Hello, I appreciate any insight here. I've been running 2 amps in stereo for years (vht d60 and Mesa single rec) with an aby box. I recently got a mark iic+ and decided to throw it in the mix. Anyway, I kept my two amps in the aby and then plugged the c+ into my stereo chorus that is in the effects loop of my recto, I noticed when I change channels on the recto it changes the channel on my c+. Why is it doing this? Is the c+ bypassing its preamp and using the recto preamp as a slave or something? I intend to eventually get a voodoo amp switcher but in the meantime any suggestions or advice would be appreciated.
