The Double Bass Workshop


"I’ve just received your nice clamps.  I am really impressed by their design and quality.  Great strong lightweight clamps with nice conception details.  You can surely add me to your website list of proud and happy users of Tom Barrett Bass Clamps!"

Richard Benoit, Luthier  - 

"Really pleased with your clamps. Wish I had had them 40 years ago! Superbly engineered to a very practical and ingenious design."
Timothy Batchelar Stringed Instruments,  Leicester UK

"I received the clamps this morning and very nice they are too. I really like the facility to lock the clamping pads square or otherwise, a very nice touch! Thank you for your  excellent  service."
Martyn Bailey

"The clamps arrived yesterday and I have already put them to use. They are the perfect size and weight, and could only be designed by someone who understands basses and bass repair. Excellent job!!"
Kindest Regards,
Al Genduso, Alberti's Violins
