I think this pedal could pair greatly with any guitar player! No matter what style of music you play, this baby will accommodate you in every way. I just got my boss yesterday. I've been playing with it non-stop!! There is a bit of a learning curve, but as is with any new piece of gear. Part of the fun is learning it though. My one small complaint is this: for the price you would think it comes with an A/C adapter but it does not. It does come with 4 AA batteries though. Other than that this is a bad ass piece of gear!!! I'm super glad I chose to get this model. The factory presets alone will keep you entertained for hours, then comes the joy of creating your own patches. I highly recommend this pedal. I can't wait to discover more in depth about it and get behind the real science of how this thing works. Shout out to zounds for making my dreams come true! I've been dreaming about building my own studio for a long time. I discovered this website through a friend about a year ago, and it's because of this site I'm able to make all of this happen. In the last year I've come to own almost everything I need. Thank you zounds!
Musical Background:
I've been playing music for over 10 years. I play guitar, bass, drums, and I mess around a little with the keyboard.
Musical Style:
Rock/alternative/ambient/ I kinda mix a little bit of everything together. I don't have just one particular style.
