I have a custom bass that is my main bass and i love it. Its a 4 string. I commented the idea with the builder and he said he should take measurements first... Ok, this is the dilema: Yes: - The bass is a neck through singlecut (fodera style) with a P-bass neck measures. Kinda chunky. I use light strings so it should be fine in terms of neck tension. - Im not a metal bassist but want to be as pro as i can and be able to play low notes when its required (i know a pro bassist would buy a fiver, but i love this bass) - A narrow spacing is not an issue for me if its a normal spacing that you could find in other basses like 6 string basses for example. If its not a weirdo, subnormal spacing, its ok. - The pup im using have blades inside, so no pole-aligment issues... No: - Theres no way i can try the feeling, neck response and string balance and get back if dont like it. - Weird looking headstock with an extra tuner added (its a Warwick's shape headstock) - B is not that necessary to a point you are not able to play or get a gig. - Probably narrow spacing makes slapping more difficult - Have to use rail bridges for each string to adjust spacing (dont like those) thanx!
