I sold my stingray to get a thumb bass . If you into slap this bass is a beast , it also sounds spectacular finger style . If you play r&b... rock ... funk ... jazz . Reggae .... blues this bass is tone monster . The action on my bass is right on par with my Alembic Essence . It’s fun to play ... beautiful craftsmanship... zero neck dive . That’s why I got 4 string
The only complaint I have is this beautiful bass didn’t come with case. I had extra case that had beater bass in it . To me a bass of this quality should not have gig bag
The wood is beautiful... the craftsmanship impeccable.... the action is low with zero free noise . Its extremely fun to play and sounds amazing
Ease of Use
The bass is simple with 3 knobs .. Vol... pick up blend knob .... and stacked knob for bass/treble . I love the bass just as it is there is nothin I would change
The craftsmanship is impeccable
For a bass of this quality the price is fair
