"This is partly my fault (due to inexperience) but the description really isn't clear either -- the bridge pickup is the standard-spaced version. This refers to the string spacing, not the fit into the body of the guitar. So this set is wrong for many guitars such as newer Epiphones or any other guitars that have an F-spaced bridge or tremolo. I have a new Epiphone LP Standard and the problem is that (I only realized after installing) that the bridge pickups do not line up with the strings and the high E string is almost completely outside. The goal with pickups is to have them line up with each string -- otherwise it looks very bad, and arguably performs worse.If you don't believe me, you can see the recommendation from pickup-maker DiMarzio who says "many guitars with fixed bridges (including post-1998 Gibson® and Epiphone® Les Paul®, SG® and semi-hollow guitars) should have F-spaced pickups in the bridge position. Most tremolo equipped guitars that have a nut width of 1-11/16” (43mm) or more should also use an F-spaced pickup in the neck position."Probably more experienced guitar folk already knew this issue, but there is nothing in the description of this set that makes this clear. It does mention "standard sized" but that is in reference to being a "drop in" (which I assumed meant it fits in the standard-sized slot).Normally I would blame myself for being uneducated, but there wasn't anything in the listing that even prompted the question "is it the right spacing".Plus Seymour Duncan wouldn't suffer by advising the buyer properly since they do sell the right one. So I have to buy another one for $99 bucks so am giving 3 stars.But the main thing is I want to help others avoid this -- please check the spacing of your strings at the bridge! If they are F-spaced (and most new Gibson and Epiphone LPs probably are) then don't buy this set. Instead buy them separately. The standard P-Rails which you should get for the neck are "SHPR" and the F-spaced ones which you get for the bridge are "TBPR" series."

Put a set of these in my Les Paul with a set of the triple shot mounting rings. It all actually works, 4 different sounds right out of the box. Highly recommend.pioneer meds llc

I installed these as the third set of pickups on my custom built Smith Riviera. The guitar finally came alive. I now use this guitar on rock gigs, funk gigs, country gigs and (most challenging) jazz gigs. Not every variation is true to the original, but when you stop attempting to compare them to something else and accept them as a unique animal you will love them. Best used with the Triple Shot rings and an expander push/pull the latter of which allows me access to neck/bridge and all three PU options.pen name

Set up: replacing two Humbuckers in a T-style guitar (3-way switch, 1 vol, 1 tone, DPDT mini toggle).Guitar previously had two HOT Schecter apocalypse Humbuckers with a garbage coil-split yielding 6 voices, 3 of which were actually usable. Now I have 9 voices ( Humbucker x3, single rail x3, and p90 x3). ALL the tones are viable. Most impressed with p90 tones and Humbucker tones—single rail tones are very good, but not vintage. While the apocalypse Humbuckers had very solid balanced tone, the new P-rails are awesome all around. Do your homework—make sure they work and have wiring diagrams for your guitar before you purchase. Now my guitar sounds incredible.What Customers Talk About
