I spent the afternoon yesterday trying out a few sets of flats on my P (I had a few used sets in my box). I've been using LaBella 760FL for a while as they seem to be the standard recommendation - I didn't like them at first as they were quite bright, stiff and sticky, although they got better with age. Tried the Chromes and they had the same issues as the new LaBellas. Then I put the Pyramid Golds on and they are never coming off! They just sound perfect on this Classic 50s P of mine, and are so smooth to the touch that they, to use an overused Talkbass term, 'play like buttah'. Slides are just so effortless and I have the action nice and low - I can't put it down now, and have only done so long enough to write this, and now I'm off again!
