Ganymede is an OP07 based distortion circuit. It can go from light overdrive to distortion to full on thick saturation. It has true bypass and a very quiet LED switching circuit to tame the ON/OFF pop.
Current draw: Max 1.8mA at 9V
Impedance: 1.1MΩ input impedance, 1kΩ output impedance
Power: This pedal can be powered by a 9V battery or 9V to 18V 2.1mm center negative DC power source. Unplug the IN jack to preserve battery. When a DC plug is inserted into the DC jack the battery is disconnected from the circuit.
Size, weight: (LxWxH) 11.3 x 7.1 x 5cm, 230g without battery
Operation: Volume: raise or lower the output volume of pedal. Dist: Raise or lower the level of gain/distortion. Lower settings produce overdriven tones while higher settings can get very compressed and fuzzy. Filter: low pass filter to cut top end.
The chip at the heart of Ganymede is the OP07. This chip gives the pedal it's great qualities- it's very slow compared to other op amps, and colors the tone in a good way. It also attenuates high frequencies that can be harsh in very high gain circuits and also means that it never gets fizzy. Because the chip attenuates high frequencies at higher gain, the Filter control can be used to retain highs.
