The original Mark IIC+ is tighter in the low end and more surgical than the DSL's British voicing. Dropped mid from the original 3.5 to 2 because the DSL's mids are already more prominent and honky — this achieves the signature AJFA scoop. Pulled gain back from 8.5 to 6 because the DSL's Ultra Gain channel saturates faster than the Mark IIC+'s lead channel. Presence reduced by half a point to avoid the DSL's tendency toward fizz at high gain.
