As well as being the bassist in my current band, I am also the go to 'tech-guy'. Of recent times (i.ee now we are getting a few gigs), it has occured to me that I should not be the only one with a tuner. My question to all of you electronics wizards is this; How would I go about making a small pedal with an input for the bass and an output for the amp and for the tuner, that when the switch is pressed, the output to the amp is muted and goes to the tuner? Really, I want the same system that is in a pedal tuner like my Boss TU-2, but is DIY and affordable. Any ideas?
