JMS WoodWorx / Groovetank Basses in Lakeside operates a luthier and custom woodworking studio from Suite 16 on Winter Gardens Blvd, building handcrafted electric bass guitars alongside bespoke furniture and cabinetry pieces. The dual-discipline shop shares East County San Diego's artisan woodworking corridor with The Wizard Of Wood on CA-67, where specialty milling and turning operations serve a similar custom-order clientele. Groovetank Basses produces instruments from individually selected tonewoods — alder, ash, and maple — shaping neck profiles, routing pickup cavities, and applying hand-rubbed lacquer finishes in the same workshop where the WoodWorx side fabricates furniture commissions. The Winter Gardens Blvd location sits within the commercial strip that feeds into Lakeside's dining core, including Eastbound Bar & Grill on Maine Avenue where live-music nights showcase the kind of instruments the shop builds. Each bass guitar ships with Dimarzio or custom-wound pickups, bolt-on or set-neck construction, and hand-leveled stainless-steel frets dressed to sub-thousandth tolerances.
