Yeah, there is not much need for a barrel jack, especially on a hollow, but it looks fine and accurate on the body
I would not say that the bass is very quiet, but will try to get the humbuckers a bit higher...

I put a metal ruler on the fretboard and it seems, that it is not totally even and flat, like having slightly waves, maybe two, about 3th-5th fret and somewhere between 8th-9th...should have checked right at the beginning of the build...lesson learned
I adjusted the trusrod in the concave direction a bit and it got better with the rattling...I am afraid the sanding is inevitable
But I can't bring myself to do it at the moment, so I will give it some rest

Wanted to order a sandblock for the fretboard, but how do you define the radius usually? fender3x, you said 12", I would order that one, but have no idea why this is right...
