While it is possible to slap a semi hollow bass, the slap sound on these instruments might be less pronounced or different compared to solid body basses. The construction of a semi-hollow bass, which features a hollow or semi-hollow body, may result in a warmer, more resonant tone with less attack and definition compared to the brighter, more percussive sound often associated with slapping.
Some players adapt their slapping technique to suit the characteristics of semi hollow basses. They may adjust their attack, damping, or hand placement to achieve the desired sound. Additionally, the choice of strings, pickups, and other components can influence the overall sound of the bass and the effectiveness of slapping techniques.
Overall, while slapping a semi hollow bass is possible, it might not produce the same results as with solid body basses and may require some adjustments in technique or setup.
