The Engl Z-9 Custom Footswitch is sure to serve you well as the switching center for your rig! With this custom-designed foot controller, you own a general-purpose tool well-suited for operating specific Engl amps via Serial Amp Control (Engl's proprietary data protocol). As an alternative to this, the Z-9 switch can be configured to control MIDI-enabled amps and effect devices. The Engl Z-9 features a unique auto configuration function that, according to the type of connected cord, configures it as an Engl SAC system switching center or as a basic MIDI foot controller offering 10 MIDI patches. Carrying on the Engl tradition of turning out foot controllers boasting rugged design and striking visuals, the Engl Custom Z-9 Footswitch is a very robust device housed in an elegant stainless steel chassis.
