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.

Shop Scott's Rig







Zach loves his Sovtek Mig 60 head, which he plays through a cab he built himself at a pipe-organ shop in Denver. Every glue joint is lined with thin leather for maximum air tightness, and it’s stocked with Celestion G12M Greenback speakers.
