Authorized dealer for all new products we sell
Dave Smith founded Sequential Circuits in 1974, and its Prophet-5, released in 1978, was the first fully programmable polyphonic synthesizer. Today Sequential builds analog poly synths, including the OB-6 made with Tom Oberheim. Synths are hands-on instruments, so come and play the Sequentials in our Peterborough store.

I had an excellent experience with Maars Music. Markus went above and beyond to help me update the firmware on my DJ mixer. I had spent quite a while trying to figure it out but the instruction's weren't much help. Markus knew exactly what to do and had it sorted out quickly.
It’s refreshing to deal with someone who has that level of knowledge and is willing to take the time to help. The customer service was outstanding and it’s clear they genuinely care about their customers.
If you’re looking for knowledgeable staff and great service, I highly recommend Maars Music. Thanks again, Markus!
bought an amplifier recently, I'm located in Vancouver area. Seamless purchase via website. Edwin contacted me immediately to advise that it wasn't available due to a stock error, but offered me a reasonable option or to wait for new stock. I chose to wait, but had the amp in my hands within 2 weeks along with 2 sets of complimentary guitar strings. Edwin's customer service and communication were outstanding. He took ownership and kept me informed throughout. Highly recommend this business!
I have taken two devices into Maar's music to be serviced by there certified Apple Technicians and both times they have done an amazing job. One was a warranty repair and the other was an out of warranty battery replacement. Super impressed with their speed and service. Will definitely be back. Very convenient to not have to drive all the way to an Apple Store.
