Information about instument repair  Sales information about Deering Banjos  Other musical instruments for sale  Useful links to related musical websites

The main focus here in my shop is the repair of fretted stringed instruments. Ailing acoustic and electric guitars, electric and acoustic bass guitars, banjos, mandolins - all are welcome here. However, due to an overwhelming demand for my work on fretted instruments, I am no longer able to take in any work on bowed, violin-family instruments or other stringed instruments such as autoharps and dulcimers

Here is a partial list of routine services I provide every day:

  • Super-accurate action adjustments with measurement tolerances to 1/1000th of an inch.
  • Clean, careful refretting.
  • Exacting truss rod adjustments and meticulous fret honing (leveling).
  • Fussy, detailed intonation adjustments.
  • All kinds of structural repairs - cracks, warps, broken braces, broken necks, etc.
  • Pickup installation in acoustic and electric guitars, including custom routing of bodies or bridges, custom pickguards and custom wiring, plus repairs to guitar electronics (I don't work on amps).
  • Hand-carved saddles and nuts made of genuine bone, ebony, brass, graphite, synthetics, etc.
  • Acoustic guitar bridge repair, reglue, or replacement.
  • Installation of all sorts of replacement parts, factory original, generic or custom: tuning machines, tailpieces, pots, switches, hardware, banjo heads, custom-shaped pickguards made from a variety of materials…. you name it. I either already have it in stock, can order it in, or can make it for you!

My workshop and instrument storage area are constantly monitored for temperature and humidity levels, so instruments are always exposed to the best of conditions when they are in my shop.

My estimates are free. I evaluate each instrument individually so I don't publish prices, but I believe you will find my rates to be competitive with other experienced professionals. I'm really, really fussy about accuracy so I don't give estimates until I've seen the instrument in person. Got a special problem? Just let me know. I'll do my very best to get it corrected.

You are welcome to SHIP instruments to me for repair estimates (I prefer UPS, and fully-insured). If you do this, please pack and pad your instrument really well to avoid damage during shipment. I will not be responsible for instruments that are damaged in shipmend due to your poor packaging. You must pay the shipping and handling both ways - repaired or not. You must also call or email me in advance for authorization (instruments sent without prior authorization will be refused).
