This section lists the key specifications of the software that is used to interact with the guitar.
‘Aestheticodes’ app available from iTunes and Google Play
Where the various aestheticodes are located on the guitar:
Code Location on the guitar
1:1:1:1:2 Headstock logo (inlay)
1:1:3:3:4 Soundboard repeated three times on the upper and lower bouts (inlay and sound hole)
1:1:2:4:4 Soundboard under the strings (inlay and sound hole)
1:1:1:4:5 Back of the guitar (inlay)
1:1:2:3:5 Removable soundhole in the top side (Iinlay and sound hole)
1:1:5:6:6 In the cutaway ‘nook’ underneath where the neck joins the body (inlay)
1:1:1:1:1 Fret marker ay the 12th fret (inlay)
Aestheticode config file
The mapping of these various aesthetocdes to the specific actions carried out by the app when they are scanned is specified in the Aesthticodes configuration file. The following is the current version of the Carolan configuration file that was updated on November 1st 2014:
“modes”: [“detect”, “outline”, “threshold”],
The following provide information about how to maintain the guitar.
Accessing the inside (including the battery pack for the pickup)
Remove the top sound hole (held in by magnets).
The battery pack is located in a fabric holder that is velcroed just inside this sound hold towards the lower bout of the guitar.
Accessing the truss rod
To change the software configuration contact either Kevin Glover (who manages the Aestheticodes software), Steve benford or Adrian Hazzard by email at first firstname.lastname@example.org. You can edit the config file and send them a new version or request them to make specific edits.

Adrian Lucas – Lowering the action – 2014
Adrian Lucas of the Newark Guitar Workshop lowered the actions and straightened the alignment of the strings. This involved thinning out the bridge and also plugging and subsequently redrilling the holes for the bridge pins. Work completed 15th October 2014.
Colin Keefe – Neck Shim 2019
Carolan’s fingerboard was removed. This revealed that the headstock and veneer were both lifting …
The fingerboard was glued securely at the body end, so heat was applied …
… and a palette knife used to loosen it …
The fingerboard was then removed …
Since the veneer was lifting, it was removed, cleaned up and re-glued …
A rosewood veneer shim was glued to the underside of the fingerboard and tapered down to nut end.
This raises the angle of the fingerboard in relation to the body so that a line extending out from the fingerboard (including the frets) will clear the bridge with room to fit a normal height saddle. It’s difficult to get a clear photo of the tapered shim, but it is basically like this …
The neck was then sanded flat to remove any old glue and the shimmed fingerboard was glued back.
Once glued, a long ruler was laid along the frets to measure where the angle of the fingerboard meets the bridge. This was found to be very slightly lower than the bridge, so the bridge was planed down until a ruler laid from the bridge along the fingerboard was flat to the frets. At this point the frets were also stoned level and re-crowned.
It is impossible to do this type of repair without some minor damage to the finish, particularly around where things have been re-glued. Therefore the back, sides, fingerboard and bridge were masked off, the existing finish to the neck and top of the guitar flattened off with 400 grit paper and finishing coats of lacquer sprayed, flattening off between each coat.
The original saddle was broken so a new one was made from bone. The truss rod was adjusted to give the correct amount of neck relief and the new saddle cut to give an acceptable playing action. The new saddle was slightly shorter than would be ideal but the depth of the saddle slot could not be easily be increased to allow a taller and therefore stronger one to be fitted due to the way that the slot had been originally routed (wider at one end). A thin reinforcing maple shim was therefore glued to the bottom of the new saddle for added strength.
Finally, the string slots at the nut were re-cut.
The action (string height above frets) after the repair is now at 2.5mm at the 12th fret on the bass side and just under 2mm on the treble, which is around half of what it was before the repair – the guitar is now playable again.
If over time the top continues to pull up under string tension the action will increase. If it becomes unplayable again the next course of action could be to make a new, thinner bridge.
Colin also removed the old B-band pick-up and supplied and fitted a new Fishman Matrix pick-up. This included routing the saddle slot to suit and making new saddle in water buffalo horn followed by a set-up.
