The H box is great for an ‘either/or’ type setup.


the ABBA switch is a simpler version of the AC/EC, no shared loop. just two inputs and two outputs, selectable on stomp, and the other output is muted. so its like having a MAB 2in1 and a MAB 1in2 out in one unit.

if you have two guitars that will use different amps, or run a banjo to a DI or something and would only need one available at a time, the ABBA switch is the switch for you. also available in momentary form (for some of you vegas/showboat type guys who need a stab of acoustic guitar) just shoot me an email for the momentary version

The approx build time for an ABBA switcher is 1 week
