The EFX-Bumper is a compact solution for guitar players who use multiple effects pedal loops, but have limited pedalboard space. The EFX-Bumper can switch between up to four pedals or groups of pedals, using a single footswitch to cycle between the loops. This allows you to connect a wah pedal to loop-1, distortion to loop-2, modulation to loop-3, and chorus and delay pedals to loop-4; activating a loop is as easy as hitting the Loop Select footswitch until the LED for the desired loop illuminates. Multiple loops can be engaged at the same time, using 3-position assign switches that determine which combination of loops activate together. A second footswitch can be set to engage all loops at once, or bypass them completely. Compact and rugged, the EFX Bumper is built with 14-gauge steel and heavy duty connectors and switches, and is powered via a standard 9V power supply.
