Yes, it's the strings for fretless topic again. I've done a search but found very little on these specific strings. I have Dean Markley Fretmaster on my fretless Jazz at the moment. These are roundwounds that are polished over the fingerboard section for better feel and reduced wear. From this you'll know that I prefer rounds to flats (I use steel rounds on my fretted basses). The DMs are great, but very hard to get in the UK and expensive to ship from the US. So I've bought a set of Rotosound Solo (pressurewound?) to try - going to put them on next change. Anybody like to say whether I'll love them or hate them? Generally I've had good vibes with Rotosound Swing Bass for years, but this is the first time I've tried the Solo Bass.
