Hi, I recently bought a big muff bass distortion, I was not really sure about buying it but i tried it and it really worked well with the bass lowest frecuencies. That´s the main problem about buying pedals for bass, they don´t work well with low frecuencies. I´m looking for a good professional compressor and the black finger looks like it could work, but i´m not really sure about how it will work with low frecuencies of the bass. I hope you can answer my question
