I have narrowed my lead pedal search down to either the Zendrive or Gaspedals Dumb Bell to compliment my OCD V.4. I have heard clips of the OCD and Zendrive ( sounded very nice) but I have not heard anything regarding the Dumb Bell and stacking with other pedals. Gaspedals is offering a version 2 of the Dumb Bell that looks great. I can't decide wich route to go. Obviously if I had more $ I would try both but thats not an option. Any advice would be appreciated. thanks.
