B/guitar processor in my pedal chain?

II 'm a b player. have a b processor and a guitar processor. They both sound great by themselves. But both of them sound thin, and coax a huge amount of feedback when I add them to my chain of effects on my pedal board. My effect are a (in order) a crybaby, an Aphex Punch Factory Compressor, and a Boss B EQ. Are processing pedals just not meant to be used in conjunction with other effects?
