Designing Overdrive Pedals - Understanding Op-amp Gain in the MXR Micro Amp and ProCo RAT

In a guitar pedal, an op-amp is one type of amplification that can be used to produce gain, which determines how much the signal is amplified or boosted. This gain is not constant across all frequencies; the open-loop gain is highest at low frequencies and decreases as frequency increases, a behavior known as its frequency response. The specific gain and its roll-off rate (how quickly it decreases) are critical in shaping the pedal's tone, for example, causing the clipping and distortion that characterize overdrive pedals.
