Danelectro BT-1 Filthy Rich Tremolo

The Big Joe R-409 Tremolo is an all-analog, vactrol-based optical tremolo guitar effects pedal. You can control the pedal’s modulation effect from 1Hz to 10Hz using the Speed and Depth knobs, while the Shape knob lets you go from a square waveform to a triangular one for amp tremolo sounds emulating everything from a vintage Vox to a classic Fender. The Big Joe R-409 Tremolo features true bypass switching and supports 9V to 18V power supply units.

The Behringer Ultra Tremolo UT300 Classic Tremolo Effects Pedal lets you serve up the classic surf-era sounds of the ‘50s and ‘60s with a modern sheen. Get classic mind-bending tremolo effects reminiscent of vintage ‘60s amps using the Ultra Tremolo UT300’s dedicated Rate and Depth knobs which give you more complete control over your sound compared to a single Intensity dial. There’s also a Wave dial that lets you go from a softer, more triangular waveform to a harder-edged square for that classic transistor tremolo sound.
