NUX AS-4 Amplifier Simulator

The unbelievably simple user-interface comes from our complex Dual FET Circuit Design, but don't worry about what's under the hood.  Just enjoy the  1 Simple Control-Knob,  2 Boost Options, and 2 Bypass Modes. The 2 Boost Modes:  Clean Boost In the Clean mode, Lacerate only boosts the signal, increasing the volume without any sound colorization. For this reason, Lacerate is one of the cleanest "clean boost" pedals available. Crank Boost If you want fat , harmonically rich boost tone, just hold down the foot-switch (1 second) to engage the 2nd stage which adds your overdrive tone. Most boost pedals will only yield about + 20dB maximum, but Lacerate`s Crank mode gives you a whopping + 35dB . From average to huge! Higher Voltage, Increased Headroom & Dynamic     Lacerate has an integrated voltage-doubler which automatically changes 9V to 18V giving you ginormous headroom and dynamic. WARNING: To avoid damage to voltage doubler circuit, please ONLY use 9V Power Source. It will handle the conversion. True Bypass or Buffer Bypass Doubling the voltage to 18V gives you better dynamic, but it also creates a better headroom buffer. A lot of professional guitar players start their signal-chain with a stand-alone buffer. Lacerate has an embedded selectable buffer bypass You can change the bypass mode by turning on the power while holding the footswitch. Summary:  * True Bypass / Buffer Bypass  * 2 types of boost options (Clean & Crank)  * Dual FET Circuit Design for the most tube-like tone in a transistor design
