RJM Music Technology


The Mini Effect Gizmo is the newest switcher in the RJM Music lineup. This compact switcher is small enough to be placed on a pedalboard or in a rack drawer alongside your pedals. With the Mini Effect Gizmo, you can switch five pedals, switching any or all of the pedals into your signal path with a single tap of a MIDI controller button!

  • Control your pedals on a pedalboard, in a rack drawer, or wherever. The Mini Effect Gizmo is small enough to fit almost anywhere
  • One button press on a MIDI controller can turn on any or all of the 5 connected pedals. No more pedal tap dance!
  • 5 true-bypass audio loops allow you to preserve your guitar's tone. Unused effects - and the cables that connect them - are switched completely out of your signal path
  • Relay-based switching offers the most transparent sounding audio switching available
  • The built-in audio buffer improves tone even further, reducing level and treble loss from long cable runs
  • Click Stopper™ circuit insures quiet switching
