When i press the tuner button on my fishman classic 4t and try to tune my guitar the letters won't light up to show that i'm tuning my guitar. the battery is brand new and it still works through a pa...is there anyway to fix the tuner itself? I have a new guitar with a new fishman 4t tuner but I dont have the instructions, I'm a rookie playin' and I dont know the way to use it. Do you have the instructions of this tuner? Can you send me?
