Hi, :)
Just to add that the Mississipi Queens are my favourite pickup so far for Blues / Jazz ; especially 'clean' playing. I use mine like a more assertive Stormy Monday, but with much more clarity and articulation in the bass strings. For my purposes, I am getting some sweet Larry Carlton like tones - but can hear where they would bite harder if I dug in. The whole concept of a P90 type pickup was alien to me ( except for dave Gilmour's ace solo in 'Another Brick In The Wall PtII ). As such, my ordering of a matched M.Q set was something of a calculated risk. I am so glad I did take the plunge though, for as much as I love my AIV Stormy Mondays and AIV Mules, the M.Qs have a unique and ( for me ) irreplacable character. As mentioned before, the clear but fat and sweet top end is perfectly balanced by the ultra clear bass end. Unfortunately I do not have recording facilities, but think highly enough of mine to sign in and comment. I've had then in a 1976 S.G. Standard and a semi-acoustic 335 copy. They sound different in each one, but beautiful all the same. The semi obviously imparts more 'air' - but the solid mahogany is a great foundation from which they can project.
happy hunting ! :D
