    Yesterday I installed a second battery in my Ibanez Ergodyne EDB 605, wired in series for doubling the voltage. The first thing I noticed is that everything works fine, nothing was harmed. I noticed a slight improvement in clarity and punch, but nothing spectacular. Has anyone else ever done like this, especially to cheap electronics?

    I've done it a couple of times to give extra db headroom.

    Not all preamps support it. I have an Aguilar OBP-3 in my Modulus Flea bass, and it could get by with 9v but it's definitely got more kick with 18v.

    My warwick thumb 5 also has an OBP-3 preamp, as well as active EMG pickups. In this case, I found I needed to go to 18v otherwise I was getting some distortion at high volume settings with 9v.

    I don't think that the EQB-III electronics (propably a MightyMite product) "support" 18V use. I just wanted to find out what it does for me, eventhough I knew that I was exceeding the specified voltage. Yesterday I recorded some takes in the studio, and the modification didn't seem to improve things much. Raising the pickups had a more noticable effect on the sound, but nothing can really compensate for the very transparent (in a negative way) and lifeless sound of my very "special" Ergodyne. I guess it somehow slipped through quality control, because another one which I played sounded much more defined. Unfortunately I didn't notice that as I bought it, I was just amazed by it's smooth feel (compared to the Yamaha RBX I had owned before)...:rolleyes:
