It's just simple evolution, not revolution. No big steps, just little tweaks here and there. That's what most of the boutique gear is.
And I like it :D
This sums it up pretty nicely for me with the majority of "clone" type gear.
However, most of my gear isn't really all that derivative, in my opinion. I have an engl preamp that I can only describe as sounding like an engl. They have a very distinctive tone of their own imo, one that's not quite like any other amp, at least in the kind of ballpark tones found in the genre of extreme metal that I play. I have a Laney Tony Iommi head, which, in my opinion once again, sounds like a Laney. A lot of people say they sound Marshally, but in my experience the only similarity has been the EL34 influence.
Bare Knuckle pickups, basically PAF clones.
This I somewhat disagree with on a couple of levels. Firstly, if they were attempts at being de facto paf clones, they wouldn't be scatterwound with the skill attention Tim and co. provide. They'd either be wound until the bobbins were full (lol) and fitted with a random alnico mag, or wound machinewound on a leesona for extra "authenticity".
I think it's a case of producing the best sounding pickup, rather than the most authentic (which is a wild goose chase beyond a certain point, as PAF's were a complete cr@pshoot as to what you got). I think it's absolutely the correct approach to take, a pickup should sound good first and foremost. The authenticity of the baseplates, wooden spacers etc. etc. is just the icing on the cake. I think it's pretty bold, maybe even innovative of BK to fly against the trends common amongst the boutique crew and traditionalists and say screw the leesonas or equivalent, they sound better the way we make them even if it's not (allegedly) vintage correct.
Secondly, none of the bkp's I own are even remotely paf-ish, the reason I'm such a BKP devotee is that for many years I thought I was an active guy. I was convinced I didn't like passive pickups, I couldn't get the clarity, aggression or attack I wanted from them. Then I played a guitar with a Miracleman in it and had a tonal epiphany. What I'm trying to convey is, I think the BKP's that I've played are in a league of their own, I don't think any other pickup company makes high output passive pickups that sound quite like the ones Bareknuckle does.
I use what sounds good personally. I try hard not to be swayed by the latest trends and herd mentality. I don't care if something is derivative as long as it sounds the absolute best for the application I'm using it for. Likewise, gear does not have to be innovative or original for me to use it.
p.s., On reflection, music is so evocative of youth and conjures up a lot of nostalgia. I don't think it's a huge coincidence that older generations are so obsessed with era correct gear harking back to the time of their youth is so common (and such a huge market). Give it another 30 years and people will be going crazy for a vintage C-Pig played through their axe-fx clone, so they can bust out some vintage djent (I really hate that word).
