4-string · Bolt-on
A hand-built replica by Thalassa Custom Basses of Mark Hoppus's (blink-182) iconic plaid-painted 'Groundskeeper Willie' Precision-style bass. Thalassa is explicit that this is a REPLICA - it was never played or owned by Hoppus. Alder body, Mighty Mite neck, a Seymour Duncan SPB-3 Quarter Pound split-coil P pickup, Fender-style hardware with through-body stringing, and a custom hand-painted plaid finish (not a vinyl wrap). Ships with Ernie Ball Super Slinky strings and a Gator bag. $2,750.
