--- Update
@rigatti's advice put me on the right track! I needed to hook up the amp to my PC using the USB-B port in the back, and download Boss Tone Studio (specifically the Katana Mk2 version). Under the "Editor" tab, and then the secondary "Send/Return" tab, I simply needed to switch the "position" property to "Post Rev".
Dope. Rock on, friends.
Original Post
Heyo, I hope this is appropriate to post here:
I picked up a Boss Katana MkII guitar amp, and it has a lot of cool features that I'm new to, one being its send and return loop. I currently have it sending to, and returning from, a little Ditto looper pedal. With this setup, it typically allows me to overlay multiple tracks, with each one having different effects (powered by the amp) applied. However, sometimes it happens that switching to another preset channel seems to apply that new channel's effects over the existing loop tracks. It appears to be mainly happening with reverb, but it's not consistent, and I can't pin down what's causing it. Even switching to another channel and back will sometimes solve it.
Any tips or ideas?
It very well may be the case! Apparently, there's a desktop studio app, which might let me move things around. I guess I'll have to decide whether to lug my PC downstairs or my amp upstairs...
Thanks!
