Revv AmplificationGenerator G25 25W Tube Guitar Amp Head - Black
1/5
Independent shopping perspective
The Korena take
Revv’s Generator G25 puts a two-channel tube head, direct recording tools, and silent-operation routing into a 15.5 lb format. Its Blue clean and Purple high-gain channels share a three-band EQ but retain independent master volumes, Bright switches, and channel-specific voicing controls. Choose 5W or 25W output, add the onboard reverb or noise gate as needed, then use the serial loop for external effects. Built-in Two Notes Torpedo cabinet simulation, reactive load, IR loading, and a headphone output support cabinet-free practice, recording, and direct output workflows.
Strong match
Who this is for
- Home practice or recording sessions that require headphone use and silent operation.
- Stage rigs switching between Blue clean and Purple high-gain settings with separate master volumes.
- Direct-output setups using the built-in Two Notes Torpedo virtual cabinet section.
