I offer a repair service, specialized adjustment for guitar and bass, restoration for violin, viola, cello and upright bass and restoration for vintage instruments for collectors


For the comfort of playing, a guitar must be well set. Given to our harsh climate, it’s highly recommended by all manufacturers to make a complete adjustment to your instrument at least twice a year. It’s advisable to have a controlled environment about 71 degrees and 45% humidity to avoid deformation or fracture of the instrument.

Our design

Each guitar is handcrafted from first quality tone wood, with a minimum of five years of air drying. The body features deep dish carving and the neck joint is hand carved for easy upper register access, with a true mortise and Tenon neck joint for strength and tone. All these elements are combined to provide superior tonal quality, increase sustain and precision pitch adjustment. The Demers guitars are available with a wide range of options to create that special dream guitar you have always wanted.

“This beautiful V guitar made by Jef Demers it’s by far the best V style guitar have ever played!”
