Boss LS-2chat_bubble_outlineFrom real comments

Bassists rely on it to keep low end intact when adding dirt. Many bass players use the LS-2 as a dry/wet mixer because distortion and fuzz pedals often strip low frequencies. By blending a parallel clean signal, they restore bottom end while keeping the wet effect on top. Several call this transformative, saying it changes how they think about pedal compatibility, freeing them from needing 'bass friendly' dirt pedals specifically, and enabling two big muffs or gated fuzz setups with retained low end.

The internal loop normalling trips people up but saves cabling. Multiple commenters repeatedly clarify that you don't need to dead-patch a loop with a cable; leaving send/return unplugged loops the signal internally and acts as a clean blend. This point is corrected several times in the comments, suggesting it's a common point of confusion for new users watching demo videos, but once understood it simplifies setup considerably and is seen as a core convenience of the pedal.

Versatility extends well beyond simple A/B switching. Users describe using the LS-2 for parallel dirt pedal combinations, amp switching, clean boosting, full pedalboard bypass as a safety net, splitting to two consoles or amps, and creative modulation blending. Several call it a 'hidden gem' or their favorite pedal, and one long-time reviewer says it remains essential despite looking visually unexciting, with the mixing possibilities described as effectively endless.
