We rent most band and orchestra instruments including violins, violas, and cellos for string instruments, as well as flutes, clarinets, trumpets, alto saxophones, tenor saxophones, bell kits, trombones, euphoniums, baritones, and tubas. 

Rentals are monthly. You’ll provide a debit/credit card that will be set up in our secure payment portal for monthly billing for as long as you choose to rent from us. If your card changes, you can update it in our secure portal, call us or come in during normal business hours.

You will be required to fill out a monthly rental contract, and provide a drivers license or state issued ID card to verify the address provided, as well as your identity. This will be uploaded to your secure customer portal where you can view it anytime.

If the address on your ID doesn’t match the address provided, you will be required to provide a postmarked piece of mail from a utility company.

At the time of rental, you will be charged the first months rent,  your card will be charged on that same day every month. If you rent on the 10th, every 10th of the month or within a couple days depending on your banking institution, holidays or day of the week you will see the charge.

Each rental payment includes Rental Fee (this amount accumulates as Equity), taxes & insurance that will cover damage & normal wear & tear that may happen to the instrument, with the exception of negligence or intentional abuse. It does not cover items such as reeds or strings or if you run over your case.

Rentals are month to month, so when you are done renting, simply return the instrument on or before the day your card is charged each month, and the charges will cease. You’ll fill out a Rental Return Form & it will be added to your customer file viewable in your portal.

As you rent from us you build equity to use towards purchase of the same kind of instrument you are renting. If you rent a flute, you can use that Equity towards a Flute.

Some Instruments come in fractional sizes, such as Violins, Violas, Cellos or Tubas. Your child will most likely begin in a smaller option & as they grow move up to the next size. The rental Equity/Rental Credit carries over as they upsize. Then when they reach full size you can use that equity to own your own. 

Equity or your Rental Credit will only accumulate up to the value of the instrument you are renting. If you are renting a $500 violin that is the max amount you can accumulate to use towards the purchase of the same kind of instrument.

You can decide to Purchase the same kind of instrument at anytime & use the Equity Rental Credit you’ve accumulated while you are renting from us as long as your account is in good standing. 

Late fees will be charged for accounts 10 days past due. You can update your billing info anytime in your customer portal to avoid this or give us a call & we will help.

Once you return your instrument you will have 14 days to use that Equity / Rental Credit for purchase of the same type of instrument. This is not available as a Cash back option for you & cannot be used to purchase another type of instrument than what you were renting.
