La Bella 20-PCM Jazz Flats FWSS

Really like these strings, they're finished to a very high quality and very smooth under the finger. I use them on my Ibanez archtop. They give a lovely clear tone (slightly brighter than I expected). What is a nice touch is that they throw in an extra G string so you get the choice of playing a wound G or an unwound G as per your personal tastes (personally I'm using the wound G).
