Hi all,

I am a newer guitar tech and after dozens of repairs this particular Simon & Patrick Luthier Cedar top SP6 acoustic dreadnought from the 90-ies with a bolt-on maple neck has been an incredible challenge.

It came with a maxed out and stuck truss rod with a considerable up bow in the neck, extremely low saddle with barely any string break angle, so it needed a neck reset. Later on I figured out that it also has a pretty drastic neck twist with treble side dip at headstock and bass side raised at headstock, and the opposite situation at neck/body joint.

I managed to free up the truss rod without breaking it, did a neck reset and then levelled the frets using the understring StewMac FretBar. However the result was much string buzz starting pretty much from fretting at 2-03 fret and up.

As a result, I ended up pulling the frets and levelling the fretboard using a 24" stewmac sanding beam. Upon which I did a full refret using EVO gold fretwire with fish glue, my arbor press and clamping frets overnight.

before levelling the new frets, I ordered and received the Elerwine Neck Jog from StewMac. I set the guitar up in the jig per manual and the YouTube, and did the fret levelling job.

However, I am now still stuck with a similar buzz especially within 2-5 frets on all strings except B and High E. A that's at 6/64 and 5/64 action with 0.007" relief!

I would honestly welcome any constructive criticism, ideas and diagnoses of my errors and mistakes, since this has long become a money losing operation and the client is quite upset with the delay! Thanks, everyone, I appreciate the opportunity to join this community!

Kind regards,
Ron
