I've been thinking about building a fretless bass as a new project but can't decide if I should go P-bass or J-bass. I only want four strings, and I don't slap. I'm just thinking in terms of the original Fender styles. I'm leaning to the J-bass. The fretless J-bass is kind of classic, ya know. But I really like the P-bass punchiness, and think it might work well as an alternative to an upright type of sound. So what do you think of when you think fretless Fenders? P or J?
