I tried playing a bass with flats on it at the guitar shop the other day and I'm considering getting a set but can't decide which bass I want to put it on. After selling my Squier CV 60s P today, I'm left with my TRBX304, a Fender J, The ESP LTD fretless I'm getting in 2 weeks, or the PJ kit/parts I'm building. Any suggestions? Someone suggested to me to put flats on the fretless but... It will most likely be my main player and I don't know if flats will give the punch for some of the varieties of music I want to learn. Not to mention strings aren't cheap. TIA for help
