The Greer Amps Sonic Boom is a clean boost pedal from Athens, Georgia boutique maker Greer Amplification, providing transparent output gain for pushing tube amplifier front ends or increasing solo volume without adding significant tonal coloring. The Sonic Boom name implies a dramatic volume enhancement with the clean, transparent clarity of a sonic boom rather than tonal warmth or coloring. Greer builds handmade boutique effects in Athens, GA, and the Sonic Boom is their clean boost offering for players who need reliable, premium boost capability.
The Vertex Effects Ultra Phonix MKII is the enhanced second version of Vertex Effects' flagship boutique overdrive, delivering improved warm, natural overdrive with refined circuit quality in Vertex's premium build standard.
