Rotosound RWB1 The Wobbler Tremolo
Rotosound · pedal
The Rotosound RWB1 The Wobbler Tremolo continues the string manufacturer's expansion into effects pedals, applying that established manufacturing background to a classic tremolo circuit rather than a more experimental or unusual effect type. Tremolo works by rhythmically varying a signal's volume, creating the pulsing, throbbing effect associated with surf rock, vintage American amp tremolo circuits, and countless genres since, and the Wobbler's playful name signals the same British boutique-pedal personality found across Rotosound's other pedal releases. As with a phaser or other classic effect built by a manufacturer better known for a different product category, the appeal partly rests on Rotosound's established reputation for build quality translating into this new space.

“The Wobbler's primary use case is adding classic pulsing volume modulation to clean or lightly driven tones, well suited to surf, indie, and vintage-leaning styles that lean on tremolo's rhythmic character”
— from the community notes
“In a chain it typically sits toward the end of the modulation section, often near reverb, since tremolo's volume-based effect works well as one of the final tone-shaping stages before the amp”
