Hey. Last few weeks the channel selector switch on my 2002 Eden Metro has been acting up. When i play channel 2 with my other bass hooked up to channel one, the switch keeps twerking over; indicator light switches between green and red when i push hard. At one point, it went over to channel one, and i had to push it really hard to get it back. Very uncool since it was in the middle of a show.. Have tried spraying it with electronic cleaner, works for a while, but starts acting up again. Anyone have experience with this? Is a replacement switch the only remedy? How does this switch work? I have some shows coming up, and i pretty much live on the north pole. Thanks in advance for input on the subject.
