But the only shop with them here in Christchurch has had three different ones over the last 12 months or so and every one of them had a misaligned neck. You can see in the photo below that the G string is much closer to the neck edge than the E string. It did affect the playability to me. I had a look at their stock image and it is also the same. My photo.... Stock image....
Very poor quality control. It looks like it's a bolt on neck so there may be a little wiggle room available to pull the neck over a bit but from your front-on photo that looks like an impossibility. That bridge also appears to be recessed? -if so the possibility of filling the holes and repositioning it is also out....
It is a bolt-on but unlike a Fender style neck pocket there appears to be no room for movement in these. And all your other points are spot on. I find it funny that a lower-tech design like a Fender neck pocket would be an advantage in this case. As I said to the wife today, if I was able to get it even a little better without too much effort or expense I'd buy it.
I own two of these and can confirm the weird offset on both, maybe it's intentional. I also have to say I never noticed it until you pointed it out in this thread so I guess it's never affected playability for me. I'm a pretty reserved type of player these days, though if I was still whaling (wailing?) on bass guitars like I used to it would probably be a problem. I play three different bass guitars and don't have any trouble switching to/from this one. Good luck!
I found a local guitar builder to install DiMarzio's I've had sitting around since the '90's. He routed the body, added some wood blocks to support the pickups, installed a Fishman Power Chip, pickup selector switch, new volume knob for the EM pickups, set the piezo/EM balance, and that was it. Here's a link to the Fishman Power Chip (which is what makes time travel possible): https://www.fishman.com/portfolio/powerchip/ Looks like they're going for $109.00 here in the US. He also had to replace the input jack, I don't recall exactly what product he used but I can find out if you want. If I recall correctly he charged me three hundred including the hardware but did say later he found another (non-Fishman) system he'd like to try if we do it again. FYI - the rhythm track in the video I posted is piezo @ 100% and EM @ 90% with no effects, the melody is piezo @ 100% and EM @ 0% plus chorus. I hope this helps, bass on.
I have a 5 string and it doesn't seem to have that problem. Weird thing, on the fours. Looks like the bridge wasn't well positioned.
