1st build - ESP-1

[Freak_Hybrid]

Since the last post i've sanded to 2000, polished it to a shine, levelled the frets, wired up the pickups and let loose.

I'm loving the look (Though i'm waiting on a new black bridge), the pickup sound is great and the neck isn't sticky but i'm having problems with the setup and buzz. Specifically, i can't achieve a low action and not get every fret buzzing. I've got the feeler gauges and the such (All the gear, no idea) but can't seem to find anything definitive online about setup measurements (Current measurements at the bottom). Any advice welcome.

I need to adjust the bridge/saddle posts as i'm at the lowest adjustment on the high e before the post bottoms out, i'm thinking when my new bridge arrives i'll recess the post hole slightly so the post holder sits ~1mm lower.

I'm going to buy new plastic housings for the pickups too as they're for an LP and so are angled and don't look right w/ the flat body. The battery in the pickup cavity is strapped in, i just didn't have a photo and am too lazy to remove the back plate.

I also think the nut is too tall but haven't filed it yet, thought i'd seek advice first.

I think i levelled the frets correctly (levelling ruler thing is off screen). I'm hoping there's just a sweet spot with the setup i'm missing and it's not to do with the neck angle as removing that would be disheartening (I didn't sand it before gluing so it's at factory height/angle)

Current setup gives buzzing all over. (All measurements taken in playing position)
relief: Cappod 1st fret, fretted @22 (Last fret), 12th fret = 0.01", 0.25mm
Cappod 1st fret, fretted @ neck meets body 19th, 7th fret = 0.014", 0.35mm
Action: 12th fret high e height = 2mm,
12th fret low E 2.2mm
1st fret to nut = 1.1 mm

Running w/ 9's, i need light strings and a low action or my left hand can't move the strings. Before my crash i loved heavier strings for the tone but currently even bending w/ 9's is out of the question.

PS: The EMGs i bought didn't require a bridge ground but thanks for the heads up. I was sure i read it somewhere but went back to double check.
