The Marshall Astoria Dual 30W tube combo is an original two-channel design. Via the 1x12 in. 75W Celestion Creamback, the clean channel ranges from brilliant clean sounds to classic Marshall crunch, and the overdrive channel takes over from there offering plenty of gain and tone for heavier riffs and solos. As well as having the consistent Edge and Power Reduction features, this model also has a Body switch to broaden low end frequencies, as well as a Master volume. On the rear panel of the Astoria Dual is a footswitchable FX loop with Send, Return and Level controls. If unused, the Level control can be used as a volume boost.
