I held off on this thread because I usually let TO answer the metal questions, however in this case I just thought I should list the pickups and amps that our opinions are based on:
Pickups/guitars
53 Les Paul with Black Dogs
86 Goldtop with Cold Sweat/Pain killer
Custom Les Paul with PAF rewind and Riff Raff
67 335 with Stormy Monday set (AII)
79 Hamer Sunburst with Abraxas set
Zemaitis Clone with Emerald/Mule
Richwood Explorer with Warpig/MQ
PRS Artist with VHII set
PRS Standard with Rebel Yell set
PRS EG4 with Crawler/2xP90
Warmoth PRS clone with Miracle Man set
Super Strat with Holy Diver/2xTrilogy Suite
Ibanez with Nailbomb/Irish Tour/Cold Sweat
Double cut LP Junior with Pig-90
60 LP Standard with BK P-90 Rewind
Custom set neck with MQ/Slowhand/Mini-Mule
57 Strat with Apache Set
custom hollow strat with Irish Tour set
60 Strat with BK rewind and 2 original pickups
57 Tele with Brown Sugar and Slowhand
59 Esquire with Piledriver
Custom Strat with Cold Sweat
Kamakazie with Miracle Man
Strat with VHII/Irish Tour
Wayne with Cold Sweat/Trilogy Suite
Agile LP with Riff Raff/Stormy Monday (AIV)
66 P-Bass with BK P-bass pickup
Then there are lots of original 50's.60's and 70's guitars with the original pickups and also many after market original replacement pickups including SD, DiMarzio, Tom Holmes, Bill Lawrence, EMG, Mighty Mite, Lace and others who disappeared because the pickups were bad (Ultrasonic come to mind!)
Amps
Marshall Silver Jubilee
Fender Blackface Princeton Reverb
Fender Princeton II
Splawn Quickrod
Laney 30 watt
Diezel VH4 & Herbert
Roccaforte custom 80
Matamp Mini Mat, GT1
Several custom made McIntyre amps (Studio 205/Bluesmaker/Prince o'Wails, SP3)
Lexicon Signature 284
Victoria Bassman
Comet (Trainwreck)
Cornford 50 & 100
VHT Pitbull
Carr Slant 6
Also VG88 & Johnson J-Station modelling amps.
I think this might just constitute more than one or two amps and sticking to one sound. It might also explain why we do come up with some ideas on sounds and also the best pickup combinations.
I have tried several of the pickups in different guitars before finding the one that worked best for them.
Tim will definately steer you right if you ask him, but don't think that other people haven't tried a lot of options before they answer.
As I mentioned at the start, I don't normally answer anything on metal because TO knows so much more about it than me (Classic Rock and Blues are more of my forte), but I think that it is good to know that when several of the older regulars make a posting, they are basing their opinion on a wealth of knowledge and not just hearsay.
