Reverend 'Warhawk' set-up



I do a lot of work for 'poolside studios'. They importvarious makes of musical stuff including 'Top Hat' amps, 'Eastwood' guitars and 'Reverend' guitars. All their guitars that come into New Zealand get checked over by me first. Not all importers care enough to do this. You can find Poolside at http://www.poolsidestudios.co.nz/ Today I've got a 'Reverend Warhawk' on the bench to check over.



Its a bolt neck fixed bridge electric guitar with two P90 pickups. My photo just doesn't do the colour justice. Reverend guitars are all well built they've got comfy deep necks, feel solid and lively, ballance great on a strap and sound fantastic as well as looking cool. Its not often I get this excited abouta new brand but the folk at Reverend seem to have got it right. This one was in tune out of the box and only needed a couple of small adjustments. One of the many factors that determin playability and a good action is the depth of the nut slots. If they're too deep the open strings will buzz, too high and its going to be hard to play especially for first position chords.

The best method for checking nut height is to place your finger between 2nd and 3rd fret pushing the string down as if fretting 2nd. Then look at the gap between the string and 1st fret. There should be a gap but it should be extremely small(about 1/4mm). On the bass strings the gap can be a bit bigger. On this guitar the gap was a bit big so the slots needed to be deepened.
I've seen this job done with all sorts of tools including hacksaw blades and kitcken knives. There's only one correct tool and thats a nut file. These files come in different thicknesses for each string and are round in profile. The bottom of the slot needs to be smooth and rounded. A 'V' slot will grip the string causing tuning problems and string breakage as will a square bottomed slot. In my experience most cases of tuning probsare caused by the nut.
This pic shows me cutting the nut. Note the angle of the file. If you cut slots too shallow (parallel to the fingerboard) the string can rattle about in the slot. Once the nut is cut the slots need lubricating, I prefere candle wax for this but pencil graphite is just as good. This was the only real set up fault with this Reverend. Check out NZ Musician's review (May 07) of Reverend. The review one I didn't have to do anything on- just checked it and all was fine. That one is fitted with a Wilkinson trem and had three P90's. It stayed in tune just great no matter how much cack handed Van Halen I threw at it.

All that was left was to raise the pickup height atouch and it was ready. Its so satisfying working on well made instruments.

Yamaha FG-260 12-string


This is a lovely old guitar that came to me with an unplayable action. 12 string guitars often suffer from problems related to string tension and this one had really suffered. The top was bellying and needed the bridge plate replacing - I'll go into that one at a later date. Even with the top stable and the belly reduced the action was still too high. The bridge saddle was right down low so it wasn't going to be an easy one.The neck had to be re-set. Over years the neck had moved with string tension and was now leaning forward a little. This was giving the guitar too high an action. There are a few ways to re-angle a neck; the traditional way is to completely remove the neck from its socket and re-cut the dovetail joint to the correctangle. The main problem with this is damage to the finish around the heel. I chose a different way - its called 'slipping the block'. With this method the neck stays in the body and the back of the guitar is removed (peeled away) between the guitar's shoulders. Once the back is seperated from the block the neck becomes 'wobbly'. The back can then be clamped in place with the neck at the correct angle. Ok, so here's how its done. First the binding had to be removed so the back could come off cleanly. I scrape the finish away from the binding with a blade - if I left it on it'd crack and make a mess when the binding came off. Then the binding can be peeled away carefully using the blade.



I don't take it right off, just as far as the shoulders. Guitars are always put together using heat reversable glue which means if you warm them up they come apart. To seperate the back I use heat lamps which gently warm the glue from the back. If it gets too hot the finish can get damaged so its a gentle slow process. When I feel its warm enough I start pushing a spatula into the joint to ease it apart. Push too hard and the wood can split - too soft and nothing happens. In this pic the green tape is holding the binding out of the way. A butter knife is just great for this job.


When the back's off its time to get the action right. I put two E-strings on the guitar and a bridge saddle of the ideal height. Then I clamp the guitar from bum to heel. As the clamp tightens the action lowers.
Once its right its simply a case of regluing the back. .

The back will now be overhanging the sides a little so it needs trimming before the binding goes back.


There's no easy way to re-angle a neck but for me this is the easiest.
