The Bondi Effects Sick As is the overdrive that virtually gave birth to Bondi as an effects manufacturer. The Sick As is dual-function, so you can get the most out of your overdrive; operate it as a clean boost or dial it up to the highest-gain overdrives imaginable. You can even blend the two together for a unique balance. Hit the toggle switch to change up the tonal characteristics of the Sick As, and then dial in the perfect frequencies using the overdrive's powerful two-band EQ, which has up to 15dB of treble or bass. And, last but certainly not least, the voltage is boosted internally to 18v for tons of headroom and clarity.
