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:
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.
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.

The setup menu is entered by holding down footswitch A and providing power to the device. When the setup menu is entered, the “tube window” will show the “first page” color.
The Page order is as follows:
The MIDI monitor uses the RGB LED behind the tube window to display the type of MIDI (PC, CC, or SYSEX) message received.
Typical behavior when a MIDI message is received is as follows:
This menu can be used to set the MIDI PC number associated with each ReVolt Channel (including the Boost state per channel) and the Bypass Mode The Default MIDI PC values are as follows :
|Channel A||Channel A+boost||Channel B||Channel B+boost||Channel C||Channel C+boost||Bypass|
While in this setup menu, pressing a footswitch will set the pedal for the message to be programmed: Corresponding LEDs will light for 1s before displaying the current assigned PC number for this channel
Please note, by default the MIDI PC start value is set to 0.
This menu page allows the user to configure the starting MIDI PC message value when pressing one of the 3 channel footswitches. PC messages sent are as follows:
|Channel A||Channel A+boost||Channel B||Channel B+boost||Channel C||Channel C+boost||Bypass|
|Guitar||PC number||PC number + 1||PC number + 2||PC number + 3||PC number + 4||PC number + 5||PC number + 6|
|BASS||PC number||-||PC number + 1||-||PC number + 2||-||PC number + 3|
The current PC number is displayed via the channel LEDs
The PC number can be incremented by pressing footswitch A,B or C
FS A = -1 FS B = +1 FS C = +10
Note: If you program the pedal to go further than max permitted MIDI PC starting value (122 for ReVolt Guitar, 125 for ReVolt Bass), it will revert back to the first option and vice versa.
Please note, by default ReVolt’s MIDI Channel configuration is set to 17 (OMNI)
This menu page allows the user to configure which MIDI Channel is utilized by ReVolt. The available MIDI Channel values within ReVolt are as follows:
|0||1 to 16||17|
|MIDI OFF, only THRU active||MIDI Messages are received and sent on this channel number||OMNI : MIDI messages are received on all channels and sent on channel 1|
The current channel number is displayed via channel LEDs
The channel number can be incremented by pressing footswitch A, B or C
FS A = -1 FS B = +1 FS C = +10
Note: If you program the pedal further than the max allowed number (17), it will remain set at 17; the same behavior is consistent for minimum values.
Please note, by default ReVolt’s default FX Loop State is set to All On.
Using this setup menu allows the user to select the FX loop state for each channel, when not using the 4CM mode.
Once inside the menu, if the Channel LED shows ON, the FX loop is active for this channel. Press the corresponding channel footswitch to toggle between the ON/OFF FX loop states for the associated channel.
Please note, by default ReVolt’s default FX Loop CC state is set to 14.
Using this setup menu allows the user to select the FX Loop CC state per channel. The CC number is displayed and incremented in the same manner that the MIDI PC number is actioned. For further details, please see the “PC Number” section.
Using this setup menu allows the user to view the current Firmware version installed on the ReVolt unit as well as options to action a Factory Reset.
Upon entering this setup menu, the current Firmware Version number is displayed on ReVolt’s channel LEDs.
To action a Factory Reset, press Channel A’s footswitch 3 times. With each press, the Channel LED color shifts to white. After completing the sequence, the tube window will show white and the Channel LEDs remain on for 2 seconds indicating that the factory reset has occurred correctly. Once the Factory Reset has been actioned, the unit will resume to display the current Firmware Version across the channel LEDs.
