‘The Electric Spanish Guitar’
(Quote taken from the 1940’s Brochure)
Hi All,
Well, as suggested last time a National it sure is ... but not what you’d expect!
National have an interesting history taking in Hawaiian music, blues, dance bands, the fall out of favour due to the new fangled witchcraft thing called an electric guitar right up to the National Resophonic Guitar company who make (in my opinion) some of the finest guitars I’ve ever inspected and indeed ever to leave the USA.
A good friend and customer asked me check over a guitar he has, when he said National I’d got the metal work kit ready for a steel guitar but is a lovely old ‘f’ hole jazz guitar. The give away being I think National stopped production of steels at the start of the 1940’s and we believe this guitar is from 1950.
Next time it’s in we’re changing the odd tremolo arrangement for a more standard tail piece this will improve the down pressure on the bridge (also to be replaced) ... and take the fear out of having a tremolo on an old body with no centre block to support it.
The frets have been ground right down by some previous owner almost to the fingerboard but work fine and the intonation is surprisingly very good.
So what have I done?
Under the instruction to leave pretty much ‘as is’ for now warts and all I have improved the neck relief (it was too much) simply by dropping down a gauge of string as there’s no truss rod, in turn this meant the bridge had to be raised a little, this then meant the string break angle over the bridge was slightly improved, it’s still too shallow really as the tremolo unit ejects the stings quite high with no second bar to hold them down like a Bigsby.
I’ve also balanced the 1st fret action just by filing a little material out as required.
Frets, with so little fret they’ve just had a light Polish there’s no big trenches in them and although a bit rough they work / play surprising well, the dry fingerboard has also had a good feed.
I’ve checked a cleaned the electric bits tested earth etc. and even just through the little workshop test amp it sounded well!
Intonation was set using low tack tape before removing the bridge to give a guide later, then set and checked on the strobe tuner ... and my ears!
A good clean with the Beard guitar Polish and she was looking swell!
Couple of tips for working on old or vintage guitars.
- Use a non- abrasive metal polish on metal parts.
- Unless you have some experience with working on old guitars when changing strings do one at a time.
- Use a good polish preferably one (like Beards) with no chemicals at all.
- If you have to change any parts keep the old ones - a future owner may want them.
- As much as possible maintain a respectable humidity level and temperature (as with any guitar - I’ll do a piece on this later in the year)
- A case is a good idea!
I’ll add a few snaps below showing how it went and what this great guitar looks like!
Thanks for looking in
