The Atlas Solo JB350/CM4 is a solid top fretless bass that takes advantage of innovative Breedlove bass bracing featuring the JLD Bridge Truss system. Voiced with the textured response of mahogany, the concert deep body with monitor soundhole sounds great acoustically and is ready to plug in and play out. This Breedlove guitar is a high-performance instrument offered at a price that working musicians can afford. The L.R. Baggs LR-T CV Tuner Preamp features a 3-band EQ, presence, phase, and a stealthy chromatic tuner.
