I am interested in buying a Gibson LP Special 100 Double Cut 2015. This guitar has P90 SR and ST pickups the specs are at http://www.gibson.com/Products/Electric-Guitars/2015/USA/Les-Paul-Special-Double-Cutaway.aspx just scroll down to see the spec of pickups.
I researched P90s on the internet and YouTube and came across Doug and Pats review at https://www.youtube.com/watch?v=q3_U_gRCuL8
They reviewed Gibson LP P90 stock pickups, Lollar, Tyson Tone labs, RC and Sandford Magnetics. The latter three are all boutique P90s. I am looking for a great blues sound based on P90s as I have other pickup combos covered. I did not consider Lollar as I did not like the sound from several YouTube viewings and SoundCloud listenings.
I came across Tyson Tone Labs on the Gibson LP thread and also in Doug and Pats review. They do 57s, 53s, 50s P90s so very vintage style pickups. Their customer service is also very good and helpful. I also contacted RC who recommended Plus in the bridge and Standard in the neck, emailed back within a couple of hours. Nate Sanford was extremely helpful recommending 9077 P90s and emailed back in less than an hour from Canada. The examples on the Doug and Pat show were 9022. All ship to Thailand with USPS.
There are other p90s by Dimarzio, Seymour Duncan, but they usually go via dealers.
The 3 shops here also do custom P90s as well as hum buckers so worth a look for the future.
