Often players comment that OD pedals sound great when the amp is already being pushed. I have rarely, if ever, played where my amp was turned up enough to get natural overdrive. I play an Alessandro Working Dog, 1x12", 2x6L6. On a scale of 1-10, I usually have the amp set: Volume=4, Treble=6, Midrange=7, Bass=2,Final Output(think master)=1. I prefer to play with my guitar volume set between 7-10 and vary my picking. The small bars, restaurants, beer joints, country club event rooms, etc., will not handle more volume than that. The clean headroom is good for cocktail jazz, pop and country. However, I want to get those nice Robben Ford sounds and the Santana sounds. Based on the threads in this forum I am considering the Dumb Box, Zen, Ethos, and Plush Drive. I'm leaning towards the Plush Drive. What would you do?
