Designed for musicians who demand the most from their effects without loosing the tone they’ve worked so hard to define. The sound is "neutral".
The following picture shows how it works.
This is what BP-4 controls.
This picture shows mid control curves (+-7dB@500Hz) when MC-1 is inside.
Finally, you can move the mid frequency when MCP-1 is used (220Hz - 780Hz).
Tomorrow, I will continue :-)
