Welcome to our website! As we have the ability to list over one million items on our website (our selection changes all of the time), it is not feasible for a company our size to record and playback the descriptions on every item on our website. However, if you have a disability we are here to help you. Please call our disability services phone line at 918-495-0586 during regular business hours and one of our kind and friendly personal shoppers will help you navigate through our website, help conduct advanced searches, help you choose the item you are looking for with the specifications you are seeking, read you the specifications of any item and consult with you about the products themselves. There is no charge for the help of this personal shopper for anyone with a disability. Finally, your personal shopper will explain our Privacy Policy and Terms of Service, and help you place an order if you so desire.

Develop unique sounds

The second musical instrument in our TORAIZ range, the AS-1 is a monophonic analog synthesizer that brings new creative possibilities to the studio and the stage. Its intuitive controls include parameter knobs that let you make both subtle and dramatic changes to the tone of your music to create your own personalised sound. Plus you can use the touchpad-style keyboard and slider to manipulate sounds during performances.

The TORAIZ AS-1 is driven by a fully programmable, true analogue synthesis engine based on the discrete analogue circuitry in Dave Smith Instruments' Prophet-6 synthesizer. It also inherits 7 on-board effects from the Prophet-6 synth as well as a brand new digital distortion.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy, and expensive and you probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.
