it also lends itself to great chicken' pickin' tones.And sweet quasi single coil tones for Blues.. Actually.. better on the latter. Believe it or not.. I have tried other setups.. as I need the versatility. I also own a Yamaha RGX820Z.. with Seymour Duncan JB bridge and 59' in the neck.. This is also equipped with an active, battery munching piezo circuit in the tremolo system. Also very sweet.. I would say this has a bit more control over the tone shaping aspects than the Fishman, but this is also a proprietary Yamaha product.. the Fishman is a great alternative to something you can install into your Tele. ( I think they also have a trem version of this for Strats. I have also tried the Parker Fly stuff.. they are all kind of the same result. The signature piezo sound... somewhere between an acoustic and an electric single coil clean tone.

I find this to be a good value... *IF* you need this specific type of versatility from your equipment. Certainly better than an acoustic modeler pedal or even that found in the Boss GT8.. now, if you go Full Monty and get a VG88 or some other high end guitar synth, you can get more realistic, true acoustic tones. It really depends. If you hate those, love your tube amp and like the organic interplay between your Tele and your amp... Get this. If you would use everything in a Roland VG88, for instance... then the Fishman may not be the way to go.. and just pony up on the outboard gear. I would buy this again.. perhaps. I am not a huge Telecaster fan.. and would possibly opt for the Tremolo version for my Stratocasters. It is a great tool to have in your belt if you love your amp and don't want visual modifications done to your guitar.(i.e. Roland GK pickup,etc).. and still bridging acoustic and electric tones for live sets. This is probably not what you would ever consider using in the studio as an acoustic unless you were looking for a very specific piezo tone... It could happen..

Used this pickup in an Ibanez RG550 for over a year... Basswood has a very balanced smooth tone, so.. I think it was a forgiving canvas for a pickup to make an impression. I have had extensive experience in tone dissatisfaction.. so I am always changing stuff in and out of guitars.. It IS a disease! I have used Fender, Gibson, Paul Reed Smith, EMG, Dimarzio, Seymour Duncan, Carvin, etc, etc.
Alright. So, now the pickup. EMG81. The pre-eminent metal pickup of choice for all the Nu-Metal kiddies. This pickup has been around FOREVER. I think I was using this 12 years ago.. maybe longer... so this is definitely not the new piece of gear lots of people think it is. Very high output, neutrally voiced pickup. It has a lot of clear, boosted signal. Kind of the opposite gain approach of the Dimarzio HS-3.. which is a low output... very, VERY neutral pickup. Zakk Wylde seems to love this in a Les Paul.. I imagine it might be a good choice in that guitar.. as the maple may add brightness.Let me also add that he has a maple neck, so.. this has a small bit of impact as well. In the Ibanez, it was opaque. Flat. Neutral. Can't think of any other boring adjectives to describe it. The good news is.. it should take on the characteristics of your rig. If you have a good preamp... or a Marshall JCM800.. with a bunch of Boss pedals in front of it.. you might be able to get a nice dark, heavy tone. (like Zakk) Not particularly complex.. pretty straightforward, high gain. Easy pinched harmonics, but not rich and detailed sounding. The best way to get a rich sound would be if you have a crunchy amp.. and use this to push it into higher gain. I'm sure Zakk Wylde's rig would not scream quite so loudly if you played a Strat thru it. The best part about this is that it is verbose. Huge. Fat. Like playing a regular humbucker with a clean boost. (One good way to avoid buying this, changing your pots and adding batteries) But if you want a dead quiet, high output solution.. need your notes thick and meaty (and your rig provides the character you want) this is the way to go. You hear it on lots of heavy albums nowadays... the question one has to pose themselves is... Do I want to create my OWN sound? This might be it... but there are lots of other options.

Using this pickup for 2 years now. I dislike this for cleans.. as it is quite sterile and lacking in personality. It is not bad, per se... it can certainly be clean, but has no quack or other desirable single coil characteristics in clean or distorted mode for that matter.. this pickup seemed to be designed for one thing... to have gain heaped upon it and not get muddy.. even with the signal loaded, trebles up basses up. this can handle extreme amounts of gain. Retains clarity.. and begins to sing as you increase your gain. Very odd philosophy behind this. You totally use your amps gain.. this is very low output. The opposite idea behind say, an EMG 81. The signal hitting the amp is weak.. but this lets you dime your rig without your sound turning to mush. You would need to lower your gain on your amp if using hot pickups as opposed to being able to crank it. I have used lots of pickups.. this has changed my overall approach to my sound. I like using other devices to achieve my gain now.. and use pickups like this and the EJ Custom. Add all the distortion I want and no slop. Just a detailed warm sound with lots of heat. I can get metal sounds... but with character. Becomes more fluid/flutey as you add more gain.
I think this is an insane value for the price. If you can't get a great heavy sound out of this.. get rid of your amp. Or maybe get a guitar that is not made of concrete. Get a wooden one.
I will always have a guitar with this pickup in it. I give it a "9" because I need it for my tone. It allows me to achieve heavy heavy sounds.. but not at the expense of detail.

- as for the others EMG pickups, the SA improve clarity, définition and sustain while providing warmth (alnico magnet)
- a great single coil for cleans and low distorsions.

- Had three of them since 2000
- as for the other EMG pickups, this one brings définition, high output, and improved sustain. You can do almost everything with the 85 (much more than with the 81): bass are really huge and the alnico magnet provide warmth
- i had tried lots of pickups (passive and active) and this humbucker has been my favorite for years

- I had two of them in 2000 and in 2007. I didn't keep the first in 2000 because i find the sound thin and trebly. In 2007 i decided to give it a second chance in case i got a faulty one the first time: the sound was still synthétic to my ears (even on a tube amp). I also had EMG 60, 85, SA and only dislike the 81 and the 60 (those two have céramic magnet).
- as the others EMG, the 81 has great clarity, définition and gain, they are great for métal, and i think they would be perfect with Mésa tube amps (to bring more clarity and articulation to the distorsions)
- a very good pickup, but i prefer by far the 85

I've been using this pickup for a few weeks now. I installed it into a Switch Wild One guitar, which is a solid body guitar made out of "Vibracell" material (plastic) with a single humbucking pickup in the bridge. I had planned on changing the pickup before I even got the guitar because I'm a pretty big fan of Seymour Duncan pickups, but the Switch pickup sounded pretty good, better than I was expecting, so I waited a while to change it out which turned out to be a good thing, as I had gotten used to the sound of the old pickup.

The first thing I noticed is that the output of this pickup is much higher. That is to be expected, as the Invader is designed to be a high output passive pickup. Despite the higher output, it sounds as if the noise that this pickup makes is actually lower. Perhaps the noise is masked somewhat by the higher output, but I've listened closely to the pickup without playing it, and I can't hear anything.

I wired the pickup to the coil tap switch just like the old one, and what I've noticed is that, when playing the guitar clean, the output drop from humbucker to single-coil is more than it was with the old pickup. This makes sense to me though; if there are two coils and both have hotter outputs, then obviously dropping one out will make a bigger difference because you're losing more output. Anyway, I say this is noticeable when playing clean because when you throw a couple effects into the mix, it becomes a moot point.

One of the great things about this pickup is that it seems to be more flexible because of the higher output. Some of my effects change their character quite a bit when I use the volume knob on the guitar, and when I tried the new pickup, it immediately threw the pedals into overdrive, almost a bit too much. The range of the volume knob has basically been extended.

Some hot humbuckers seem to get a bit dirty at full volume, even when played clean, but this pickup sounds clean to me. Cleaner than the Hot Rails for Strat that I have in my other guitar (which isn't very dirty at all). Even when playing hard, it's just not dirty, just nice and loud. Traits like this are what always impressed me and made me come back to Duncan pickups again and again.

This pickup at full volume thrashes the Little Big Muff and tears my Synth Mangler a new one. Sometimes I have to dial it down a bit for the Synth Mangler, but it's always been useful to adjust the volume knob with the Mangler; now it is even more so. And yet the pickup is good for just about anything. It's got a great, full clean sound.

I've heard some people say that once you put an Invader into your guitar, you won't want to play another guitar without one. I can see why they say that. It's a fantastic pickup. For me personally though, I'm not going to be replacing every pickup in every guitar with an Invader, because that's just not my style. If I didn't like trying new pickups, this would be a good one to stick with though. I'm pretty sure I like it a little more than the Hot Rails, which I already loved. Duncan is simply the brand I go to when I look for pickups, and this is another example why.

The pickup was a bit of a surprise to me, for the reason that I wasn't exactly sure what to expect. You can read about the pickup and Duncan's recommendations for applications of it on their website, but from reading that, I was almost expecting this hot humbucker to be dirty. I'd say it's as clean as a humbucker gets, which is a great thing. It's simply LOUD. I think the only hotter pickup you could get from Duncan would be an active.

I can't say enough about how much I like this pickup. It's just great. It almost seems a shame that Seymour Duncan recommends it for heavier styles of music, because I feel it could be suitable for just about anything with a simple tweak of the volume knob.

Oh, I almost forgot: the single-coil sound is great! It sounds pretty much exactly like a nice Strat on the bridge, very bright and yet full. Crystal clear sound. The old pickup was good but didn't sound too great as a single-coil. But this pickup sounds fantastic!

I can't ask for anything more from such a reasonable priced pickup. No real flaws at all.
