Frequently Asked Questions
The clean channel is surprisingly good with single-coils, offering a clear and articulate tone, although it can get a touch grainy pushed hard.
It's best suited for time-based effects like reverb and delay, as the impedance might not be ideal for drive pedals.
The 20-watt design means it has significantly less headroom than a larger amp, but it makes up for it with a quicker onset of natural overdrive.
