Know before you buy
Yes, it requires the included 12V DC mains adapter to properly power the 12AX7 tube. Using a standard 9V pedalboard power supply will not provide enough voltage for the tube to operate correctly.
Absolutely. The unit features an integrated analog cabinet simulator and an XLR DI output, making it designed specifically for direct recording or sending a signal straight to a front-of-house mixer without needing an external amplifier.
The dry/wet blend allows you to mix your clean, unaffected bass signal with the processed preamp signal. This is particularly useful for retaining low-end clarity and punch when using the higher-gain distortion channels.
The signal path is fully analog, utilizing a real 12AX7 tube to generate its warmth and harmonic character. While it includes MIDI integration for control, the core tone generation is strictly analog.
Yes, the ReVolt Bass includes an effects loop (FX Send/Return). This allows you to insert your favorite modulation, delay, or reverb pedals directly into the signal chain after the preamp stage.
The three channels are inspired by legendary bass amp topologies, ranging from a clean, modern sound to a classic vintage growl and a high-gain distortion. Each channel is designed to cover a distinct sonic territory, from clean funk to aggressive rock.
