    New Top-Brand Gear From An Authorized US Dealer

    You get top-brand gear, new from the factory, from an authorized US dealer. Our products are shipped from the vendor to our warehouse, and then from the warehouse to you. There is no detour through a retail store, where the boxes are opened, the products put on display, and then sold as leftovers. When you shop online, make sure you are comparing new gear from authorized US dealers. 

    Special Opportunities: When It's Not New, We Tell You

    We occasionally have opportunities to buy B-stock merchandise to offer at special discounts. We also sometimes get returns in less than perfect condition. Sometimes we will offer these products to you - but we always identify it clearly as such using the classifications below. So unless it says otherwise, it's new from the factory.

    Important Guarantee: Your 100% Satisfaction

    Regardless of the condition described on our site, what you should remember is that if you are not 100% satisfied with your purchase you may return it (though exceptions apply for some products). Of course, if you know you will only be happy if a product is 100% cosmetically perfect, then you shouldn't order B-Stock or Blemished merchandise - it's just not a good gamble. And if you will only be happy if a product has never been touched by another human, well then the Resealed products aren't a good choice for you. But if you are looking for even more impressive values than our already-low prices, then these options will be very attractive when available.

    These are our best descriptions of the quality and condition of this merchandise. Because of the highly efficient, automated nature of our warehouse, and the high volume of products we stock and ship, there is no way for us to provide any additional detail on the condition of any individual item. Just remember our 100% satisfaction guarantee!

    Warehouse Resealed

    A warehouse resealed product is usually a customer return. These products are not in absolutely new condition, but will ship with everything the brand new product would ship with including manuals* and the full factory warranty*. These products are still covered by our 30-day satisfaction guarantee, so they're a great deal! 

    Blemished

    This is typically a customer return with minor cosmetic imperfections, such as superficial scratches or scuffs on the finish. This inventory includes all parts, components, manuals (hard copy or downloadable) and the full factory warranty*.

These products are still covered by our 30-day satisfaction guarantee, so they're a great deal! 

    Scratch and Dent

    This is typically a customer return that shows general wear and tear, along with dents and scratches. This inventory includes all parts, components, manuals (hard copy or downloadable) and the full factory warranty*. It has been tested to manufacturer's specifications and is guaranteed to work perfectly, but will show signs of use. It may be less attractive than Blemished inventory, but it's priced even lower! These products are still covered by our 30-day satisfaction guarantee, so they're a great deal! 

    Factory Resealed

    A factory resealed product is purchased directly from its manufacturer, who may have refurbished the product or used it for training and demonstration purposes. These products are not in absolutely new condition, but will ship with everything the brand new product would ship with including manuals (physical copy or downloadable) and the full factory warranty*. These products are still covered by our 30-day satisfaction guarantee, so they're a great deal! 

    B-Stock

    A B-stock product is purchased directly from its manufacturer, who may have refurbished the product or used it for training and demonstration purposes. These products may be cosmetically blemished, but will ship with everything the brand new product would ship with including manuals (physical copy or downloadable) and the full factory warranty*. These products are still covered by our 30-day satisfaction guarantee, so they're a great deal! 


    *Warranty coverage for non-new gear varies by manufacturer. To see if the non-new product you’re interested in has warranty coverage, click the "What is Blemished/Warehouse Resealed/etc." text link near the price on the product page.

    Product Description


    The OB-6 is a once-in-a-lifetime collaboration between the two most influential designers in poly synth history, Dave Smith and Tom Oberheim. The OB-6 takes the classic bold Tom Oberheim sound
    - with its true voltage-controlled oscillators, 2-pole filter, and amplifiers
    - and adds modern enhancements such as studio-quality effects, a polyphonic step sequencer, an arpeggiator, and more. No other modern analog poly synth can boast such a pedigree or such a massive, in-your-face sonic signature.

    Vintage SEM Tone

    The OB-6 sound engine is inspired by Tom's original SEM, the core of his acclaimed 4-voice and 8
    - voice synthesizers. It features two discrete voltage-controlled oscillators (plus sub-oscillator) per voice with continuously variable waveshapes (sawtooth and variable-width pulse, plus a triangle wave on oscillator 2). The classic Oberheim-inspired 2-pole, state-variable, resonant filter provides low-pass, high-pass, band-pass, and notch functionality. Voltage-controlled amplifiers complete the all-analog signal path.

    Dual Effects

    The dual effects section provides studio-quality reverbs, delays (standard and BBD), chorus, flangers, and faithful recreations of Tom's original phase shifter and ring modulator. While the effects themselves are digital, with 24-bit, 48 kHz resolution, a true bypass maintains a full analog signal path.

    X-Mod and Poly Step Sequencing

    Also present is X-Mod, which expands the tonal palette and makes it easy to create dramatic and unconventional sounds. Modulation sources are filter envelope and oscillator 2, both with bi-polar control. Destinations include oscillator 1 frequency, oscillator 1 shape, oscillator 1 pulse width, filter cutoff, and filter mode. The polyphonic step sequencer allows up to 64 steps and up to 6 notes per step. You can create sequences polyphonically, with rests, and sync to an external MIDI clock. The full-featured arpeggiator can be synced to external MIDI clock as well. Unison mode features configurable voice count (1-6 voices), chord memory, and key modes.

    Easy to Program

    The knob-per-function front panel puts virtually all OB-6 functions at your fingertips. Included are 500 permanent factory programs and 500 rewritable user programs. Turning on the Manual button enables live panel mode, in which the sound of the OB-6 switches to its current front panel settings. In this state, what you see is what you hear.

    Easy to Play

    This analog powerhouse is packed into a four-octave, semi-weighted keyboard with velocity and channel aftertouch, making it perfect for stage or studio.
