Hello Everyone, New user here. Recently bought my first electric (played only acoustics before) which happens to be the HB ST-70 Black Paisley.
Nice axe for the price. My sample was not the best one with high action to hide buzzing frets when lowered to anything below 2.2-2.5mm on low-E @17th fret. But everything else seems to be ok, at least from my newbie perspective. So I've decided to keep it as a kind of DIY improvement project, which will include: fret leveling, locking tuners, plastic nut -> TUSQ (will have to cut it on my own as their pre-cut ST nuts are not an exact fit for this model), shielding the cavities and upgrading the electronics (PUs will probably stay the same for now).
Having found good info on most of the aforementioned items, I'm struggling a bit with the wiring/pots/caps/... I would be very grateful if an owner of the same model or anyone else with experience will help me with the following: 1) Does anyone have the wiring schematic for this particular HSS setup with push/pull volume for coil split. 2) What combination of pots is used here (i suspect it's something like 500K volume + 250k tone for SC and 500k tone for HB). I assume they are all audio/log type. I'd like to order the parts before I start the work, so I can't take a good look inside without wasting a set of strings. 3) How many and what caps are used? 4) Any recommendations on the switches? (Oak Grigsby or "Import" style?)
Thanks again)

Don't know if this is of any use to you?

Don't know if this is of any use to you? Thanks, That's closer, but not the same config I am searching for (1 push/pull vol, 1 tone for Neck, 1 Middle (No Tone for HB)). Main question would probably be the caps and pots for such wiring (500K or 250K and where). The scheme I can just copy when I open the instrument to do the work. I will probably email the guy from the video)

Sorry can't help you with the push pull pot values or caps, never used them. There is a Seymore Duncan site you can go on for wiring diagrams, it allows you to type in what pup set up you want then gives you a wiring diagram. Haven't got a link to it but if you Google Seymore Duncan wiring diagram you should find it.

Already been there earlier, but somehow missed the desired HSS P/P config in the dropdown list and thought that it wasn't there. Unfortunately there's no pot info in their schemes (probably they consider it a matter of personal preference or common knowledge), will email them regarding that. At least the cap is labeled.

I'm sure some of the other guys on here will know about the push pull pot values. It seems a bit strange they give a cap rating without pot value?. I've always gone by 250k pot for single coil 0.047 cap, 500k pot for humbuckers 0.022 cap. You can use different cap ratings on either depending on personal preference. I've used a 0.033 on a P90 single coil. I really don't know what pot value or cap is best for split coils.

It probably also depends on the wiring and tone functions. So far I've found that for HSS you can use 500K volume and 250K(SC) + 500K(HB) pots, with 470K resistors in single coil positions, so the PUs see the volume as 250K, and HB will see the 500K. But theses schemes don't involve the push/pull which might change the wiring and parts. And if I'm not mistaken ST-70 BP wiring has the independent tone controls for singles, and HB is not tone-controlled at all (will have to check again), so it may also affect the choices. Well, it looks like I'll have to take a look inside after all to be 100% sure.

I'm sure you will get some of the other lads reply over next couple of days, who have experience with split coil set ups. Sunday night can be a bit quiet.

I can't help as I always buy ready made drop in harness from eBay, usually solder free My bridge bucker is the DiMarzio Cruiser in single coil format and simply shares the 250K with the rest of the single coil pups of my ST-62MN. Sounds great!
