Source Audio SA243 Vertigo Tremolo Pedal Overview
The Source Audio Vertigo Tremolo is part of the One Series, new for 2015. It is simple to use, with controls for DEPTH, SPEED, SHAPE and OUTPUT. This simplicity does not affect versatility, however, thanks to its three modes. NORMAL gives you a standard amplitude modulation, HARMONIC bounces between high and low frequencies for a phaser-esque sound and BIAS, which gives a cinematic, bluesy sound. The SHAPE knob gives the Vertigo even more scope, allowing you to morph the shape from a Sine Wave to a Square and Reverse Saw Tooth wave.As with other One Series pedals, further parameters and options are available with the free NEURO software. This lets you tweak the Vertigo Tremolo to the perfect sound for you.
