First impression of the TC electronic Tube Pilot Overdrive - wow. It is awesome sounding, in our opinion of course. You have your own ears so test it interactively on the TonePedia player and make your own mind. At a killer price of approx 50$, this 12AX7 tube driven overdrive is a steal. It is so easy to get a warm sound from this pedal, it is great for solo or rhythm and delivers fantastic vintage style tone. We see it as a great option for blues and classic rock players who seek for a dynamic and inexpensive tube pedal. Please take into account that the TC electronic Tube Pilot Overdrive does not take batteries.
