Fender Mustang GT Firmware Version 1.5.20 (Oct 9, 2017) New Effect Models Fender Harmonic Tremolo: Straight from the great Fender “Brownface” amps of the early 1960s, this tremolo effect alternately emphasizes high and low frequencies for a distinctively swishing and almost phaser-like sound EQ 5 Graphic: Inspired by the EQ from the Mesa Boogie Mark IIC+ amp, this five-band EQ is specifically voiced for guitar EQ 7 Graphic: Inspired by the Boss GE-7 pedal, this seven-band pedal EQ is voiced specifically for guitar, with fine sonic tailoring EQ Parametric: Three-band equalizer with parametric mid control, ideal for dialing in an exact mid-boost frequency for solos or for creating deliberate feedback Vibe Unit: Inspired by the classic pulse of a Uni-Vibe pedal Octobot: A distinctive octaver effect with prominent one-octave-down plus subtle one-octave-up capabilities for otherworldly “synthesized” tones Envelope Filter: Automatic wah effect inspired by the temple-of-funk 1970s popularity of the mighty Mu-Tron III pedal Round Fuzz: Inspired by the 1969 silicon-transistor version of the venerable Fuzz Face distortion unit VariFuzz: A Fender-created fuzz effect similar to Round Fuzz, with the addition of variable tight-to-loose bass tonality Improved Bluetooth connectivity for devices running Android version 6.0.1 Improved parameter sensitivity for several amp models and effects Fixed issue with 60’s British amp model where Bright Switch appeared to be non-functional. This is a subtle effect that selects between Normal & Top Boost channels.
