PEDALS DOUBLE GUN DISTORTION

This pedal will ship with 2 JJ 12AX7 tubes pre-installed. However you can use any 12AX7, AU7, or AT7, you would like. If you feel like the pedal has too much gain for your playing style swap in an AU7, or AT7, into the the first tube slot (the slot closest to the input jack), for less gain. Blues players will love a 12AU7 in the first slot and a 12 AX7 in the second slot, for a lower gain warm, bluesy overdrive.
