I bought these pups to replace the lifeless humbuckers on my Gibson 2012 Les Paul. I installed and wired them up useing Triple Shot mounting rings...everything worked fine and they sounded good through my effects pedals linked to my computer at home. My band had a gig on the same night that I installed them, so I took this Gibson Les Paul with new P-Rails along with my old faithfull Gibson SG to try these new P-Rails out. For the first half of the gig I used my Gibson SG its an old one and always sounds good. The second half of the gig I put on the Les Paul with the new SHPR-1 P-Rail pups. I play in the style of Gary Moore and co..rock n blues. So how did they fair? Well I wasn't disapointed they sounded fantastic, I thought they might be good but not this good, the p-90 and humbucker sounds were great. I can recommend these pickups they certainly put life into my Gibson 2012 Les Paul they realy compare to the old P-90 and Humbucker pickups you won't be dissapointed.. I wasn't.
