DIY Electric Guitar and Bass Double Neck Kit - 6 String Guitar & 4 String Bass with Basswood Body, Hard Maple Neck & Chrome Hardware - Right Handed - Build Your Own Custom Instrument for Live Performances, Studio Recording & Music Practice

It’s a really good kit, but you have to be patient and pay attention to detail when finishing it and putting it together, or it will not go well. I consider myself beginner to intermediate skill level at various aspects of the project, and while I was successful in the end, it was definitely a challenge. The guitar setups was the hardest part for me, and what I had the least amount of experience with. I found a lot of online resources with advice on how to finish, assemble and setup the guitar(s), and it was a great experience overall that I'd recomemend for anybody who builds or plays guitars.Pros:Full and complete kit – includes all the hardware, nuts, screws, washers - everything you need, other than a few tools, most of which are described in the instructions. I can’t speak to the quality of the pickups, tuning pegs, etc., but after getting it all put together and playing it for a while, both bass and 6-string sound and play just fine, and both necks stay in tune.Precise engineering - all the body and neck cutouts and holes are cut exactly to size, placed exactly right, and everything fits correctly. This is a huge plus and made the assembly process a lot easier.Fully adjustable bridges - height and intonation are all adjustable, per string, which was really helpful when doing the setups.Online video of the assembly process - having this was very helpful, as I'm more of a visual learner and didn't have the printed instructions at the time of assembly. It's in fast motion though, so I had to watch it several times and stop the video quite a bit.Unfinished headstock – this could be a pro or a con. The headstock is blocky and looks unfinished, but that leaves it up to you to change it to whatever you want. But if you don’t do something, it’s not a great look. I considered a few design options, but ended up just rounding the corners to keep it simple.Cons:All the frets on both necks had sharp ends - this is mentioned in the instructions as a possibility, but was still a time consuming pain to deal with (24 frets on both sides of 2 necks – that’s 96 fret edges!). I went slow and was careful, and still managed to ding up a couple frets. Took about 1/2 a day to complete.Crowded wiring – in the bass pickup cavity closest to the switch, there are 3 wires going in and out, which is really crowded. The first time I screwed in the pickup, I hit and shredded 2 of the 3 wires. I ultimately carved out some extra space by the hole leading back to the bass switch, so the wires wouldn’t contact the pickup screw in the same area, and then was able to reassemble it successfully without munching the wires.Wiring quick connects – This is a pro and a con. The pro is since everything is wired with quick connects, you don’t have to do any soldering! The con is that a couple quick connects were joined together (switch and jack - probably so you can see how it should go together?). There’s nothing in the instructions on how to get them apart, which you have to do to feed the switch wire and jack into the body from the outside. I figured by pinching from the two sides while pulling both ends, they do pull apart.Heavy – this one makes sense, since it’s basically 2 guitars. I was hoping the basswood body would help keep it light, which it did, but it was the hardware, particularly on the bass side, that brings the whole unit to 11.6 lbs. overall. Probably best for gig use only when necessary...Pots/Nuts – the instructions caution against overtightening the nuts on the body when attaching to the pots, so I left them a little loose, which was not good either. The pots rotated around and one of the wires disconnected, which I had to reattach with solder. So be sure to tighten the nuts at least snugly enough so they don’t move.Lack of specs - Setup steps would have been a lot easier if there were more specs provided in the instructions, like neck radius, pickup type, and string gauge for the provided strings. I was still able to get the setups done successfully through trial and error.
