Behold the Warmoth Gecko bass guitar (this one's Warmoth's....not mine)!
This will be the story of one man's journey from dreamer, to exasperated luthier, and, hopefully, onwards to a very satisfied, and proud, owner of a fully-custom Warmoth Gecko 5-string bass guitar.

You Only Get One Chance

I'm sure there are dozens of sayings like the carpenter's adage: "Measure twice, cut once".

The task of drilling the holes for the controls has been making me nervous ever since I placed my order for the body. There is no drilling a second set of holes if the first set isn't in the spot I wanted. How do I get the correct arc? How do I make sure everything will fit neatly in the cavity? How do I mark out the correct drill positions for the pots? These, and many other questions, are yet to be answered. Nevertheless, I have a plan!

A practise template!

I have made a plywood pattern of the control cavity profile.  The idea is to test the layout of the pots, preamp and switch, making sure that they don't get in the way of other parts, such as the input jack, or the pickup leads.

It looks to me as though the arc of the cavity along the lower edge matches, in places, the arc of the body. It also appears as though the control cavity cover has the same curve as the body To be honest, it seems pretty obvious, but I need to check (twice), to satisfy myself that this is, in fact, the case. Therefore, I should be able to use the cover for marking out the arc along which the controls are placed.

But then, there is still the alignment to work out, so that I do end up marking an arc as parallel to the body arc as possible. I'm thinking that the straight section under the battery compartment will have to be the datum.

This might take some time!

Making Sawdust at Last

The excuses have all run out. I'm finally underway. Tonight started "1.01 Drilling Holes for Strap Locks". By the end of the night, I had them fitted up.

Finding the place to drill was straightforward at the rear of the body, but a little trickier on the horn.

The rear strap lock is positioned at the centre of the body. The centre line of the body is the bookmark join line of the Swamp Ash core.



The hole was drilled as close to mid-thickness as I could establish. I had a caliper to measure across the body, then set a carpenter's square to half the measurement.





















For the hole on the horn, it was a bit of line-up-by-eye to follow the basic line/angle of the body, and then judge the middle point.

Drilling the actual holes proved more challenging than expected, as I had to put my tool box on top of the body to stop it pushing away. I have a soft blanket on the work bench to protect the wood, and I certainly had plenty of padding between body and toolbox.

One of the recommendations I came across was to apply soap to the screw threads to prevent lock-up and screw breakage. This is probably sound advice for harder woods, such as walnut or maple, but the Swamp Ash is comparatively soft. The screws went in slow, but steady, and tightened up nicely on the lock button. Certainly careful not to over-tighten, and strip out the wood.






















First job done! I don't think too many more tasks will be done and dusted in one session.

The Job Ahead

Most guys love a project. One of the things I enjoy about a project is mapping out the steps to completion. No assembly instructions come from Warmoth, probably because it would be impossible to be specific for each order. Disappointing at first, but reasonable, when you think of the huge range of end product achievable. This was the safety net I was searching for, but in the end, you just have to think it through as best you can.

While waiting the several months for my parts to arrive, the homework continued on how to go about the build. I looked up info on everything I could think of, and found some very helpful hints, tips and resources. The anticipation was also the final motivation needed to clean up the garage and create my "luthier's studio"!

Once the components had arrived, and some trial fitting (playing around, mucking about, call it what you will) had taken place, a plan starts to come together (I love it when a plan comes together!) and the sequence of events begins to take shape.

So, the following is my way forward.  The plan is not generic. It is for my specific project.

Let me say again, "Long-time planner, first-time bass builder".

The Parts List

The main parts of my kit,  the body and neck, came from Warmoth. The remaining instrument items that didn't come from Warmoth came from Best Bass Gear (BBG). The woodworking/finishing items are from a local supplier, Carbatec ( www.carbatec.com.au/ ).

All the parts were accumulated over several months, although I placed the orders for the body and neck at the same time.

Incidentally, another reason that made Warmoth so attractive is the current import tax/duty system in Australia. Orders of a value less that A$1,000 do not attract sales taxes and duties. So I placed two separate orders on Warmoth. One order for the body, plus some of the parts and then a second order for the neck and the remaining parts. Together they would have totalled more than the threshold. I don't believe there is any way you could directly import a finished instrument of similar quality for under A$1,000!

So, what follows is what I have to work with. This is the final specification and associated parts list. As far as I can tell, I don't need anything else, except for a case, and that is budgeted for. Any surprises will have to go through the financial controller first.

The Specification

I am simply a novice player and, before I started, had little idea regarding the art of guitar building, or how to select electronics and hardware. I am a little better informed now, but was looking for all the help on offer in speccing my new instrument. I certainly got some great advice along the way. Many thanks to Tom Konig (www.konigbassworx.com.au/), for help with choosing, and setting up for, the Delano pickups, and to Spike at Warmoth (www.warmoth.com/) for pretty much everything else.

 I expect this to be my only instrument for many years and so I want it to be something I can develop into, and something that is versatile in the range of tones that it is capable of. I had to take the time get the spec right.

With Warmoth you get to specify absolutely everything!

So after months of poring over every inch of the Warmoth website, I decided on how I was going to create my bass. Of all the options, I decided on something a bit special. Not a Precision, or a Jazz, or any of the other familiar styles. I am going to build the Warmoth Gecko 5, with a medium-width neck.
The body core is Swamp Ash with a unique choice Bubinga laminate top. This means I selected the exact piece of Bubinga from a range offered on the website. Bubinga was one of the woods that drew me to a Warwick Corvette in the first place, so that wasn't a difficult choice. The selected piece has fabulous figuring and symmetry and I'm hoping it will really pop out after the tung oil finishing treatment. You will also notice that there are no drilled holes for the controls. I wasn't sold on the standard Warmoth diamond pattern, so elected to do this task myself (no cost reduction to omit this process step, btw).

 Probably the decision that I agonised over most was with respect to getting the strings to line up over the pole pieces of the pickups. Having chosen the Delano pickup set, the question became one of ensuring that the string pitch from the bridge matched the pole pitch at the pup routing position. This is where the information and suggestions provided by Tom Konig was invaluable. The suggestion of his that has ended up giving me some peace of mind (up to now), was to create a full scale drawing of the arrangement of bridge, pickups and the strings over the top, through to the nut. To do this, I used the free Sketchup drawing software. (When I started, it was a Google product, now it is known as Trimble Sketchup).
It was this advice and the subsequent drawing (shown at left) that led me to opt for placing the bridge pickup in the "sweet spot" position. This moves the pickup away from the bridge, towards the neck. A further measure to ensure this string/pickup alignment was to choose the Hipshot Type "A" bridge, which allows for minimal side-to-side adjustment of the strings individually. I guess we'll find out soon enough if all these precautions work out as planned.

I chose a Wenge/Bubinga laminated neck with a Black Ebony fingerboard and stainless steel frets. Wenge was again a Warwick feature that I was interested in, but it was the information from Warmoth that convinced me that this was the way to go for this project. The ebony is for tone, durability and tradition. The stainless steel frets for durability and contrast with the Ebony fingerboard. The scale length on the Gecko is 35", which is an inch longer than the standard bass neck. This allows for the B-string to be tensioned a little more, avoiding the floppy nature of the low string on the standard scale. 
The peg head features matching Bubinga laminate, and there is additional Ebony veneer on the neck ramp, where it joins the body. A nice, quirky feature of the Warmoth Gecko bass is the nice lizard inlay, also in matching Bubinga veneer. The position markers are on the side of the neck.












The electronics are Delano "The Hybrid-5" pickups, with "Sonar 2" preamp (the full Delano saga in a  later post). The hardware is all black: bridge, tuners control knobs etc. I'm hoping it will all contrast nicely, for a cohesive and stylish look.

The full parts list will be in the next post.

In the Beginning


I learnt on, and am still playing, a loaner Yamaha BB300 4-string. Don't get me wrong, this is a very nice P-bass to start out on, and has met every (limited) challenge thrown at it in the time I've had the pleasure of it's company, yet there comes a time when your bass playing horizons start to widen.

I am fortunate to be allowed to play in our church band where we are covering a wide range of styles, from traditional rock/pop to funk, reggae, C&W and R&B. Playing with musicians of a high standard really lifts your own level.

For quite a while I had been thinking of taking the step up to a 5-string bass. For a very long time I had my heart set on a Warwick Corvette $$. Two features attracted me to the $$. The first is the use of fabulous woods in the construction. The second reason, the tonal range achieved through blending the humbucking pickups.

After much searching, both locally in Australia and offshore, I finally came to the realisation that this instrument was way out of my reach. To get the combinations I wanted would have been prohibitively expensive. So I started looking around at kits. It was then that I stumbled upon Warmoth and discovered that I might be able to achieve an instrument that not only my heart desires, but my head is prepared to pay for.

The words on the forums were overwhelmingly positive, about Warmoth’s product, so I thought, in the words of one of the great philosophers of our time, Jeremy Clarkson (look him up!), “How hard can it be?”

Why a Blog?

Well, after exploring across the interweb for assistance, although there is much knowledge to be shared regarding building a guitar from scratch, I couldn’t find a consolidated source that tackled a project such as this. This is not to say such a resource isn't out there, just that I didn't come across it. Therefore, I am hoping that by documenting my project, others may benefit from my experience.

Secondly, I’m hoping the immense pressures of providing copy to the blog will spur me on to a completion in the shortest reasonable time, rather than become the excruciatingly long project that I have become well known for. And I'm sure that at some stage along the journey, a bit of  encouragement and advice won't go astray.
