Here are a couple of 3D renderings of the CAD model. Solid modeling is fun as soon as you get the hang of it. It becomes so gratifying when you see the rendering taking shape. Ah yeah… the artist in me. The model is dimension-accurate (down to the screws). I do have a couple of unfinished actual prototypes as well as some actual parts (tuners, pickups, etc.) that I reverse-modeled.

The Body

The top is 4 layer carbon fiber (See Black Steel) with polished stainless steel binding (typically, luthiers use plastic). I am all for non-traditional designs, but this time, I’d like to start with a more conventional Strat-ish body design. I’d love to have more electronics installed (more on this later), but the basics must be set in place. For this design, that means 3 DiMarzio Area 69 pickups, standard 5 position lever switch, passive volume and tone controls, Schaller roller bridge and Grover locking tuners. Electronics fail and easily become obsolete. I want this creation to be alive and kicking, and still retain its value, 50 years or more into the future for the generations to come.

The top has a slight curvature (717 mm radius) as shown in the 4th image above. The bottom is aggressively contoured for ergonomics and for easy access to the higher frets. The image below shows the guitar’s back. The neck-thru construction eliminates the neck-body joint so we can be as radical as we can in sculpting the back.

Neck-thru construction

The neck runs through the full length of the strings up to the bridge and string ferrules. The string goes through the body (2nd picture below). It is constructed using bamboo-epoxy laminate (See The Mystical Plant) wrapped in 3 to 4 layers of carbon fiber. The truss-rod is also constructed from carbon fiber (unlike traditional guitars using steel rods). Like the body, the neck-thru sports polished stainless steel bindings around the fretboard and head.

This middle neck-thru piece is the most crucial part of the guitar. Like the classic Steinberger, the premise is that this middle section should sound good by itself. Unlike the Steinberger however, we will still have a head and a body. Like the Les Paul, the carbon fiber body top will enhance and project the guitar’s sound.

The Head and Fretboard

The logo and truss-rod cover are stainless steel inlaid into the 6-layer carbon fiber top. The fretboard has the same sandwiched carbon fiber-bamboo-carbon fiber construction. The fret position markers are back-lit with white LEDs with brightness adjustment.

Notes

  1. I like non-traditional designs. I usually prefer my own body styles, but this time, I’ll start with a more traditional Strat-influenced body design. The body will be more aggressively contoured though (more on that later).
  2. The “scale length” is the total length the string travels from the edge of the nut up to the center of the 12th fret multiplied by 2. The scale length (among other things) affects the overall sound of the guitar. That is one reason why you can’t just install single coil pickups in a short-scale guitar and expect it to sound like a Strat. The scale length (644 mm, 25.35″) falls somewhere in between a Strat (647.7 mm, 25.5″) and a Les Paul (628.65 mm, 24.75″).

Flashback

Yeah, that’s me, more than 20 years ago. That’s the first guitar that I built when I was in high school almost 30 years ago. The body is reminiscent of the Gibson Explorer blended with the Ibanez Iceman. I love the balance and feel of this guitar. The neck has a unique  23.5 inch scale (shorter than a Gibson Les Paul) with 24 frets, making it very easy to play lead. The tremolo was handcrafted, milled from solid brass and gold plated. It can bend up 6 semitones and down until the strings are loose; it’s a locking trem with perfect center return. Back then, I’ve seen locking floyd rose trems only in magazines. I had to build a locking trem myself.

The guitar is equipped with a Seymour Duncan PU at the bridge and a Dimarzio at the neck (can’t recall which models). Don’t go telling me I can’t combine these pickups! I think outside the box, remember? I’m never constrained with preconceived notions of what should and what should not be done.

Alas, this guitar was stolen. Now, what’s left are a just couple of pictures and memories. What’s important though is the experience I had building the guitar. Since then, there’s this lingering urge to build instruments that reflect my soul. This guitar is like no other and has its totally unique sound – its signature.

Now, everyone wants a Stratocaster. Bah!

As always, it all starts with a good design. I can be a hacker. Sometimes I am. But for projects I love most, the perfectionist in me insists on starting with a good design. I actually did some drafting work initially using plain ol’ rulers, triangles, pencil, pen and paper. I still have some blue prints somewhere. Yet, there’s always this itch to design using modern tools: 3D Solid Modeling! It makes perfect sense!

While my guitar gently weeps

Technically, this is not a solid-body guitar. The cavity essentially makes this an acoustic-electric guitar. The objective is to control and actually take advantage of the inherent body resonance. This guitar will be designed with feedback in mind, especially for low sound level/volume, studio use. I love singing and weeping guitars that sustain indefinitely with controlled feedback. This usually means cranking the volume up to 11: the hallmark of Hendrix et al. I love this effect, but I love my ears too and so I wish to achieve this effect at much lower volume levels.

The central thru-neck piece is a single piece, solid, select  bamboo – epoxy laminate, wrapped in carbon fiber for added rigidity. The truss rod is adjustable and likewise made from carbon fiber. The body and head tops are made from 4 layer carbon fiber/epoxy laminate with 0.5 mm stainless steel binding.

More on the design later…
