Charvel San Dimas I USA Koa project

MkIII Renegade

New member
I picked up a very rare USA San Dimas in need of some TLC. I could tell the body/neck/fretboard were in great shape, so considering that I have lusted for one of these since 1995, I excused the partially corroded hardware including the top 3 Floyd saddles and trem bar (corrosion wasn't really evident from the auction pics and was not mentioned at all by the seller :headache: ). I don't know if the previous owner either lived in a salt water cave or had toxic skin, but thankfully my skin doesn't assault metal, and if it did, I would wipe it down every time after playing rather than allow it to harm an expensive guitar! Some people....... Even the pickup mounting screws have some corrosion, so I am going to replace them as well. This is a #1 level guitar, so I'm not going to put up with any failsauce!

Quick summary:

Nice thick Koa Body
Bird's Eye Maple neck with Pau Ferro fretboard and 24 giant frets :D
Jackson Schaller Floyd
Unknown hot Duncan pickups (will find out when I remove the trem/strings, might be Distortion + 59). Whatever they case, they won't do crystal clean, so I will do a push-pull coil tap for the volume knob to help.
The guitar has a very beefy natural sound, as you'd expect

Most of my guitars are listed in my sig. I like a very wide range of '60s - '80s rock most, with forays into anything from early Pink Floyd to Classic Prog to Prog Metal to '80s Thrash to early VH influenced Cock Rock, etc. Also an Al di Meola fan. I like a very responsive, lean, mean, articulate bridge pickup with a rich, full, but more mellow neck pickup as is typical. The middle position, both HBs tapped sound is my favorite clean sound by far for HH guitars. My essential sound is a whatever guitar I have plugged straight into a Mesa Mark III or IV.

Asking for some opinions on the following:

1. Instead of replacing saddles on the Schaller Jackson Floyd (very good), I was thinking of getting an Original Floyd (best), but I know the screws that protrude from the back are way too long for the cavity behind the trem. That brings me to the Original Floyd Rose Pro (low profile), which LOOKS like it should fit and I assume would otherwise mount where the Schaller once was. Has anyone tried this in a Jackson/Charvel that originally came with their branded Schaller trem?

2. Thoughts on new passive pickups? Not doing EMGs for this one, and I already have most of the pickup combos I've ever wanted, so perhaps something different like Bareknuckles? Big fan of various Duncans and Dimarzios (other than the flabby Tone Zone), and as a bonus, they don't cost $350 for a pair! I live for fast alt-picked runs high on the fretboard with the neck pickup and like a pronounced pick attack.

3. Thoughts on tone blocks? I'm not going to spend $150 on tungsten. :laugh2: But I might consider a brass block or similar. This guitar already sounds very big and nicely balanced, but even more of the same would be fine.

Wowzers!

Brass blocks come stock on OFRs and Schallers. Want more of the same? Turn it up LOUDER.

If a big block can improve and amplify the natural tone, you'll hear the improvement through the amp at a given volume, even at 11!! :D

I've heard testimony from quite a few who swear by big blocks, but then again I also know that we survived for many decades with old fashioned dinky blocks. I'll get some more pics of the cavity later.

A heavy block can't really amplify anything by itself ;) It is just dead weight hung onto the bridge, swaying back and forth like a pendulum, set into motion by strings. Personally, I don't like heavy ass blocks on my Floyds, because they take away the bite and the guitar body's response to subtle kind of playing, light picking, natural and tapped harmonics etc, and kind of dull the resonance, neuter the snap and the shimmering harmonics. I bet I'd love them if I were into doom/sludge or thin and stiff Ibanez guitars or sustain-dick-measuring-contests. To be honest, I'm into neither. I hope to try a lightweight titanium block one day.

But then I acknowledge you might be of a totally opposite opinion, and of course, your guitar will respond slightly differently to mine and it is going to be played and enjoyed by you. Fat brass blocks are not super expensive, right? Worst thing that can happen is the guitar becoming woofy and kind of honky. A block swap is non-destructive and reversible anyway, so yeah, you might wanna give it a try.

E: Oh ****, I forgot... Happy NGD! :beerchug:

This is the kind of personal big block review I've been looking for! I'm not willing to give up the subtle but important things you described simply for a little more ooomph. Maybe if I can play a guitar with one installed I could be persuaded, but I'm not convinced yet.

Even though the guitar needs a full setup, I instantly fell in love with the feel of it! I almost think of this as a rescue and restoration project. The potential is huge, can't wait to get everything sorted and spend some quality time with it! Will do a NGD thread at that time. :D

I can confirm that the stock brass block is best for OFR. The big block kills the harmonic content but has stronger fundamental tone. A shredder will want the standard brass.

I am partial to Evolutions and Full Shreds. Also check out the Dean Equalizer which is another pickup along these lines.
 
Re: Charvel San Dimas I USA Koa project

If that trem stays in tune, why replace it? Maybe get some new saddles/bar, sharpen the edges and call it a day.

There are a few other trem parts in need of replacement as well for the guitar to be mint. Since I'm treating this as a #1 guitar (actually I have several guitars I think of as co-#1s :D ), I am willing to go all out and get a new OFR Pro. Although I think the Schaller is excellent, my other San Dimas has a standard OFR and it feels even better to me, if only slightly. I've seen several testimonies at this point and think the standard Floyd block will be just fine.

Finally got some time to play again last night in various settings and the pickups sound great, so maybe a push-pull coil tap for super cleans will do for that. But I dunno, will have to think hardest about the pickup change, if any.

I have to admit, one of my fave things about the guitar so far has been the reaction of others when they see it. :cool: It is rare and has lots of mojo, I'm stoked!!
 
Re: Charvel San Dimas I USA Koa project

At least it appears to have a real locking nut. My first two Charvels had a locking nut behind the nut, which was a really bad design.
 
Re: Charvel San Dimas I USA Koa project

Awesome guitar!!! I have a Japanese Pro mod Charvel and a US Custom shop. Ive put big brass blocks on both and feel the improvement well worth it. for pickups, my pro mod has a Duncan Jazz and the new hybrid pup (TB15) in it and it sounds killer and the US one, I changed the Custom to a custom 8 and has the Jazz in the neck

After doing some research, I'm leaning toward the alnico BK Nailbomb (b) and Cold Sweat (n). This seems to be a popular combo and should be able to provide crystal cleans with coil tapping just like my Duncan Distortion/'59 do in my other koa guitar, especially for my favorite HH clean position, the inner coils of both humbuckers only.

Anyone played this combo? Seems like the Nailbomb Neck model probably wouldn't clean up as well as the Cold Sweat, which is why I probably won't get the set.
 
Re: Charvel San Dimas I USA Koa project

Nice score dude! I love Koa! would love to see some better pics of it, (front and back) as well as a Koa family shot!
 
Re: Charvel San Dimas I USA Koa project

Longterm update. I bought (well attempted to buy) the BK Nailbomb/Cold Sweat combo, and the deadbeat vendor disappeared with my money, but never delivered the pickups and wouldn't answer my calls. I got my money back through my credit card company (he never responded), although I'm not done with him yet (at the very least, I will let BK know how he treats their customers). But that's another discussion. Aside from that unpleasant distraction, I also started a new (and very demanding) job, so the project has been on the back burner.

I resolved my corroded Floyd problem by replacing all the needed parts with new genuine Floyd parts and cleaning the rest with jewelry cleaner. I bought a 34mm big brass block, which is not a "massive" block, but a bit more than standard. If I don't like it, I can always goes back.

My current finalists are still the Nailbomb bridge (c) + Cold Sweat neck pickups, and the Dimarzio Crunch Lab + Liquifire. My only reservation about the BKs (aside from the very negative vendor experience) is that they cost more than twice as much as the Dimarzio setup due to the exchange rate, although cost isn't an issue if they are truly special.

My only reservations about the Crunch Lab are the somewhat industrial appearance of the bar magnet (yes appearance matters, especially for this, probably my most beautiful electric) and that it may be overly fat sounding (not that it would lack clarity, but edge), although I doubt that would really be an issue. I would start out with the generally accepted bar toward the neck orientation. I have NO doubt whatsoever I would love the Liquifire since it's based on the Air Norton, one of my fave neck pickups ever, especially for soloing. In fact, I would even consider another toasty Dimarzio bridge pickup to match it, but WHICH ONE? The Duncan Distortion is my benchmark for great crunch and lead, although traditional Duncans are already well represented in my arsenal.

Since buying the guitar, I've heard of the new Illuminators, but I don't know that they truly represent a step forward from the CL/LF, if anything, maybe a bit more clarity at the cost of warmth?

This guitar will have to clean up very well (l like crystal clean) and be capable of less-metallic sounds at times, although most of my playing is rather hot-rodded, so I want an aggressive overall setup. I am mostly '80s/early '90s metal oriented, with an appreciation for some prog elements. I play Eb 99% of the time, with drop D maybe every other blue moon. I will sometimes do Hendrixy psycho jams (or Floyd/Syd Barrett interstellar freakouts, especially with the Tele), but never straightup "old white guy wanker blues", so I'm not concerned with that.

I had the same setup in a Jackson and loved the Liquifire but did not care for the Crunch Lab. I would HIGHLY recommend you put the Liquifire in the neck and a SH-12 Screamin' Demon in the bridge. IMO, the SH-12 is a huge step up to the Crunch Lab...the SH-12 sounds better clean than the Crunch Lab and I personally get better pinch harmonics out of the SH-12 than the Crunch Lab.

Edit: I currently have the Liquifire and SH-12 setup in a Ibanez Iceman, one of my best recording guitars.
