Radial Engineering Bumper

At night on a stage that is... The Bumper is a compact  instrument  selector  that  lets  you switch between four instruments using a simple footswitch.  An innovative circuit advances through  the  connected  inputs  depending  on what is connected. Full size, super-bright LEDs follow  the  selector  switch  for  instant  visual feedback.
Each  input  features  Radial’s  legendary  Class-A  input  buffers  to  drive  long  cables  without noise, distortion or artifact. Each input is also equipped with either Drag™ control load correction or a TRIM, depending on how it is set.
This allows guitarists or bass players that use multiple instruments to quickly change instruments  while  optimizing  the  load  on  passive pickups or matching the level when using louder active sources.  A dedicated tuner out is always on hand for on-the-fly adjustments.
