I play an SG-Standard with Humbuckers through a Vox AC30.  When I’m at home by myself I love the neck pick-ups, it has rich full tones,  But when I play with my band I have to switch to my bridge pick-ups because the guitar tone doesn’t cut through the rest of the sounds being made. 

I hate to see a part of my guitar not being used, so I was wondering if anyone had any ideas on a different neck pick-up for my guitar.  I think I need more treble and perhaps more mids, but def less bass. 

I’ve been browsing the Seymour Duncan site listening to samples, but so far nothing has jumped out at me.

I dont play lots of leads, pretty much down strokes in the vein of Joan Jet

The jb would be something that might work for you. I know that the jb is usually used in the bridge position but I have a guitar with the jb in the neck and I get some nice tones out of it.

A treble booster might help. Screaming Tree!

I’ve been very happy with Fralin PAF and Unbucker pickups.  I always go for underwound on the neck pickup but thats my taste.  Shop around, I’ve found really low prices on his most popular models.

I use a Burstbucker in the bridge and a p90(!) in the neck. The p90’s got about twice the output and it cuts through to say the least.

I realise this is probablly too late but… have you tried IronGear pickups? they are actually quite good, considering they go for less than £50 online. http://www.irongear.co.uk/irongear_032.htm
