The ENGL Z-5 Custom Footswitch is designed for ENGL amps that are equipped with the 9-pin Custom Footswitch Port.
The ENGL Z-5 enables you to select 4 channels directly by combining the Clean/Lead channel switching and Gain Lo/Hi switching. You can remotely control 2 other functions (e.g. Reverb and VLS on the Screamer 50 models or Contour and Master A/B on the Ritchie Blackmore Signature amp). Power for the footswitch is provided by the special connector cable.
