Also an elixir fan, amazed at the sound they produced on a very basic bare bones cheap fretless.
Not really a fan of many rounds tbh.
Had some thomastik infield flats and they are nice tone wise, I developed a strong dislike to the scratchiness of rounds and this definately cured that. They do take time to adjust to the low tension though, very different to Chromes and other flats I've tried. I think I like the idea of heavier stiffer flats so I can play harder without the string clatter and rattle but it never seems to work out and within days I'm changing them. The difference in volume between Pyramid Gold flats and the TI's was surprising, how much quieter the Golds were. Maybe I just haven't given traditional type flats long enough to get used to them.
Currently gone back to SIT Silencers on my P bass, which are a nice alternative and somewhere between flats and rounds, they came fitted on a bass so I didn't see the packet I think they are pressure wound whatever that means but I like them.
Previously used Status strings, DR Black Beauties, Elites for years, Warwick Red and black Labels, but meh. Have some tapewounds on an acoustic which I much prefered to rounds or the horrible bronze things that are marketed for ABG's but are noisy scratchy terrible (to me) strings. A waste of 40 quid there!
I've got a couple of sets waiting to go on, Elixirs on a 5 and some La Bella low tension flats. Fingers crossed eh.
