Just was pondering the general question in the title, and wanted opinions from all you folks...
A lot (all?) of my bridge humbuckers are high, but not super high, output. I have a Diezel Hagen + Herbert I play through most of the time, so there's plenty of gain available for whatever really. But I tend to play a lot on a single coil neck for some of the more funk and blues stuff for the added clarity, zing and lack of compression. So one of my favourite combos is a Nailbomb (Alnico) bridge and a Mothers milk neck. Gives me all the heavy rock + the funk and blues I require. Think Tool/Clutch/Corrosion of Conformity/Limp Bizkit/Karnivool but with added SRV, RHCP, James Brown and more ambient chillout for want of a better description Or another has a Holy diver bridge + Mule neck. So again, often one pickup for heavy, one for less heavy/clean/rock. With the caveat I often use say the Mother's Milk neck for heavy as a rawer twangier full gain sound, and the bridge for clean or lower gain sounds too, sometimes just using amp channels for less gain, sometimes just with a slightly under full-gain sound and lots of volume knob action. And usually in drop Db, so lower and more meaty but not 7-string territory.
Anyway, to the point: some folks use pretty stock output pickups from Les Pauls or PRSes, and their amp does all the gain with great rich heavy tones and use those pickups for a lot of lovely clean bits. Also quite a lot of heavy players tend not to choose particularly high output pickups for certain low heavy progressive stuff. So my next bridge pickup I was pondering a bit less gain and something like a rebel yell or maybe VHII. I mean Steve Stevens has a great rocking fat lovely tone, and so this could be for me a quieter Nailbomb with more dynamics or clarity and any lack of gain than usual I just dial up on the amp. But then I watched Rabea Massad demoing the Silo pickup, and it equally does a beasting sound and his cleaner tones are fine, and the compression of the higher output pickup may seem to more just add smoothness. His band is closer to what more progressive stuff I'm normally playing than more classic Billy Idol, but I love a vintagy lower gain sound too thats not to 'clinical' and a bit more woody. So this has flipped my head somewhat. So next bridge pickup I go for I'm gonna try and avoid the usual "hot", and either go hotter, or weaker, but I have no idea!
So, pros and cons. Do you play heavy stuff/progressive/mixed stuff and have tried a variety of bridge pickup output levels? What's your take? Obvs I can still have a funky or lower gain neck to switch too if I go balls deep in super hot windings, but equally playing your main heavy sound on the bridge pickup, just rolling off volume into daydreamy chilled blues noodles and swelling back in to full gain seems like maybe it could be optimised better with a lower output bridge bucker? But I have no idea, you tell me... what's your experiences... the more varied opinions the better the discussion too! :)
