Long story short, since I never updated on this. I got ridiculously attached to the Spectrum in the first month I owned it. In the top 5 guitars I've played of all time, it's a weird guitar, but it suits me for some reason. It weighs nothing (this is why I bought it in the first place, I needed something light to rock a higher strap length, since the explorer is at perma thrash height) and the neck is effortless and it has a nice airy/twangy tone.
Pretty much nothing on it is original. Perpetual project. I've done
-Fretboard Darkened, didn't bother masking cause who cares, ran all over the back of the neck, was an excellent excuse to lightly sand the neck to remove the gloss/dye and now it feels even better
-neck pickup not wired, the bridge and middle give me everything I need and that position being dead is handy to kill the signal with a quick flick. The only thing blade switches have going for them over toggles if you wire a dead position at one of the extremes.
I absolutely loved how the single coil sounded, but the amount of drive required to get it there made everything unbearably noisey. I love my Maxon OD808 to death, but it would need serious noise suppression, and I'm not really into that. It's also my main backup for the Explorer, so they need similar outputs, and the SAs are maybe half as loud as the 81.
So my options were, route it for a humbucker in the bridge, get a whole new set of passives, or get the Seymour Duncan Blackout single. None of those were any good, and it's such a quirky guitar that it would have been a crime to route it. So I looked into getting one of the EMG boost units.
Got one new for $30 on Reverb, Popped it in, and holy shit, every guitar should have one of those. I remember some highly regarded players having them in passive setups of other brands, and at the time I thought it was hokey. But it works amazingly with single coils. Highly recommended for SSS guitars. Anyways, check it out if you haven't and you wanna save space on your pedalboard, these are rad.
