The first unit in the Zoom Studio line, the 1201, features a total of 363 effects settings arranged in three banks. Bank A is devoted to the unit's 11 different reverb types. Banks B and C each contain 11 different modulation effects, some of which are unique (chorus, pitch shifter), others of which are combinations of effects (chorus-delay, flanger-reverb). The 22 modulation effects contain a few novel settings, including simulations of lo-fi audio gear and a karaoke machine. In addition to the usual controls, such as input/output volume and effects mix, the 1201 also includes a "character variation" knob that allows users to choose between 11 variations for each of the 33 effects
