So I got Rosetta the Starfire back today and man, I'm very happy.
My tech (Toni from Toni's Guitar Garage in Largs, South Australia) did a great job with the setup. Toni's set the intonation nice and low and light and it plays like butter.
I've had the original caps replaced with orange drops (and I know there are debates both sides on the benefits of these) and coupled with the treble bleed mod I'm finding the variations available across the volume and tone pots much more useable and less mud in the whole sound. Much sharper overall really.
Toni's even gone to the point of heat shrinking the orange drops in clear heat shrink which I thought was a great bit of attention to detail.
I haven't had the treble bleed mod done to the master volume as yet but a quick ten minutes with the guitar says that it will be worth it. I can roll off either of the volume controls now and all the way down to zero and there's a nice high end quality without things getting muddy. I can now leave my fuzz or octave fuzz on all the time and roll the volumes off for some great variations in sounds and small biting fizzy, farty tones, along with lower gain stuff which rolls on neatly into full blown fuzz.
I've had the pot layout adjusted too as I'm used to this setup on my Tele Deluxe and Tele Custom and it works well for me. Forward volume and tone is neck pickup, back volume and tone is rear pickup. Simple.
The nut has been replaced with a Graphtech TUSQ XL. The two Godin's I've had for years both have these nuts as standard and I've never had issues with them. Toni suggested the TUSQ nut as I wanted a replacement as I was having issues with binding across the nut when tuning or using the Bigsby. Now I've noticed I can grab a handful of the Bigsby and it'll still hold tune really well with the roller bridge and change of nut.
And here's a picture of one of my favourite parts of the Starfire IV....because, why not? The lower bout holds a toggle for the pickup and master volume. It's the perfect spot for these and was one of the things that really sold this guitar to me.
And you know what? When I picked Rosetta up Toni said to me she had spent some time checking it out after intonating everything and was really blown away by it. Now she's got the works. Tele's, Les Pauls, J Mascis sig model, etc, etc. Probably 2 dozen guitars there. She told me she's now considering one of these Guilds. Her words were "Why would you want a 335?"
That's right. Why would you?
