Hi all, I am a noobie joobie here so please be kind and thank you in advance for reading this thread.
I am thinking about buying the Helix as a replacement for my pedalboard, I have a Marshall JVM410hjs which I love the tone of and play live with a V30 loaded 4x12. The back connections to the JVM are quite versatile and not only have a programmable serial FX loop but also a power amp INSERT, IN and OUT. I want to run the Helix as the main control (forget channel switching for now) and have Fx pre and post preamp via 4 cable method. Is there a way I can utilize the fx loop and the power amp insert to run preamps from the Helix through the power amp insert (obviously minus cab models) and post fx through the loop. Basically making the preamp on the Marshall JVM another 'preamp' in the Helix? Footswitched in via the loop. So all Helix preamp models go through power amp Insert but by using the loop i can use my Marshall's preamp as an added preamp and having the Fx through it? Maybe I'm thinking backwards here and there is an easier way i.e. normal 4 cable method, just wondered if there was any benefit of running it this way, or maybe using the power amp IN will negate the loop. appreciate all your thoughts and feedback. Thank you for listening.
Both the effects loop and the insert in the Marshall are located essentially in the same place in the circuit-meaning between the preamp and power amp. I'm guessing that the loop is switchable and the insert point is not. If this is the case, then just use either one of them as a standard effects loop for your 4CM connections, but don't muck about trying to utilize both loops as it won't gain you anything except a mess of unnecessary wiring.Go to the full post
