Hey i have a boss tu-3 chromatic tuner, i could probably have bought a new one for the price of all the batterie ive bought. At first i realised i needed to plug out the jack when i was done playing (it's my first pedal) so i thought it was just that. But it still drains batteries. I bought a brand new battery, played with the guitar with the tuner in for about 15 minutes, then plugged out the tuner. the next day the battery was dead.

I delivered the pedal to my local music shop where i bought it, the guy said that he put a new battery in the pedal and let it stay on for the entire night, and the next day it was still power left in it, so nothing was wrong. but i came home with a new battery now and the same thing happens.
Atm i can't afford paying for the pedal being repaired+ according to them nothing is wrong with it
So does anyone know a way i can find out myself what is wrong? and fix it?
And yes i am aware i can just buy a charger, but i don't want to have to depend on always having a charger for my pedal, that shouldnt be neccesary.

Solution: return the tuner for a peach. The batteries in my Polytune lasts months. Why don't you bring it back to the guy for more than 1 day and tell him to test it over a few days?

Just take it back, and have them exchange it for another one. I've never had a problem like that with any of my BOSS pedals.

The same thing happened to me with my BOSS MetalZone. I pulled the jacks out everytime and it dies after about less than week of playing. I never returned it becuase i got an adapter, but i think it's a defect some pedals have.

Is it simple to fix something like this with a pedal? i would like to try doing it myself, anyone that knows how to that can instruct me? :P
