Hi John,

I just had to say, thank you for your efforts and the friendly delivery on todays course.
Although I have been playing harmonicas for many years, I have only ever scratched the surface of the inner workings.
Your course has made me more confident to know what to do and meeting new friends as well!
Kind regards
Mick

Due to the growing demand for repairing harmonicas, I have put together a one day repair masterclass. This will be a full on day working here in my workshop. It will be very "hands on". Im going to be demonstrating and talking about repair techniques first, BUT then you will be practicing what I preach .  I have full workshop facilities here and you will be working under my supervision. I have purposely kept the class to a very low number so that each and every participant will get the opportunity take a harmonica apart and fix it. The day will cover, but not be limited to : 

  • Purchasing a harmonica online and what to look for. 
  • Inspection of parts while assembled 
  • Disassembly
  • Cleaning
  • Slider and Mouthpiece overhauling  
  • Windsaver inspection and replacement
  • Comb  repair / exchanges
  • Reedplate conversions, leveling 
  • Reed replacement 
  • Reed Gapping and Shaping
  • Tuning 
  • Assembly & Tryout.

As the Certified Hohner Repair Technician for the UK this course is a must for anyone looking to maintain their own harmonica.  This is the first workshop of its kind in the UK where you will actually work on your harp. Free Tea and Coffee will be provided all day. You will need to bring a pack lunch. The course will run from 10am to 3pm.  Due to the limited space and tools I have available, I want each participant to get really involved and therefore I will limit the class to  8 places. If there is greater demand and the dates are not suitable, please get in touch so that I may consider running more classes.  

You will need to bring your own harmonicas if you would like to work on them, but if you dont fancy practicing on your harp then I can supply the harps for the day... . 

The cost is only £65 for the full day.   £5 discount if you are a member of the NHL.  ( Free Tea and Coffee and biscuits  will be provided.).
