Mr. Black Bloodmoon

Run Mr. Black Bloodmoon after SB|LB Pedals Freq Boost in the signal chain, clear of SB|LB Pedals Freq Boost's own gain stage — goes in the amp's FX loop (or last, into a clean amp)

Red Witch Titan

Keep SB|LB Pedals Freq Boost's clean boost voice out front: Red Witch Titan goes after SB|LB Pedals Freq Boost in the signal chain so its ambient voice doesn't muddy it — goes in the amp's FX loop (or last, into a clean amp)
