A) If I want to use the RT50C with a load box:
1) Do I have to modify the amp, so that the built-in speaker is muted? Please describe procedure if this is the case. Can I still easily and safely revert to using the in-built speaker if needed?
2) Do both the 8ohm and 4ohm cab outputs have to be connected?
B) I want to switch amp channels using a Line 6 Helix, but the footswitch port is not directly compatible. Is there an adapter I can buy?
C) Assuming I need to get these modifications made by a specialist, is it cost effective, or am I better off buying a head and separate cab? The amp is sitting in a shop, but no-one is interested, so I'm thinking of taking it back and modifying it.
Thanks in advance.
