Yeah, I'll pull the cover and check, but I'm fairly certain that the trim pot is cranked. Maybe that's all there is to it, and using the same strings. I really like the Pure Blues. A lot of people complain that they're lifeless, but I like my strings to have "matured" a bit. Hell, The TI flats on my P-Bass are 7 or 8 years old and I love them. The Pure Blues have a round core and feel nice and somewhat bendy. The Kubicki Nickels seem a bit stiffer but I like them OK. Plus I like giving Carla and Mike my business when I can.
