OK guys….I think I’ve about got this nailed down but wanted to clarify a couple of things and hoping to give it a try this weekend at some point in time and then it’ll probably be questions regarding blocks and inputs and outputs in which I will start a new topic as this one will be a mile long. And yes, rd2rk that clarification was helpful.
So I’m really leaning towards a 2 cable setup just running from the Helix mono out to the return on the amp head and bypassing the preamp altogether rather than using a 4cm and here’s my thought. I don’t turn that amp up much past 1 ½ or 2 for a room level volume so if I’m not driving that amp head at a high volume, going through the physical preamp on the front of the head (to me) wouldn’t make much of a difference in sound or tone or whatever you want to call it. I realize that I can’t (or shouldn’t) use amp modeling in the Helix and run that into the front input of the amp and double dip. However…(stick with me, I’m on a roll) If I ran the 2 cm and strictly used the effects loop on the back of the amp for power into the 412 cabinet and taking the physical preamp (and front knobs) out of play, I should be able to use amp modeling as well as effects. My little monkey brain says that in the Helix chain I should be able to put the effects that would normally go in front of the amp (distortion and what have you) and then insert an amp modeler and then the effects that would go after that like chorus, delay, etc… or, for that matter put whatever wherever I wanted to, Yes? So a chain would look like:
Guitar or Multi>Distortion>PreAmp>Delay>Chorus>Not sure if this would stay at Multi or I should use something else.
The reason I’m questioning this is that in the first reply, Silverhead said: “By not using 4CM you will be missing out on the ability to use the amp modeling in Helix. Using both a Helix amp model as well as your Marshall preamp simultaneously will sound horrible. Also you will lose the ability to position your FX blocks either before or after the preamp section of your Marshall. You will be restricted to using your Helix as an FX only device, with all FX blocks positioned before your Marshall in the signal chain.”
I don’t understand why you couldn’t use amp modeling if you were using a 2 cable method. The second sentence I understand 100%. I also understand that I will lose the ability to position the FX blocks before or after the preamp section of my Marshall…BUT I could place them before or after an amp model in the Helix chain on a preset or in creating a new patch or whatever Helix calls it.
Now, providing that I’m right about all of what I said above…rd2rk, you mentioned the pre-amp, full amp, and full amp+cab in the modeling choices. If I’m using the 2203 strictly for power and going into a 412 cabinet, would I only use a pre-amp model? OR...should the full amp or Full amp+cab be in play here? Just using the effects loop and bypassing the physical preamp would make this a FLAT power amp, correct?
And last question….If I’m using the 2cm, is there anything that I won’t or shouldn’t use such as IR’s or anything else you can think of?
