I bought a pre populated Stingray bass 2 band eq , did the offboard wiring and the 1megc reverse audio tone pot works backwards. Any ideas? Turned full clockwise it is most mellow and backed off all the way it is brightest. It is wired as it should be, but I swapped the outside lug wires to see if that would do it, but that didn't work and stopped it from functioning properly. Swapped back, it sounds great, but the tone is going backwards - turned up to 11 delivers the most mellow tone and rolled off gives the most treble boost. Any ideas?
