I'am after a parametric EQ and one of the options is the Manley EQP-1A. I've read the online users manual but how can I get my bass connected to this unit. Do I have to use the FX send and return on my amp or is there a possibility that I can connect my bass directly to the "in" on this unit? If I have to use the FX send and return on my amp, Hevos 400D, I can only dial in 50% wet and 50% dry bass sound. This is good for keeping low end with a distortion but I'am not sure if this is a good solution for an eq. I wuill use the eq mainly for altering my sound during songs and not for permanent sound sculpting. Besides an eq I will be having a rack mount compressor and a rackmount distorion unit for "making" my sound.
