Anything goes in terms of hardware. This is my third one! I have a Music Man, a Jazz Bass-type and now a fretless Jazz Bass, but I'm also thinking of a 5-strings bass. The choice of woods and finishes is huge and the manufacturing quality incredible. Personally, I prefer slim-taper Geddy Lee-jazz bass-type necks, but you can find anything in terms of width and thickness. The choice of woods and finishes for the body is also huge. I have from lacquered birdseye maple to natural rosewood and classic maple for the fretless, rosewood nitrocellulose-lacquered fretboard, with Schaller tuners and Gotho bridges an all of them. The pickups on the fretted are EMG but I went with passive Bartolinis for the fretless.
The necks are very reliable and with an extremely nice finish (according to my luthiere!). As for design, browse the different Fenders and Gibsons available, according to your taste The weight depends on the wood chosen for the body and neck. Don't expect it to be light if you choose a walnut body, and you could also end up with a guitar that "nosedives" if you choose a korina or swamp ash body.
If you know what you want, you can find exactly what you are looking for. The woods are perfectly described according to their resonances and you only need to equip it with some good pickups to get a fantastic sound.
I discovered Warmoth 4 years ago and I'm a big fan! After having had all sorts of basses from many brands, I can tell you that you can make yourself a perfect instrument for half or one third the price of a high-end instrument, like a Fender Custom Shop, Sandberg and similar. Keep in mind that once you have mounted the body and neck, a visit to your local guitar maker is mandatory, unless you are an expert. Personally, I forked out about 900 euros for everything, roughly the price of a Mexican Fender.
