Multi-veined Reverb Guitar Effects Pedal with High Performance Reverb Function for WALRAS SLO Replica Version. Turn this knob to the maximum and it will feel like an organ. For example, after adjusting the maximum, its adjustable range of the knob is from the left to the right, but if we preset that we press and hold the pedal, adjust the depth knob to the minimum, and then release the pedal, its adjustable range is subdivided.
