which PUP for my archtop

[Ochaye]

which BK would be best suited for a GIBSON es 137 do you think?

guitar to be used for 90% R  n  R and 10% jazz

[ericsabbath]

mules

[Ochaye]

Hmmm got 'em on me les paul

[kevinr]

AII Stormy Mondays or MQs!

[PhilKing]

Another to look at would be Manhattans.  They are a lover output P-90 in a humbucker size cover and are very like the old Gibson jazz pickups

AII Stormy Mondays or MQs!

+1

[Fourth Feline]

From my ownership of Mules, Manhatans, S.Ms and M.Qs , ( and for your balance of usage ) M.Qs would get my vote.  

M.Qs will give you a tighter / punchier bass end and assertive yet smooth high end detail for double stops / 50's Rn'R riffs. ( on the M.Qs , Pickup height adjustments can modify the top end between glassyand fat, to sweet yet biting ).

The AII Stormy Mondays are lovely pickups, if you had stipulated  80% Jazz / 20% R'n'R .

Manhattans are ( for me ) 100% Jazz .

Mules would also be favourites, but there is something about that M.Q sound - that breathes life / a unique tone into a semi-acoustic.  :)

The last point to consider is that M.Qs are a low noise / hum ( i.e. encased in a nickel 'cage' ) single coil, and the Mules hum proof.  Whilst I have never heard single coil noise on my own M.Qs, I feel it only proper to at least mention that it is theoretically more probable than with Mules.   :)

Riff Raffs could also be an option. Don't know if they're good for jazz, don't know how they sound with the tone rolled off a bit.

Riff Raffs would turn that guitar into a Chuck Berry machine.

MQ's gets my vote as well. Have 'em in my Reverend Manta Ray which I think is quite similar to a es137. They really sing in this guitar. I'm no jazzer, but I sure the MQ's can pull of some.
