There are nine choices of chorus, each with a slightly increased rate and depth, rather than a single option coupled with rate and depth parameters.

It's a similar tale with the 11 amp and drive options, although you can alter the gain, EQ and contour of each. The unit also allows you to alter the time of the delay and reverb settings, with their specific number - delays one to nine - being related to the incremental increase in feedback.

It's all self-explanatory, with a pair of effect selectors working in tandem with the display and specific duos of ± keys, but make sure that you store the setting before rotating the second knob back to Play mode - otherwise it'll forget your tone tailoring without warning!

With four footswitches, the unit offers 40 fully programmable patches split into 10 banks of four, selected in the usual way.

There are no operation lights for the pedals, so special attention must be paid to the LED so that you know where you are, and getting to grips with the abbreviations Zoom has used for the unit's features is time well spent.

Comes with 12 months warranty.
