Thanks for the response.
The sound I'm after, well, it's kind of hard to nail down. I'm a big fan of Petrucci, so that'll give you an idea of where I'm coming from, but I would also play quite a bit of Death Metal as well, and then some jazz stuff, kinda like Dave Fuzinski, so I guess I like a versatile sound, but as it's a 7 string, I'd like a tight, clear sound, with good midrange and some bite. If it helps, my favourite pickups so far, are the DiMarzio Evolution in bridge, Lundgren M7 in bridge, and in neck the DiMarzio Air Norton. I've found those work very well for me so far, but everything I've heard about Bareknuckles have been positive to the extreme, so I'm really looking forward to getting some myself.
The thing about getting the guitar first, and then deciding on pickups, is this; the guy I'm getting the guitar from does Bareknuckles, so what I'm planning on doing is getting him to order the pups, and installing it all, so it comes to me all nice and ready to rock, and it's far less hassle for me.
Now, I've been recommend a set of ceramic Warpigs, or the ceramic Warpig/Cold Sweat, and from what I've been told, these are certainly sounding like good choices.
Oh yes, I'll be going for an Emerald burst finish on the JP. ;)
