La Bella ASP-45103 Ian Martin Allison 4

Beeing a huge IMA-fan, I bought these strings for allround use on my MIJ Fender Jaguar. They live up to my expectations as great allraound strings; Sounds not too bright, not too dark - like great sounding dead roundwounds. Feels more like a smooth semi-flat. I don't find them harsh or sticky at all. Great for both fingers, pick and slap.

Used a lot of strings. New ones are too bright and stiff. Flats are to dull and sometimes to stiff. This for me is a perfect compromise. Great feel, bright enough. Not too dark for allround playing. Totally love these.

Roundwounds + Flatwounds - the best of both worlds? Far from that. These strings are marketed as having "flatwounds' feel" - they don't. They are harsher to the touch than a 3-old set of normal roundwounds (Addario) I had previously on my P-bass.
They sound good and are LaBellas anyway, but feel to the touch exactly like a set of roundwounds. It is a cheap marketing move with Ian Allison's name on it.
