I have owned Cerberus for over a year, during which time I had the opportunity to test it thoroughly. Pros: - overall solid build - delay/reverb unit is very decent (FW upgrade also adds the Shimmer effect, but at the expense of Reverb) - possibility to use Cerberus in manual mode (as a separate box), or use preset mode Also - possibility to upgrade Firmware, in which interesting functions are added, e.g. Shimmer effect, global TAP tempo, possibility to use an external 2-button footswitch in the expression input and switch tap tempo/analog boost/reverb/mod FX with it, etc. (some are editable only via PC software). - Cerberus can be controlled via MIDI, or from Cerberus it is possible to remotely control another device via MIDI in preset mode (this is how I control Whammy) - possibility to connect effects directly, or use the 4-cable method. -IR, which can be changed Disadvantages: -analog overdrive and distortion section. Overdrive is usable as such, but Distortion is very vague, I recommend using an equalizer after this section (buy a pedal, since the effect does not have an equalizer in itself) -the switch used for TAP tempo could be "softer" or the type used for momentary switches would be suitable -modulation effects are a bit vague, their sound is vague, but that's probably a matter of taste. -Cerberus also lacks overall output volume, which is not a problem when playing live, but when practicing at home with headphones, it would be appropriate to adjust the output volume. Overall, however, it is a good effect, for good money. If someone likes the Distorion type, they can only be satisfied :)
