Chorus guitar pedal effect, offering new ways to shape your tone. Switchable Slow and Fast speeds with independent Rate and Depth controls let you dial in the perfect sound for your music, while the Wave toggle switch lets you select between traditional Sine and Triangle waveforms. The Sensitivity control allows modulation rate changes based on your playing dynamics—dig in and the intensity of the Bubbler increases. The Bubbler Chorus is an all-original Fender circuit. The chassis is crafted from lightweight, durable anodized aluminum, and the Amp Jewel LED gives your pedalboard the classic Fender look. The LED-backlit knobs show your control settings on a dark stage at a glance. At the back there are switches for LED On / Off. Bubbler is a true bypass, equipped with one ¼ '' input and two ¼ '' outputs. It is powered by a 9V center negative adapter (not included).
