Hi , I bought an ibanez tcm50 vbs today I love it can't fault it apart from there is a problem with the tuner . The tuner works when you plug it in to the amp but when you don't it should work by using the power off the battery. It doesn't seem to be doing that though and I've changed the battery 3 times . And I really don't know what to do , please can you help . Thanks james
you have to remove the INPUT cable in order to prolong your battery life.
this should also be figured out in your manual.

in case you didn't understand my little wink:
Its not because its running out of power it won't work with the three batteries I tryed
