Let me try this again…I have an F-100. It added a nice texture to my band’s sound. My other guitar player says he doesn’t like it much…he says that the overdrive is "sterile" The main problem is that when we rehearse I only have the gain on channel 2 at about "1" on the knob. I just can’t crank it up because it will blow the room apart. When we play live it kicks ass! I can turn it up an it gets better the more signal that is pushed.
