Makes your Amp1 much more flexible, as you are able access features that are only available in a MIDI enabled set up, or using BluGuitar's pedal board. I'm now able to crank the Amp1 main master out, for power amp saturation, and reduce the 100 watt output volume greatly via the Power Soak feature on the Control1, down to ideal levels for home use.
The unit is micro pedal sized,well made and takes operational power from Amp 1.
Really useful bit of kit.
Hopefully they have sorted out the supply problems to other retailers, as BluGuitar don't appear to ship directly to non-EU countries?.
