So I got a used SYB5 Boss Synth pedal, need it for one song so I bought used. The thing is it always sounds distorted no matter what config I set it at, tried it with pedals in front, in back, and stand alone. Is this common or did I get a bad one? I did read to put a compressor in front and a limiter in back to smooth out the volume spikes but this is distortion, I can deal with the spikes. I'm looking to mix just a little for texture. Thanks in advance for the input!
