My GB's.
I had a 1980 Ibanez Musician fretless that I loved playing but it just got too heavy for my poor old back so I paid a visit to Bernie Goodfellow GB Guitars who is quite local and said I wanted a four string fretless Spitfire with a neck exactly the same as the Ibanez. Game on. I dont dig basses that want to be furniture so fancy woods were out, although Bernie could not resist using a fancy bit of maple for the neck. Thought long and hard about the colour but in the end decided it had to be black with chrome, standard Spitfire build (GB Pups, GB Active, Schaller 200 Bridge and Hipshot Ultralights). Its made from swamp ash so is nice and light. I did consider a Status Retro in black but I wanted an in-between neck and Status only did P or J.
One extra was some rather fetching blue LED's as playing fretless on a blacked out stage can be a bitch.
Like most builders Bernie has a formula and models that he likes to use as a starting point (the Rumour shape is inspired by the silhouette of a naked woman with a comfortable bottom sitting down). Of course you can vary considerably from the standard build but it can cost more and if it is particularly time consuming he might decide not to take it on because it means making all the other customers wait longer for their babies. But I wanted something different with frets so I had a Spitfire based P bass made. Swamp Ash again in fiesta red with a snot green plate. 69 P Pup, EBS Active, Hipshot Ultra and Hipshot Model A strung through. Looks and sounds very different.
