Youtube Channel
“HBB” (Hawaiian Bad Boy) is the creator behind Bad Guy Good Audio Reviews, known for music-first evaluations and a large public FR graph library that many hobbyists use to compare tunings. He’s collaborated widely across price tiers: early hits like Tripowin × HBB Mele and Olina/Olina SE, budget projects with KZ (DQ6S) and QKZ, and more recent releases such as the FATfreq × HBB Deuce and the Linsoul × HBB Jupiter.

Deuce was iterated with FATfreq around their “Basscannon v2” concept, featuring a pronounced, tightly controlled sub-bass shelf below ~150 Hz and often paired with a bass-boost adapter—aimed at delivering slam without swamping the mids. Jupiter is a tribrid flagship (1DD + 6BA + 4EST) with an ~11 dB sub-bass lift, designed for engaging macrodynamics and extended treble air. Across his work, HBB generally favors a warmer, bass-supportive balance while keeping vocals clear and treble non-fatiguing, and he anchors tuning choices to specific music rather than test tones.
