Last week I purchased online a ESP LTD D-5 bass guitar. Excellent reviews overall for item (neckthrough body with ESP SB-5 Set pick ups and Vol / Bal w/ ESP ABQ3 3-Band Active EQ). Maybe is bad luck, but as I plugged it to my Amp Combo I found there was getting no output AT ALL - NOTHING (this was two days ago). I tested replacing the battery. Not worked. I plugged my old bass back (with active electronics as well) to check if it was an AMP/Line issue and the old bass worked as always. I put the original battery back. After couple of minutes I re-plugged the bass guitar and suddenly it worked. Today had the same issue (no output). I don't want to open the battery holder again (I would rather returned as the bass is yet under a 40 days return policy) as I could damage something loss the opportunity to return the bass guitar. I would like to know (this is my first bass purchase) if I am doing something wrong, if its a simple issue I am not paying attention to or if I should just should simply return the bass guitar. Thanks in advance.
