GR-1SF Archtop Part 1

[michaelgard]

Hey all, this is my first Kit Build, also my first hollow body, first archtop etc. I've built a few solid bodys from scratch with an eye to one day attempting a hollow body based on this, which I'll tackle one day.

My last scratch build was a double cut-away based on a Duesenberg solid. I used all genuine Duesenberg hardware and parts apart from the Schaller roller bridge with adjustable string spread. It was a through body stringing and it played very nicely through my Laney 30W valve amp. I've now cannibalised that guitar to use the hardware on my GR-1SF build and happy that I bought the particular Schaller bridge as the Tune-o-matic type bridge supplied with the kit is patently unsuited for use with a tremolo. I'm intending to also use the electrics from my Doozy build in the GR-1SF too. Completely in the dark whether the components will suit my build. I guess ill have to fill some pot holes or put fake pots in.
So, off I go - intrepidly - to the great unknown.
Cheers
Mike

The copper shielding tape won't be much use on this build. It's only of any use where you can create a pretty much sealed enclosure with it. In a hollow body guitar, there's no way to do that. Using screened cables for the longer runs will help, but singles for the short distances is normally fine. But with both pickups being humbuckers, you shouldn't really have any problem with hum (just don't forget to ground the trem).

I've just discovered Pure Tone output jacks. Whilst I've always used Switchcraft jacks before, I'm switching over to these as they are a better jack socket. https://puretonetechnologies.com/pro...tput-jack-gold

All the best with the build.

Thanks for the copper tape tip, Simon. I was wondering if it would be necessary. Will be checking out the Pure tone Jacks.

I’m baaack.

Onto the wiring after a few months away from it all.
Looking at the alternative wiring diagram, it shows a green Cap at the master tone Pot. My package came with 2 tiny brown Caps but not the green. Does anyone know what capacitance the green cap is and the brown ones? Should I buy one to match the green cap?
Thanks if you can help.
