Independent shopping perspective

The Korena take

The American Ultra II Jazz Bass in Sinister Red is a right-handed, four-string model with two Ultra II Noiseless Vintage Jazz Bass pickups, a pan control, and active/passive switching at the master volume. A 3-band active EQ, passive tone control, and two-position midrange selector place broad tone adjustment on the instrument itself. The sculpted alder body joins a quartersawn maple Modern D neck and 10–14-inch maple fingerboard, while the 4-saddle HiMass bridge supports either listed stringing route.
