• 3-channel bass amp simulator featuring an all analog signal path
• Inject some warmth and bite into your tone courtesy of a 12AX7 preamp tube running at high voltage
• DRY/WET to adjust the balance between the dry BASS IN signal and the MODERN DRIVE channel signal
• Expertly engineered Analog Cab Sim for seamless DI whether it’s in the studio or on stage
• 4-Cable mode, FX Loop and MIDI In/Out for effortless integration into existing setups
• Robust, made-to-move design that’s perfectly sized for pedalboards and fly-rigs
• Includes a lifetime license to Wall of Sound and GENOME, the final word in digital app- and plugin-based tone-shaping for the forward-thinking player (VST/AU/AAX/Standalone)
• Includes the ReVolt: Series-B DynIR Cabinet Collection (valued at 100€/$) featuring 10 exquisite DynIR captures inspired by leading guitar amplifier brands

Each of the channels can be activated by pressing the CLEAN, DIRT, and DRIVE footswitches. The LED above the footswitch will light up when the channel is active:

• Green for the CLASSIC CLEAN channel
• Orange for the VINTAGE DIRT channel
• Blue for the MODERN DRIVE channel

Simultaneously pressing the CLEAN and the CRUNCH switches will bypass ReVolt.

This switch determines the behavior of ReVolt’s effects loop alongside its bypass behavior. See the section Supercharge your amp with the 4 cable method for comprehensive setup guidelines for this feature.

Enables the analog cabinet simulation applied to the BALANCED and Headphone outputs of ReVolt by engaging the CAB SIM switch (I Position). For ReVolt Bass, the analog simulation is inspired by an Ampeg SVT-810E cabine

Connect your music player here and control the playback level via the source’s controls. This input is stereo.

The headphone output is a 1/8” TRS jack socket. This output is calibrated for headphones rated up to 100Ω. ReVolt’s signal is mono - the AUX IN can only be heard in stereo via headphones. The cabinet simulation applied with the CAB SIM switch can also be heard through the headphone output.

Connect your instrument here. The input is a ¼” TS (unbalanced) jack socket.

Use this unbalanced output to connect to effects pedals or to an amp’s Instrument input when the 4-CABLE METHOD switch (E) is activated. The SEND output is a ¼” TS jack socket.

When the 4-CABLE METHOD switch is activated, and when ReVolt is bypassed (no active channel), the SEND outputs the dry/unaffected guitar signal to the connected amplifier/device.

Use this unbalanced input to connect the output of any external effects to ReVolt, or connect the amp’s effects loop SEND to this input when the 4-CABLE METHOD switch (E) is activated. The RETURN input is a ¼” TS jack socket panel-mount connector.

When using effects pedals (delay, reverb, etc.), ensure the 4-CABLE METHOD is set to O. The processed signal of the effects will be heard when a channel is active on ReVolt.

This unbalanced output (¼” TS jack) sends the dry signal of ReVolt’s channels - the CAB SIM is never applied to this output.

The MIDI In/Out sockets are ⅛” TRS jack panel-mount connectors. One TRS 1/4” jack to MIDI type A adapter cable is provided with ReVolt.

By default, ReVolt sends and receives Program Change (PC) messages from 1 to 7 . Edit all MIDI messages through ReVolt’s dedicated MIDI Setup menus (see the MIDI SETUP section of the manual for more details)

Use this balanced output to connect directly to your audio interface, monitors or mixing desk. Apply speaker simulation to this output with the Cab Sim Switch (F). The GND/LIFT switch eliminates unwanted hum caused by ground loops when activated.

Connect the provided power supply here. ReVolt needs 12V DC, 600mA and a center negative polarity to work.

Use ReVolt to go-direct to mixing desks audio interfaces when on stage or recording respectively.

Using the BALANCED OUT with the CAB SIM engaged, send your complete guitar tone out of ReVolt. Further refine your tone by adding effects in the FX Loop of ReVolt.

You can also use a C.A.B. M+ connected to either the effects loop or OUT output to add our class-leading DynIR cabinet emulation to your rig.

If your amp is equipped with an effects loop, add ReVolt’s 3 channels to your amplifier’s channel specification. Engage the 4-CABLE METHOD on ReVolt, and combine ReVolt’s effects loop with the amp’s using the following connectivity guidelines.

1. Connect your instrument/pedalboard to ReVolt’s IN
2. Connect ReVolt’s SEND to the amp’s input
3. Connect the amp’s effects loop send to the ReVolt’s RETURN
4. Connect ReVolt’s OUT to the amp’s effects loop return

When ReVolt is bypassed, the dry bass signal passes through the amp’s input and all the amp’s features/tone shaping are unaltered by ReVolt’s all-analog processing. When a channel is activated on ReVolt, the signal passes through the instantiated ReVolt preamp and companion tone stack, feeding only the amplifier’s power amp.

Connect the OUT output to your audio interface’s instrument input and combine ReVolt’s channels with Wall of Sound for enhanced cabinet simulation and additional post-processing effects.

Alternatively, disengage the CAB SIM, and use the BALANCED OUT with your audio interface’s mic preamp to record / process your signal with Wall of Sound.
