What is your opinion of this product?
I love being able to change the switches from latching to non-latching as needed. I finally have a "stop" button for my BOSS looper pedal now! I also tried this with my Peavey ValveKing amp, and it seems to switch to the distortion channel more smoothly than the stock footswitch. Switching back to clean still seems to produce a lag, but maybe a bit less pronounced than before. And yes, once and for all, you MUST have a 9v battery installed for this thing to function...which is why I give it 4 stars instead of 5; I'd much rather use an AC adapter (are you listening, BOSS?). But overall I'm quite glad to have this switch in my collection...I have a feeling it will prove useful in many ways.
