Yama is a preamp boost made to kick your pedals and amp in the ass.

Need more lows, need more cut and a punch in the face? Need to lift your signal up and breathe more life into your tone because you have 8+ pedals, put this at the end of your chain and just use is as an always on tone shaping tool. It will turn your fuzz’s and distortions into hammers of tone. Or maybe just needing a thicker clean boost for Single Coils and Ambient Drone, try this in front of your modulation pedals for some more tone-shaping capabilities.
