This is a very good kit to work with and with a bit of effort, will result in a very usable bass guitar.
I've built HB kits before so I knew what to expect. True to form, it was well packaged, delivered very efficiently, and everything was there. The components were all wrapped carefully and everything was complete. It's a kit so I knew I'd need to do a reasonable amount of work on it. You could just build it as is but you get a better result with some effort.
The body was fairly well finished but there were some rough patches and a couple of marks from the sanding so it was sensible to sand it down to 400. Although it didn't need a primer, I applied one anyway because I was going to give it a gloss acrylic finish. After the initial cleaning up and painting the body I checked the neck. Very straight, frets perfect and there were no rough edges. It would have been fine to use straight out of the box but I shaped the headstock and then prepared and painted the neck too - don't forget to mask the fingerboard :) .
Once painted, I assembled the whole thing in about an hour but there were some little irritations on the way. The plastic plate was not cut accurately to fit the neck and needed a fair bit removing with a Dremel. Not difficult but surely it could have been cut accurately in advance. The screw holes for the plate were positioned accurately though they were drilled a little deep so the screws were loose once inserted. I just dipped the ends in wood filler and they settled in fine. These are very trivial irritations.
The bridge was positioned perfectly and once the strings were on I set it up. The truss rod needed only a quarter turn to set the action though getting the action right at the bridge meant the bridge was lowered virtually to the plate. That tells me that I'd have to put a shim under the neck to recover the adjustability. Something the width of a credit card will do the trick. It's not a deficiency of the kit, simply something we need to recognise and deal with for all bolt-on necks. A note in the construction booklet in future might be useful for others.
The pickups and controls were easy to install and everything works fine, both pickups giving a good signal and the tone control has a reasonable range. The downside is that these are cheap pickups and seem quite noisy. Given that the pickup and control cavities are not screened from EMI and since they are both single coil, noise is inevitable. I decided to disassemble the bass, put a shim under the neck join, and replace the pickups with Fender Jazz Bass pickups (from here) and also to line and earth all the cavities with copper tape which should all but eliminate noise. The strings provided are fine but I'm putting flats on for even less string noise.
First time round it played very well and comfortably and there's a good balance between neck and body. Even with the stock pickups, there's a good range of sounds available and it records well straight into a USB mixer. I'm playing mostly jazz and not gigging with it but even through a standard guitar amp, this gives plenty of rich bass tones. Once it has the Fender pickups in it, it'll sound even better.
As with every kit, you'll have to do some work but with a bit of patience and a modicum of skill, this kit gives you a very nice jazz bass at very low cost. Recommended.
