Finished another one (Formula rewire)

So I have this Hondo "Formula" (think fake Ibby Roadstar)

I'd always wanted one of this generation of Roadstar (between when they were a slightly weird Strat clone, and before they went full on Shred machine)
I saw this one on Ebay, bid on it and got outbid right away. I also saw one on Reverb, and bid on that one too. Somehow I managed to "win" both of them...

I thought of taking them both apart, to make one good one out of them. However, one of them was clearly heavier, had a skinnier neck and more buckle rash. So I ended up just keeping the good one.

It's Ash, with an Ash top and Maple/Rosewood neck. It came with (tarnished) Gold hardware, Grover tuners and a Schaller bridge (which was chrome, which I thought looked kinda weird with all the Gold, but whatever) The pups were nice sounding, not cheap or muddy so I just played it. I did want to mod it though...


First thing, I took off and sold the tuners and pickups. I got a set of Chrome Grovers, thinking they'd just drop in... nope.


I had to fill the tuner screws, and drill new ones.

I think I did OK, you can barely see where I did it. I don't know if they were different because they changed in the last 30 years, or I accidentally got fake ones, or the new ones are Chinese or something. Whatever, the old ones were all crungy looking and these new ones turn a lot smoother. I would have just gotten the Kluson-style ones I like if I knew I'd be filling and redrilling.

The string trees (or whatever the circle things are called) and the truss rod adjust are still Gold, I would like to change those, but not if I'll be drilling again. (The strap buttons are still Gold, too, and somehow I only have one chrome one... god knows why...)

The next step was the tone circuit. I sold the pups, mostly because they looked nicely aged, instead of the super fake "relic" stuff I'd seen. I figured somebody'd want them, they weren't name brand or anything, but had 30 years of honest wear on them.

A guy bought them, then asked for a return because they "didn't look authentic". :rolleyes: Whatever, it was $20 so I did it. He didn't want to return them though...
Anyway, I had always planned to get double cream Dimarzios for this, because I grew up in the 70's/80's, and when you bought new pups for your HOndo, that's what you got. Plus, I think nuthin' looks better on Cherry Sunburst than double creams. I know the colors don't matter, I just wanted them.

What I got was a "36th Anniversary" in the neck, and a "Tone Zone" in the bridge. I also got a pair of their 500K pots, a Switchcraft 3-way, long-shaft output and a pair of on/on/on mini toggles for crazy switching. (My Skylark has spoiled me, I dig lots of switches now)
Originally, the guitar just had cheap mini pots and a "box" switch

They also didn't drill out the control cavity all the way. (Hey, it IS a Hondo, I shouldn't have been suprised)
So I borrowed my mother-in-law's wood shop and opened up the cavity

Instead of using the copper tape like usual, I decided to try the Sheilding paint. It went in waaaay faster than taping the cavity would have been (duh)

The holes for the pup wiring wasn't big enough for the 4-conductor pups I now have, so I got to use the "Aircraft bit" I bought years ago for a different project. Yay, now I've drilled TWO holes with it!

And I managed to not drill a hole thru the top.
I did a bunch of measuring to figure out where to put the holes for the mini switches. And then ended up just free handing them.

If I was doing this again, I'd probably put them elsewhere, but it turned out fine.

I did have to ream out all the original holes, since my new components were all bigger than the cheap stuff I took out. I had to open up the pup routs a little too, because the new pups were juuuust a bit wider than the originals.

The top is thick-ish, and carved so the 3-way didn't protrude enough to screw the washer onto it. I had to get out the Dremel router and make a thinner spot for the 3-way.

THat's better!

Now it was time to wire everything up. I spent a few hours doing that today, my head still hurts from either the solder fumes, or wearing 2 pairs of glasses so my stupid old eyes could see what I was doing (no pics of that, thank goodness)

Either I'm getting better at this, or I forgot a bunch of stuff... this looks too neat to be something I hacked together!

I ran out of solder halfway thru, so I checked out the Radio Shack in the town I live in. Well, they now sell "Vaping" stuff, no solder there! I ended up at the Ace hardware, where I should have gone in the first place.

I got it all together, strung it up and it actually works! I don't know why I'm so suprised when that happens...

Actually, the original knobs don't fit on the pot shafts, so I have to order new ones. And maybe some strap buttons. BUt it's done!

I love everything about that guitar. The style, the finish and especially the great job you did with the electronics.
 
Re: Finished another one (Formula rewire)

Man I was digging this thing the last couple days, and now the neck pup isn't doing anything. THe bridge works just fine, but the neck acts like it's dead. Now I gotta take it all apart and figure out what I did wrong. But I'm having too much fun with it to rip it all apart again...

The 3-way acts like a normal switch, and the 2 mini toggles go from split bucker, to parallel HB and series HB, so I get 3 different sounds from the switches. The series HB is full, fat HB tone. Both the other settings are nice, but I really love the full-on bucker tone I get. I seem to use the middle/both pups on setting the most on all my guitars, so I had been excited to hear what this one was gonna do in that setting. Bummer. Also, I really want to hear what this thing sounds like compared to my "real" LP, as far as fat HB tones. My tele with HB's (Gibson mini-HB/SD JB-Jr) sounds nothing like this guitar!
Oh, and I got real knobs finally, but now I realize I have the pots jacked way up in the cavity (the shafts stick WAY up off the guitar top) so maybe that will give me an excuse to pull this apart again.
