What is your opinion of this product?
The Line 6 M9 is a very versatile, easy to use multi effect pedal with many great sounding effect models to choose from. It's true bypass, so it doesn't effect your amp tone, and it's very quiet; no unwanted hiss or noise. I especially like the reverbs and delays. The Line 6 M9 is the perfect multi-effect pedal to pair with the valve amplifier that you love.
