I really enjoy versatile overdrive/distortion/fuzz pedals and I don't want to use multiple dirt pedals. A rat that goes from clean boost to all out fuzz is the thing for me. Or something like the Catalinbread Giykas with the blend control would be ideal. I need to try it out one day. Anybody here who has the Giykas? What do you think about it? What would really be cool is a dirt box that has an expression pedal input that could control the gain and the volume at the same time. Toes down increases the gain and lowers the volume and heel down decreases the gain and turns up the volume. The idea is that the overall output would be the same, only the amount of dirt changes. Would you buy one? And If there is such a pedal, please let me know. I realize there are drive pedals that have do have an expression pedal input but not the kind I'm after (as far as I know).While you can ride the guitar's volume pot it's not quite the same. The volume usually goes down signicantly or the sound just gets a little cleaner and not all the way.
