What does the Warp Drive Switch do? How is it best used?
When the Warp Drive is OFF, the normal mode of the Modern channel is a very clean, pure boost. It really retains all the tonal characteristics and punchy signal of the guitar itself. Now imagine all those same characteristics, but when you turn the Warp Drive switch ON, you get some overdrive and about a 3 dB level jump as well. This can be useful when running amps that may not still provide enough gain/distortion when being pushed or if you simply want a bit more drive. For example, some Fender amps will benefit greatly from use of the Warp Drive. I’ve found that Marshalls don’t typically need it for my use.
