It is designed to replicate the synchronized Tremolo and Vibrato circuits common in vintage 60’s amplifiers, offering the ability to duplicate various modulation tones and create new ones. The pedal features two footswitch buttons for bypass and speed control, allowing users to switch between two different Speed and Vibe settings while sharing a common Tremolo control. Additionally, it includes switches for fine-tuning the vibrato, adjusting the vibe’s tone, and sliding the phase between the Tremolo and Vibe LFOs. The pedal also offers a master volume control for balancing or boosting the volume compared to when bypassed. Other features include LED side-illumination of controls, 14-gauge steel housing with magnetic battery access, and true bypass switching. The pedal also includes Amptweaker’s standard effects loop with Pre/Post options, making it easy to add distortion, delay, EQ, or other effects to build a customized tone.
