Verified! Works with a NSL-32 or a VTL5C1 but wasn't great. Also tried a yellow diffuse LED with a GL5537 and a GL5549 and opted for the yellow LED and GL5549. It seemed to allow the higher notes to be more present without farting out so quickly. Might try some other LED colours before i commit to boxing though.
Cheers Alex
