Line6 LFS2 Catalyst Footswitch

Great price, it works perfectly. I am using it with my amp Catalyst 60 and I think that it is a necessity because it is so nice to be able to switch effect on and off while playing. With channel switch you can easily switch between two presets, while the effect switch can be appointed for multiple actions (this refers to my amp catalyst and can differ with different amps). I don't know how well does it work with other amps but I can assure that build quality is great.

Necessary on stage, practicing at home can also be done without

this is a super guitar amplifier, many options of different sounds, the only drawback is that you can only use the effects 1 at a time, you can set multiple settings, but you have to select them manually with the app,
this can probably be solved with a different foot switch. I have the foot switch with only 2 buttons
