Independent shopping perspective
The Korena take
Walrus Audio’s 385 MKII is an overdrive pedal with two selectable Volume and Gain settings, giving you A/B changes from the footswitch. Separate bass and treble controls replace the original single tone-control approach, so you can shape low and high frequencies independently. For more drive, the 385+ switch adds another gain stage at the input. It runs internally at 18V and uses soft-touch relay true bypass, with 1/4-inch unbalanced input and output connections.
Strong match
Who this is for
- Footswitching between two stored Volume and Gain settings during a performance.
- Shaping bass and treble separately while setting an overdrive sound.
- Adding an extra input gain stage using the 385+ switch.
