About Item Conditions


Questions?
Call or text us at 301-946-8808.

New: The item is brand new as received from the manufacturer with a full manufacturer warranty. Instruments such as guitars, snare drums, drum kits, brass and woodwind instruments may be opened for photography and quality control inspection and may not be in a factory sealed box.

Mint or Open Box: The item may have been opened and tested but has been repackaged. The original packaging may have superficial issues but the item itself and any originally included accessories are in perfect, like new condition.

Display Model: These items are so cool that we put them on display in our legendary shop. The condition is brand new as received from the manufacturer with manufacturer warranty. Rest assured, these items undergo a very careful inspection before shipping.

Demo: These items have been on our sales floor for demo purposes and will likely show signs of use. The original packaging may no longer be included, but you can be assured that you are receiving an awesome item and an awesome price.

Used: The item is used. These item may have varying degrees of wear. Please read the description for information about the condition of the item. Used items do not carry a warranty.

B or C Stock: Factory refurbished. These items were purchased from the manufacturer in a refurbished condition. They will show some cosmetic issues, but nothing that would impact performance. Being that these are sealed from the manufacturer, we generally do not open these to photograph the cosmetic issues. They are guaranteed to work and may have a limited warranty or you may purchase an extended warranty in some cases. Please see the listing description for item specific information.


Get Classic Analog Waveforms With The Make Noise DPO Dual Voltage Controlled Oscillator Module

A dual Voltage Controlled Oscillator designed for generating complex waveforms. Expanding on the classic arrangement of Primary and Modulator Oscillators, the DPO has both of the VCOs operable as complex signal sources. It is in essence a Dual Primary Oscillator.


  • Vintage voiced, all analog
  • Triangle Core with Sine, Saw, Spike and Square wave shapes
  • Dedicated FM and Mod buses
  • Modulation source signals are internally routed with associated destination CV attenuators setting final depths
  • Mod Bus has added capability of using external source (patched at EXT. SouRCe input) in place of VCO 1 Sine
  • Bi-Directional Dynamic FM Bus allows for circular FM
  • VCO A features Hard Sync circuit which combined Dynamic FM yields complex sounds
  • VCO A operates as LFO, perfect for slow morphing of VCO B timbres
  • VCO B features complex timbral control through the use of a 3 parameter waveform shaping and Dynamic FM
  • Utilizes Vactrols
  • Pairs well with the Echophon

  • 1V/Octave control Input: uni-polar pitch control, optimal range +/-5V
  • Expo Input: Exponential frequency control input. normalled to FM Bus. bi-polar, 10V range
  • External Lock: allows VCO B to phase locked to hard edged signal (square, pulse or Sawtooth) from other VCOs.

VCO Interaction:

  • Beat Frequency LED: visual indication of Phase difference between VCOs A and B.
  • Follow CV Input: unipolar control input. Range 0V to 5V.
  • Follow Attenuator: determines how well VCOA Follows VCO B. With nothing patched to Follow CV Input works as standard panel control. With Signal Patched to Follow CV Input, works as an attenuator for that signal.
  • FM Bus Index: unipolar panel control that sets the index (depth) of the FM.
  • FM Bus Index LED: indicates the currently programmed FM Index Value.
  • FM Bus Index CV Attenuverter: bipolar attenuator for FM Bus Index CV Input.
  • FM Bus Index CV Input: bipolar control signal input. Range +/- 4V

VCO B Timbre Controls and Mod Bus:

  • Shape Panel Control: unipolar control that determines the shape of the waveform feeding the Folding circuit. Morphs from Sine to Spike to Glitched Triangle
  • Shape CV Attenuator: unipolar attenuator for Shape CV Input.
  • Shape CV Input: unipolar control signal input. Normalled into the Mod Bus. Range 0V to +5V.
