This new tiny Quilter "all-in-one" tool sounds promising! I love the idea of a such a small pedal platform amp.
Here is a video. And I added some important information about function of the "FR / CAB" switch.

"Peter from Quilter here, you actually use the CAB mode when playing through a cab and/or you want cabinet simulation through the direct out. It's sort of the default. FR Bypasses it so you can go to an FRFR cab and use outside cab sim. But for a traditional cab you want CAB mode. Cheers"

Hey David, I see the confusion, that could have been worded better. We tried to keep it simple but it didn't serve us well there so here's some more info.... CAB mode turns on cabinet simulation for the headphone/line out and sets up the speaker out to pair with a traditional cabinet. So use it when you're using a traditional cabinet or if you want us to make it sound like you are, whether you're going through an FRFR passive cab, headphones, or line out. FR mode defeats that and makes both the speaker out and headphone/line out totally flat. That might sound like what you want when using a traditional cab, but it's not. The InterBlock doesn't have the full package of tricks in our larger amps to make them tube-like, but it has a few of its own to make it sound awesome and be even smaller. One of those tricks effects how the speaker interacts with the amps. Our larger amp have the same low damping factor relationship with the speaker that a tube amp has. The InterBlock, and the MicroBlock for that matter, have the traditional high damping factor relationship with the speaker that every other solid state amp has. People compensate for that in different ways to make things feel right. Most use digital filters these days. In the past they would leave it feeling stiff and lifeless which is a big part of why most solid state amps feel and sound like garbage. We use a few analog circuits to bridge the gap in the InterBlock and MicroBlock. Those are activated on the speaker out when in CAB mode. Feel free to play through one and try it in FR mode through a tradtional cab. I suspect you'll quickly switch back to CAB mode You would use FR mode if you had something like a Helix with built in cabinet simulation and you just needed a clean power up to power your passive FRFR cab. Long winded, but I hope that helps!
