im currently using a mb115 with a Mbp 112. The 112 sits on top of the 115 making it hard to access the controls on the 115 on tight stages. I was planning on ordering the mbp115 so I could sit the Mb115 on top. However I’m now considering keeping the amp and cab I have and adding the Plex to my pedal board. Is there a way I can run the plex in to the mb115 and bypass the pre-amp stage? For example connect first to the mbp112 and daisy chain to the combo using the output as an input on the mb115.
