Re: Want new pickups for LP
Hey there Dre/Dru. Welcome!
You sound a lot like me playing-wise. One question: is this an ALL Mahogany body? I'd think it had a Maple cap also. May not matter though... IMO the Ebony board really does not add so much brightness as it adds snap and fast attack. On with the suggestions:
First - Any of the Duncan classic PAF's will match with the higher output bridge pups. So, if you dig the A2P I say keep it. I currently have , in assorted Les PAuls: a T-Top (That sounds a lot like an A2P), A DiMarzio 59, And a Pearly Gates. The Pearly Gates is my favorite LP neck pup period. That said, I hear you about the neck. I tend to play different styles on different pups in the same guitar.
As for the bridge, a way to look at it is like this:
With the Mesa Amp, I don't think you are going to NEED a high output pickup. That said, they have a certain EQ/Feel/Tone about them.
Based on everything you said, I think the Custom is a great choice. It's kind of like a 59 on Steroids. The Ceramic magnet in there will give you the tightness you want. The highs *might* be a touch harsh, but I have never had a problem with them, and there is a tone knob - use it! Over all when the volume is dialed down I think the Custom can get very mellow. It has good mids. It has more bass and highs.
The other option you listed, a Distortion, is extremely tight in the bass, but has less bass than the Custom, and has much more pushed mids and screaming highs. I'm not so sure you'll like that. It is indeed a 'Metal" pickup whereas the Custom is a much better all-around pup. But - if this IS an all Mahogany guitar, and is pretty dark/bass heavy as is, the distortion may actually be your best bet. It will really dial down the bass and tighten it up, while providing the mids and highs - although going clean is not it's best thing. And you may find the highs a bit much with 500k pots. I like the 300k's with the ceramic screamer bridge pups myself. If tight metal on the bridge is your thing though, this is it. An A2P/DD set would be a pretty wide range guitar.
The JB and other choices don't seem like they will meet your needs. JB can be hit/miss, although if you are playing out in a band, it has it's virtues.
I will point out, that a plain old 59 might really do what you want if you don't need a hot bridge pickup. It may have sufficiently tight bass, and better highs/cleans than the Custom. I still like the Custom as a Metal/Hard Rock guy as it can "Thump and Scream" vs the 59 which has "Bass and Highs"
I also suggest consider the Duncan exchange policy if the Custom isn't working for you.
