Marvel Drive

The Marvel Drive by Ramble FX is a versatile overdrive effects pedal designed to deliver the classic rock tones associated with vintage plexi amplifiers. The pedal features unique "blended volume" controls that simulate a plexi amp with its inputs patched together, resulting in two differently voiced gain controls that can be mixed together.

Key Technical Specifications:
- Circuit: 100% JFET based, with no clipping diodes or op-amps
- Input Impedance: 700kohm
- Output Impedance: ~15kohm
- Power Requirement: 9 volts DC adapter or battery
- Current Draw: 22mA ON, 14mA OFF
- Dimensions: Length 4.8", Width 2.6", Height 2.4"
- Weight: 0.8 pounds
- Bypass: Relay-based true bypass
- Additional Features: Low-noise metal film resistors, charge pump voltage doubler, Neutrik jacks, Alpha potentiometers, plexi style faceplate, Marshall knobs

The Marvel Drive is equipped with an innovative dual voltage switch, allowing it to operate at 9V or 18V, providing a boost in volume and a sharper attack when set to 18V. The pedal's circuit is entirely JFET-based, replicating the touch-sensitive and dynamic response of a plexi amplifier.

Overall, the Marvel Drive is designed to recreate the distinctive crunch sound of vintage 4-input Marshall amps, offering guitarists a versatile tool for achieving classic rock tones.
