I have a Fender Rumble 200 combo (15”) and a 210 Rumble cabinet (2x10”). The rig is fine now, but since I’m always wondering about the next gear I’m considering how I might mod the amp to use it as a combo amp or a 15” cab. Could I just add a switch from the input signal to either go to A. the amp (and then the speaker), or B. the speaker directly bypassing the amp? I saw some videos on YouTube, but wasn’t impressed so I’m open to other suggestions. Thanks!

Yeah, darrell, it's definitely a modification, so be sure the warranty has run out before doing this. See the Modifications section of the Rumble Club Wiki, page linked in my signature, for links to "separating a combo amp and speaker. Several have done it. Also, drop by The Rumble Club and show us photo and get a club number. .
