Smaller is better sometimes!  In this case, the Night Light Jr attenuator packs a punch in a tiny package. Swart wanted something to hide in the port of the ST-6V6se, Atomic Jr, STR-Tweed, and STR-Tremolo.   Something more simple, bare bones, something designed for the low watt sect.  The Night Light Jr can attenuate low watt amps or tossed within any 4-8ohm amp that is 15w or less.  Sounds sublime and even has some of the Night Light Blue Magic while at work.   Less features than the standard Night Light and really designed for mounting vs stand alone.  But we're really digging this little beast and loving the way it brings that Swart Low Watt breakup at more manageable levels for those in need inside the smaller combos.
