Good condition, 6,5/10, purple finish, fully functioning except for a broken Stereo/Mono button which is missing, from online: Dunlop has truly captured the classic Tremolo effect found in vintage amps, while upgrading the reliability with modern circuitry. The TS-1 offers both stereo and mono Tremolo effects. The auto-panning stereo mode provides the ability to ping-pong your sound from channel to channel at varying speeds and transitional rates with complete intensity control.
