The FM4 puts 16 extreme guitar effects in one box, with 20 presets, and 4 footswitches. The chosen sounds are wild and often spacey and include emulations of vintage synth sounds such as the Prophet 600 and Arp Explorer. Plenty of Wah to play with and true bypass switching. Some of the sounds are inspired by Frank Zappa and Robert Fripp.
