Crazy Screamer

The Movall MP-315 Overdrive is a compact overdrive pedal featuring Drive, Tone, and Level controls, along with a Hot/Warm voicing switch that provides two distinct gain and EQ characteristics. It is designed to deliver low- to medium-gain overdrive tones, ranging from smooth breakup to more saturated drive sounds. Based on its control layout, voicing options, and stated emphasis on warm, mid-focused overdrive, the MP-315 appears to be inspired by the Ibanez Tube Screamer family of circuits, although Movall does not specify an exact model or direct clone relationship. The Warm mode provides a smoother and fuller overdrive response, while Hot increases gain and output for a more aggressive sound. The pedal features true bypass switching and a compact aluminum enclosure designed to fit easily on crowded pedalboards.
