Korora’s new harmonic tremolo was a trip. The Merlo offered three different EQ profiles, three different sine waves, and tap tempo. During the demo we heard everything from subtle and warm to choppy and unsettling. The color control acts somewhat like a tone knob by adding in more harmonic content. Streets for $249.
