Okay, I've been on this forum a couple months now and in that time odds are I've been singing the praises for this pickup.
DiMarzio describes this pup as being glassey and combining the sound of a Strat and the power of a PAF and I'd be inclined to agree. The HFH in the neck position does a very convincing job of producing strat neck tones in Les Pauls but with a somewhat bigger, thicker sound while retaining a clean, bright tone with the highs slightly rolled that I've been able to use for anything between Blues Rock and Jazz. Dirty up the HFH and you have a smooth but still defined lead tone perfect for sustaining two hand tapping and legato work especially with the tone rolled down to taste.
My experience using the HFH with a Mo'Joe and Norton in the bridge has also made me quite fond of the middle configuration's tone which in both cases has been configured to be more in favor of the HFH to produce a very nice tone that I can only liken to guitarists like Jimmy Page (think like the first solo from The Ocean or Black Dog) and Mick Ronson (like the clean electric guitar in Space Oddity) or perhaps early Gin Blossoms because played clean it is chimey but still lush and dirty it is nasty and pronounced.
The pickup also handles effects well as I will attest to in this somewhat okay video footage of my band performing live with most of the playing and all of the guitar soloing being done through the HFH using distortion, chorus, delay and boost as fit.
I plan on posting actual sound clips in a few days once I get a real microphone if not before that.
