Last night I installed a Duncan Pegasus-7 in the bridge position of my Jackson SL7.
It previously had the stock Duncan Distortion-7, which was a lot of fun to play in isolation but didn't provide usable tones for recording. I prefer it to the six-string Distortion, but it still manages to be both messy and harsh at the same time.
The Pegasus is sort of inline with the Suhr Aldrich as being a "JB without the annoying stuff". None of the low-end wooliness and nasty upper-mid spike of the JB. I've seen the Pegasus criticized as lacking character, but it responds well to pole piece adjustments and you can make it thick like a Timbre Wolf or more precise and cutting like a JBJ (in some guitars).
It lacks a little of the richness of a Timbre Wolf, but the low B responds really well with no muddiness. Perhaps I'll change my mind, but for now the Pegasus seems like a keeper.
I might end up putting a Sentient in the neck, but the Distortion-7 neck position is pretty good for lead tones (which is all I do with the neck position on a Soloist).
