QBC's COVID-19 response:
- The health and safety of our staff and clients is paramount. We will continue on an appointment-only basis, with specific protocols, until COVID-19 is contained. Phones are unattended; please email. 
- Mask required for entry.
- For strings, sheet music, accessories, and now many of our instruments, shop from our full-line web store, QuantumBassMarket.com
- Staff has work-from-home hours and is available via email. Don't hesitate to contact us!
- Please correspond before sending us anything, so we can arrange to retrieve it from the post office/air cargo
- We are currently not taking in new repair work, due to ginormous backlog.
- We have NOT increased our prices ("COVID-19 surcharge"), which would be not only undignified, but detrimental to our future relationships with our clients who have lost all or most of their work.

​New inventory additions!

- The first ever Wultur 5/8 basses have arrived at QBC - be the first to own this beautifully made model!
- Excellent values in the $20k - $30k range: well set up, developed tone, well-established makers that will hold their value.
​- New "Oberon" model laminated 5/8!

just have your friend give us your name upon renting or purchasing, and we'll write you a $25 store credit! It is really that simple. Who'll be the first to get an entire instrument at no charge?

OUR MISSION: To foster the lifetime growth of bassists and all string players through access to highest-quality equipment and education.
