I bought this kit as a challenge for myself as well as to enter Thomann's diy kit challenge. My plan was to shape the headstock, paint the body and neck. Using no power tools.
I can say that the kit has close to decent quality - with a lot of room to improve. With the provided mechanics, it is a neck diver for sure. Body was 4-piece and neck's single piece. Lots of small holes and dents on the body due to the selected wood. (I wish I could upload photos here) Sealer wasn't applied well. Sanding wasn't even either. So I sanded the whole body to P320 grid. Before starting the paint job with nitrocellulose spray cans.
Neck sealer was a lot better comparing to the body. I am still not sure if the fingerboard is an actual wood or a composite material. But it is dense, dark and has a nice silky feeling to it. Like Ebony... With TV Yellow, it made a nice contrast. It is like an F-brand bass painted in G-style. haha Frets were surprisingly well installed! Kudos! Almost no sharp edges (no more than a short filing/sanding can get rid of). I only needed to polish them to improve playing and look.
Tuning machines are decent, but very heavy. My long term plan is to drill 3-6mm holes to the pegs to provide some weight relief to fight with the neck diving.
No soldering is a plus for peeps are not used to that. No noise or other electro-mechanical issue with the electronics.
Bridge is decent but lightweight. I will change it with a Fender HighMass bridge as I did with my Squier J-Bass.
In short, It was very easy to build, instructions weren't needed. For anyone who is confident with their hand skills and arm muscles, can do the job and enjoy the process, in my honest opinion. (Though, I am an electrical engineer with decent hand skills and my own guitar tech for over 10 years. ) At this price point - though it could be a lot better), It would be great start if you want to understand basics of guitar/bass mechanics, start building your own instrument or just want to make a gift for yourself or a friend/kid.
