Seeing as that you both expirement with and tend to do a lot of slap, modified slap and tapping, have you ever expiremented with flatwounds for such puposes? Knowing that flats aren't nearly as bright (well most anyway) as rounds I was just curious. There seems to be a big 'renisance' as it were for flatwounds. I myself have switched and started using them with my Zon bass. To my knowledge using an upper line active bass and flatwounds isn't really heard of, although I am sure someone else is doing it too. I just love the sounds. I use the D'addario Chromes (and when I play rounds I only use D'addario too) and I have tapped and slapped with them and very much like it. I was really suprised at how un-muddy they were when I was doing all of this. Anyway, have you guys expiremented with flats? What did you like or dislike about them and why? What brands?
