Every pedal board needs a good buffer. Buffers balance out your impedance and get that loss of highs back on track, especially with multiple pedals and long cable runs. The quality of guitar cables varies so if you have ever plugged straight into your amp and then back into your board, you know what I mean. The SOS is exactly that, a pedal that will rescue your tone. There is one knob used to subtly vary the focus of your high end. Some buffers can over-do it and some not enough. The SOS control will allow you to dial in the highs to be exactly how you need them and you won’t get that crazy interaction with Fuzz pedals and Wah pedals.
SOS Control – subtly adjusts the amount of top end in your signal path to be balanced.
