OPERATION: VOLUME - Controls the overall output MIX - Controls the balance between Delayed (echo) signal and Input (dry) signal REPEAT - Controls the number of echoes present at the output DELAY - Controls the delay time BYPASS - True Bypass SLAM - The SLAM switch is a momentary, non latching switch that when depressed and held down will set the delay time to its shortest delay and repeats to maximum setting. The result is saturated, runaway echoes. The SLAM effect offers several useful / creative performance applications not limited to incredible lead line emphasis and lead beat punctuation. When the SLAM switch is released, the MR ECHO returns to normal operation
