Working great for looping in an older noisyish pedal
I'm using this in a front-end guitar effects chain to switch in a side loop with a vintage EHX Electric Mistress. It does the job with excellence, with no added interference or discernible signal loss on pass-through. With the loop level controls I can give the output signal from the Mistress the slight boost it needs to even out the effect/no effect signal level, and I can blend wet and dry signals to color the signal over a richer tonal range than running straight through the Mistress. The LS-2 provides that boost while also reducing interference noise in the Mistress loop (with only very slight audible loss of desirable harmonics compared to the Mistress in direct line). So this setup unexpectedly saved me from having to buy and fuss with a noise gate in the chain. This noise taming effect allows me to run the Mistress through some more gainy amp settings that sounded like crap before. Expected Boss high quality in the case and firm handling, smooth response, noiselessness movement in the switches and pots. So far I could not be more satisfied in this application, and with the unexpected noise control benefit (though this might be a chance outcome in my particular array that perhaps not everyone should expect) pushed me give it a 5.
