I have always wanted to try out the Pyramid flats and since I have a new Fireglo Ric 4003s on it's way to me I figured this was as good a time as any. Looking to get my McCartney circa 1966 tone happening. I know he used them on the Hofner.... only can assume he used them on the Ric too. But knowing his proclivity for cheapness, they might have been the stock Ric strings for a considerable time. Anyhoo just curious as to recommendations for what kind of basses you all have used Pyramid flats on.
