I have a Tobias Growler 5 with active setup. I have replaced the input jack, as the original went bad, and replaced the 9-Volt battery connector becasue it was trashed. Now, my batteries die so fast that I usually only get one session out of the bass before having to replace them. Do any of you wiring gurus have any suggestions that I can try before taking it to a shop and having them look at it? I am willing to do this, but if there are a couple of suggestions that I can try, I would be grateful.
