SRH500F Fretless Acoustic-Electric Bass Guitar Flat Natural Browned Burst. If you crave a new bass tool to enrich your creative palette, the Ibanez Bass Workshop may have already built your next instrument. This new product group focuses on combining unusual concepts with the bass-building virtuosity on which Ibanez has built its reputation. Unlike other hollow body basses, the SRH boasts a unique concept: the integration of the authentic feel expected in a hollow body and the key features that distinguish SRH as a contemporary bass. With its sleek, compact, comfortable lightweight body, the SRH breaks another boundary to open up your playing. With its maximized hollow space, Spruce top and Mahogany back and sides, the 55 mm-thick semi-hollow body delivers a rich acoustic tone. The specially designed forearm contour on the body top offers playing comfort, and adds an elegant accent to its appearance. A bound Rosewood fingerboard features black fret lines that balance competing goals for guiding positions and keep the fretboard from disturbing the atmosphere expected in a fretless layout. A contoured neck heel is applied to create a deep neck joint with unfettered access to upper frets. The custom bridge contains the magic of the AeroSilk Piezo system, which works with D'Addario ECB81 flat wound strings to provide that sense of “air” that characterizes the upright sound.
