THE ABCADABRA: MIDI A/B/Y SWITCH AND LOOP INSERT
The ABCadabra does all switching with fast relays to make the audio connections so there is absolutely no modification of the audio signal. This makes it the the ideal device for tone purists who demand direct connections between guitar and amp when bypassing effects or switching between amps. Midi control is realized via both Program Change commands as well as Controller Change messages found on most modern MIDI controllers.
When used in AB mode (A, B, or Both), the Common Jack is used to connect to the instrument and the A and B jacks are used to connect to the two amplifiers. When used this way, the output that is shut off is shorted to ground so there is no noise coming from the unused amp. In this mode of operation, the device can also be used to switch multiple instruments to one amp, or in any other number of configurations.
