10 String Lap Steel






Towards the end of last year I got a call asking if I could make a 10 string lap steel guitar. Why not I thought.

 In their simplest form lap steels are very simple.

 I wanted to be a tad more sophisticated with mine. This might be a simple instrument but the components and construction still make a difference to the sound. It's a fretless electric guitar with a high action - the wood, bridge, nut and electronics are just as important as for a LesPaul or Stratocaster. Well that's how I look at it anyway.
 I decided to design it with a cool old traditional vibe - Empire State meets LeMans which sounds like I'm mixing my decades but there's a boldness of line in common that I like.



 I combined 2 woods, Paulownia and Australian Blackwood.
 I wanted a hard wood (Blackwood) to both emphasize the high frequencies and help transmit vibrations along the instrument and help it sustain. It gives it structural strength too.
 The soft Paulownia is great for lower frequencies, warms up the bass and mids and adds an almost reverb like quality to the note.
 Blackwood on its own would make a harsh sounding heavy instrument with too much treble, Paulownia on its own, wooly and undefined without enough structural strength. But together, they really work.
 They give a nice colour contrast too with the darker stripes running right through the instrument.
 For the fingerboard I chose a piece of Swamp Kauri (https://en.wikipedia.org/wiki/Swamp_kauri). This is one of the oldest workable timbers in the world. I don't know how old this piece is, I'd need to get it carbon dated, lets just say a few thousand years. It's frequencies lie between the other two woods and it's a beautiful colour. It gives the player something pretty to look at. We're lucky here in NZ to have some fantastic timbers. I inlayed fret markers and some chequered stripes into it.




I chose aluminium for bridge and nut, it has a lively, quick response. Steel feels like it reacts slower. I think that extra mass just takes more string energy to get it moving. I used long screws to mount the bridge deep into the wood - that coupling is important.
 I made the P90 style pickup from scratch using alnicoII magnets and fibre board. I wound it as I would a conventional P90, ties the ends off and then wound a couple of thousand extra turns of thin wire on top.
Using a switch the extra turns can be added. So it can go from a traditional chiming pure sound to a grunty, dirty powerful blues tone at the flick of a switch - two pickups in one.
 I got the pickup cover 3D printed, remember this is a 10 string, parts just aren't available.




  I had the decals made up in a groovy font - I usually inlay my guitars but the decal suited this one better.




 I finished it in shellac so as not to stifle any of the sound I'd worked hard to achieve.There's no point in making a light, resonant instrument and then stifling it with thick polyurethane just for the sake of ease.

 By now I'd gone way over the usual spec for a lap steel (I just can't help myself) but I do think it's an instrument that needs to be taken more seriously.
 I'd come in exactly on budget but a week over time.

He seemed pretty happy with the end result.

Multiscale Guitars - what's it all about?



Recently I've been making a few acoustic guitars. Some have been custom orders and some to have at the workshop for sale.
But until now I haven't made a multiscale guitar. I've been interested in multiscale guitars for a while but have never played one. I find the idea of them very appealing so I just had to try one out.


 As you can see the frets, nut and bridge are not parallel.
The idea behind it is so much more than a gimmick - there's a lot of sense in it.
It's all about scale length - the distance between nut and bridge.
Scale length plays a huge part in the tone of the guitar. To put it in electric guitar terms - ever wondered why a Strat and a Les Paul sound and feel so different? One of the main factors is scale length.

 A Strat has a longer scale length than a Les Paul (25.5 inch to 24.75inch). To tune a longer string to the same pitch it needs to be tighter. So a Strat has more string tension than a Les Paul for the same gauge strings in the same tuning.
 The result is, the bass strings of a Strat have a lovely chime where as the Les Paul bass strings can be a bit woolly (especially when tuned down).
 But the more taught treble strings of a Strat can be a bit pingy where as the Les Paul treble strings really sing.
 So it makes sense to build guitars with a combination of scales. PRS use a 25 inch scale length to try and get the best from both. But that doesn't solve the problem, it just compromises on both bass and treble.
I decided to build this guitar with a 25.625 bass string and a 24.75 treble with the scales converging at 12th fret.

 It's not a new idea - not at all, it's been around since the 16th century.

The guitar is constructed slightly differently to allow for the different scales. I've off set the internal braces and bridge plate.



 I carved the braces to free up the bass side and help the treble project.



The body is of Australian Blackwood,Cedar top and Mahogany neck with a traditional tapered dovetail neck/body joint. The headstock has been modified to accommodate the angled nut.





I use the traditional tapered dovetail neck/body joint.



And does it work? Well, ... yes.

I'm delighted with the result. The bass is clear, the treble is punchy but warm, there's a well balanced mid range.
 Having each strings at its ideal tension means it intonates superbly. - I'm chuffed.

From a players perspective - how does it feel? I imagined it would take a bit of getting used to, but not so. The biggest surprise has been how easy and natural it is to play.
 So far a few people have played it and they've all found it feels natural.
Dylan Kay (http://www.aucklandguitarschool.co.nz/) popped in the other day and he loved it.



This guitar is residing at my workshop (until someone buys it) - pop in for a play. And of course if you'd like a custom made guitar... (especially a multiscale)
 Cheers
