The Revv Generator G50 MK3 is a professional instrument designed for electric guitar amplification, offering a versatile and powerful sound experience. This owner's manual provides comprehensive details on its functions, usage, and maintenance, ensuring users can maximize its potential while adhering to safety guidelines.

Function Description

The Generator G50 MK3 is a tube amplifier featuring three distinct channels: Clean (Channel One), Crunch (Channel Two), and High Gain (Channel Three). Each channel offers a wide range of tonal possibilities, controlled by passive treble, middle, and bass knobs. Small adjustments to these controls can lead to significant tonal changes.

Channel One (Clean): This channel provides a clean tone and includes a "Bright" function for a brighter or warmer sound, useful for various gain pedals. The "Wide" function, activated by pressing the channel button, boosts all frequencies for a bolder sound.
Channel Two (Crunch): This channel offers tones from nearly clean to significant gain. Its "Bright" function allows for tailoring the high-end response, while the "Crunch Gain" knob controls the amount of gain. The "Crunch Drive" mode, cycled by pressing the channel button, alters gain and frequency intensity.
Channel Three (High Gain): Designed for aggressive tones, this channel features gain, treble, mid, bass, and level controls with a wide range of operation. It includes three "Aggression" levels (least saturation, tight saturation, and highest/fattest saturation) that interact with the gain knob to produce sounds from broken-up rock to metal rhythms and leads. "Bright," "Cut," and "Fat" controls further extend high, mid, and low frequencies, enhancing presence and bass response.

The amplifier is equipped with two MIDI and footswitchable/programmable master volume controls, which also function as FX loop return controls. These can be toggled via the footswitch or a MIDI device. Global controls for "Depth" and "Presence" affect all channels, allowing for powerful brightening, cut, and low-end enhancement.

A built-in reverb effect can be toggled on/off for each channel using the reverb switch, with its intensity controlled by a dedicated knob on the rear panel. The amplifier also features a high-quality noise gate, activated by the gate switch, with a threshold control on the rear panel to manage signal levels and prevent unwanted noise.

The "Store" switch is crucial for saving various settings, including MIDI configurations and channel presets.

For silent practice or direct recording, the G50 MK3 incorporates Two Notes Technology. A headphone jack provides stereo output with selected virtual cabinet I.R. settings, allowing for great tone without a speaker. The headphone/XLR level control adjusts the output level for both headphones and the stereo XLR outputs on the rear panel. A 6-position selector switch allows users to cycle through the first six virtual cabinet presets saved to the amplifier, which can be customized using the Two Notes Remote software. Bluetooth connectivity enables on-the-fly adjustments via the Two Notes app.

Usage Features

The G50 MK3 offers extensive connectivity and control options:

Front Panel: Input jack for instrument cable, channel selection buttons with corresponding LEDs, gain and level controls for each channel, master volume controls, Depth and Presence knobs, and switches for Reverb, Gate, Store, Virtual Cabinet, Standby, and Power.
Back Panel: Main power connection, fuse holders (Main, HT, and Power Tube Fault Fuses), Bias Test Points for power tube biasing, XLR Output and Ground Lift for direct recording, USB connector for Two Notes Remote software, Reverb Level and Gate Threshold controls, Wattage Switch (10W/50W), Internal Load Switch, FX Loop Send and Return jacks, Cabinet Lighting jack, Footswitch Connection, MIDI IN/THRU connections, and Impedance & Speaker Jacks (4, 8, 16 ohms).

The amplifier supports MIDI control for various functions, including channel selection, drive levels, aggression levels, bright/cut/fat functions, FX loop, master volume, reverb, noise gate, and Two Notes Embedded functions. It can store up to 128 program settings and accepts Continuous Controller (CC) commands. OMNI mode allows the amplifier to respond to commands on any MIDI channel, while disabling it allows for designated channel control.

The Revv footswitch can operate in "Control Mode" for direct function control (channels, FX loop, master volumes) or "Preset Mode" for recalling saved combinations of settings with a single button press. Each button on the footswitch can save a preset, including digital cabs.

Maintenance Features

The manual emphasizes several maintenance aspects:

Safety: Users are instructed to read and follow all safety instructions, including proper placement (4-6 inches of space for heat dissipation), avoiding damp environments, keeping liquids away, and ensuring the top heat vent is unobstructed. It warns against high temperatures and stresses the importance of connecting to a compatible AC power supply and using an undamaged power cord. Proper grounding is essential.
Tube Replacement and Bias: Instructions are provided for safely replacing power and preamp tubes. Power tubes require biasing, and the manual details the process using a voltmeter and bias test points on the rear panel. It includes a bias chart with recommended and safe ranges for different tube types (KT88, EL34, 6L6GC). Preamp tubes do not need biasing but can become faulty.
Fuse Replacement: The amplifier is protected by Main, HT, and Power Tube Fault fuses. Users are instructed to replace blown fuses with matching types and ratings, always with the power off and the amplifier unplugged.
Troubleshooting: The manual offers troubleshooting tips for Bluetooth connection issues with the Two Notes Remote app, advising users to unpair the Torpedo from their phone's Bluetooth menu and activate location services if necessary.
Factory Reset: A procedure is outlined to clear the amplifier's memory, restoring all settings to factory defaults, including MIDI channel, OMNI mode, FX loop state, and a full memory clear.
Footswitch Reset: Instructions are provided to clear the footswitch's memory, returning all 6 banks to factory defaults.

The G50 MK3 is designed for durability, with components like input jacks, connectors, and control switches warrantied for one year, and the amplifier itself for five years against manufacturing defects. Tubes and fuses have a 90-day warranty. The manual stresses that all service should be done by qualified personnel only, as there are no user-serviceable parts inside.
