"Mirage" Korean built copy of a Gibson 335.

The owner of this Mirage Gibson 335 copy asked me to address multiple issues on this

rather badly treated but otherwise good quality semi hollow body guitar.

This is abetter than average Gibson copy. The materials and build quality are exceptional.

The truss rod cover was missing.

The entire guitar had not had a clean for years, it was covered in a thick layer of dust
and DNA.

Though it is not clear in this image the guitar had fallen off its strap and fallen squarely on its
tuneomatic saddle pushing the curvature inwards ruining the string height on the fret board.
I was able to press the saddle back into its original arc of curvature to match that of the finger board.

All the frets were worn unevenly so I gave them a level, crown and polish.
The truss rod still worked so I re set the neck relief. I scraped, cleaned and oiled the finger board
revealing the beauty of the abalone and ivoroid dragon inlay.

I removed all the Bigsby hardware and all the electronics. There was no signal
from the Bridge pick up and the two tone pots were freely rotating with their
respective wiring disconnected. The selector switch was dodgy as well.

I found a suitable wiring diagram on the net and set about retiring this guitar.
Someone had been inside this guitar and had incorrectly wired it to the extent
that only the font pick up actually worked.

This image shows a corner ding with binding and surface delamitation.
It also reveals a crack from the point of impact to the bottom of the F hole
through the surface of the sound board.

I made a template out of cardboard and fitted the switch, pots and output jack
in their relative locations. The wiring was completely desoldered and resoldered
according to the wiring diagram.

All re assembled with a signal from both pick ups. Volume and tone are working perfectly.
The three way selector switch came apart easily, adjusted, lubed and reassembled.
I repaired the damage to the lower bout using super glue to repair the delaminatation and
glued the crack in the sound board. I touched up the damage with black lacquer

I fabricated a new truss rod cover from a piece of black plastic.
I relocated the forward strap button from its original position on the
neck heel  to a point around the lower side of the neck heel.
The guitar will never again fall from its strap and onto the floor.

The owner is extremely pleased with this guitar now

that is back in playable condition.

Lawsuit era, 1973 Aria 9220 Dreadnought acoustic guitar

My client asked me to replace the Gibson style adjustable saddle on this guitar.
It also needed a fret level, crown and polish.

As you can see from this photo the saddle on this Aria 9220 is the Gibson style chromed,
cast brass adjustable unit with a screw at each end for string height adjustment.

I decided to remove the old adjustable saddle which had tilted in its slot.
I set the guitar up with its bass E and treble E strings on my intonation jig attached to the end pin.
and found the original slot to be in the incorrect position for perfect string intonation.

I took and old ebony piano key and cut it to the perfect size to fill the oversized slot.
Once the new saddle slot was accurately located and marked, I routed a 3mm wide slot into the bridge.
I then fabricated a new saddle out of deer antler and retuned the guitar.
The string height and intonation are now ideal

This is a beautiful guitar.
It rivals a Martin D28 for build quality and materials in my opinion.

Martin OM16DBM String action re set

This Martin OM16 DBM came to me in need of a fret dress and string action adjustment.

on closer inspection I noticed that the bridge was beginning to separate from the sound board.

I removed the bridge with the help of some heat and a spatula.

Typical of almost all mass produced guitars I've seen with this bridge problem, the bridge is glued into place with inadequate preparation.  Commonly the gloss finish is found to extend under the bridge by at least 5 mm. This prevents the glue from adequately adhering the ebony bridge to the gloss finish on the soundboard. There is also a noticeable lip created by the film build up against the bare wood under the bridge creating a void so that the bridge does not make perfect contact with the unfinished surface of the sound board 

My solution is to carefully cut around the bridge with a sharp exacto blade into the sound board to create a perfect margin marking the extreme edge of the bridge in its exact location. I then remove the  bridge after which I take a sharp scraper and remove the excess gloss finish to the  cut margin and scrape all traces of the old adhesive away as well.

This leaves me with a slight cavity into which the bridge sits perfectly. I always prep the underside of a wooden bridge with a scraper, then sandpaper then with acetone to remove all traces of resin from the wood which might otherwise prevent a perfect glue bond. I then scratch the under surface of the bridge with a razor saw to etch the surface prior to applying Tightbond glue. Replacement of the bridge requires 3 deep throat C clamps with wooden cauls above and below. I apply as much pressure as possible when clamping.

While I was at it I levelled, crowned and polished the frets. I also re set the neck relief, the first adjustment of the truss rod since the guitar was new in 1999.

I re strung the guitar and found the string height to be too high by 1 mm per bass E string and treble E string. I shaved 2 mm off the bottom of the tusk saddle which restored the string height back to ideal for my client, (2mm at the 12th fret on the low E and 1.6 mm on the high E string)

There was also a compression ding at the margin of the lower bout so I decided to apply some spot heat with my soldering iron through multiple layers of a wet cotton cloth. This has the effect of swelling the wood where it is compressed. With multiple applications the ding gradually disappeared. I then refinished the damaged lacquer with multiple coats of aircraft dope using an airbrush.

the repair is virtually invisible.

3 deep throat clamps apply pressure to the bridge until the glue has cured (a minimum of 12 hours)
