3. It's a Magic Number

Center stage on ReVolt Bass are a trio of tonally-district channels inspired by an Ampeg® SVT '76 and a Marshall® 1992 JMP Super Bass Mark II, plus a custom proprietary high gain bass amp, specified for the exacting needs of the modern bass player.

• Channel 1/Classic Clean is - put simply - iconic, delivering the thump, full-frequency response and power synonymous with channel 1 on the legendary Ampeg® SVT '76. A titanic tone guaranteed, oozing with rafter-rattling low end, punchy mids and buttery smooth highs.
• Channel 2/Vintage Dirt is your weapon of choice in moments where you just need to cut above the rest. Taking inspiration from a Marshall® 1992 JMP Super Bass Mark II, this is the epitome of a larger-than-life bass tone topped with lashings of vintage dirt.
• Channel 3/Modern Drive delivers ultimate flexibility for the forward thinking player. Based on an original Two notes design, it’s super-tight with an abundance of gain for a thick “gained-to-the-max” tone. For added tonal versatility, there’s a switchable Dry/Wet Blend that delivers precision and clarity when you need it.
