Not trying to make it sound like a Les Paul, but considering the possibility of picking up another RG920 next year, and was wondering how a more vintage sounding pickup would sound in these guitars. I had them in a Les Paul once and thought they sounded killer.
They will be just fine in a superstrat in 2014. Hear me out:
While it's a proven theory that the trusty EMG 81, Duncan Distortion, Duncan JB, and DiMarzio Super Distortion are a good hot pickup for heavy metal in the typical heavy metal superstrat, you can also get heavy sounds from weaker pickups, too.
Other than loading up on the magnet and winds to get more output, you can actually increase sustain with less output and fewer winds and coupled with a powerful amp, you can also get a similar monstrous sound. The overall effect will be the same whether you have a powerful ceramic magnet to get a hot sound or get there by turning up an amp with a weaker pickup with less magnetic pull. Side by side most hard rock classics will sound the same if you put it through a Marshall half stack cranked up.
The Duncan alnico pro II has the added benefit of being equally at home in a full hollowbody as the cleans are better than a Duncan Distortion or DiMarzio Super Distortion.
I say go for it unless you have a 20 watt practice amp like me. I also play Marshall stacks (and have access to drummer's 30 guitars ranging from vintage pickups to EMG 81s) so I use the amp to metal anything up as long as it's not a full hollowbody subject to feedback. With big amp, it's just a matter of changing volume settings but you can rock out with a Floyded superstrat and Slash pickups. Trust me, you won't know the difference. Don't listen to any ridiculousness that the Alnicos can't handle modern metal or the high octane Floyds and divebombs. It's a pickup in a solidbody and six strings are being ported into an amp with a speaker and as long as you have enough wattage, the Slash pickups will get you there.
If you don't have enough umph with Slash on Floyds, get the Tube Screamer!
