Classic Digital Distortion FX Bit-Crushing from 24 Bits to 1 Bit Sample Reduction from 48 kHz to 110 Hz Built-In Filter for Coloring Artifacts Innovative Sample Rate Tuning Mode Preset Saving Expression Pedal Control Power Adapter Included Get an old-school bit-crushed and sample-reduced sound into your pedalboard with the Electro-Harmonix Mainframe, a powerful but easy-to-use pedal for electric guitars. Bit Crushing and Sample Reducing are old-school digital effects that create arcade-like, glitchy distortions by affecting properties of digital audio. In addition to classic sounds, the pedal sports some interesting features in-line with EHX’s experimental ethos. Fine-tune digital audio artifacts with a selectable filter switch, or use the Sample Rate tuning mode to actually match your sample reduction to specific musical keys. Save your favorite sounds as presets, and control whole swaths of them at a time when you connect a separately available footswitch. You know what isn’t separately available? The power adapter. Like many EHX pedals, MAINFRAME ships with its own power adapter, so you don’t have to purchase one separately. The Mainframe’s selectable High-, Low-, and Band-Pass filters let the user shape the artifacts of the bit crushing and sample-rate reduction.In Sample Rate tuning mode, the pedal analyzes your input signal in real-time and sets the sample rate to match the pitch of your signal, or a defined interval above your signal; use this for creative effects, such as setting the sample rate to match the key of a song, or continually adjust the sample rate based on what you playA programmable preset setting allows you to save your soundAn expression pedal setting can control any combination of the Mainframe’s knobs with an external expression pedalSample Rate Reduction from 48 kHz to 110 HzBit Crushing from 24-bit to 1-bitUPC: 683274012315
