Thread: Low battery indicator

    Low battery indicator

    Why is there no low battery indicator light on guitars with powered pickup systems?
    I have two models (JP13 and Cutlass) and that would be a huge benefit at what would seem a relatively small addition.

    It seems like a good idea, but I would assume that there would have to be a circuit to determine when the battery gets to or below a certain % of life, and it could just light an LED that could be seen thru the rear trem panel.

    Such a system would require the preamp be powered at at all times, or else there would be no way for the LED to turn on when the battery was low.

    The Parker Fly I used to own had a LED on the back panel. I lit up shortly when you plugged in the jack cable, then shut off. If the light stayed on, the battery was running low.

    I don't know if a similiar system could be retrofitted. In the end, the JP's and Majestys are made for John Petrucci, and I imagine his tech either switches the batteries or checks them every night, so JP doesn't need a battery indicator.

    I think this would be a great idea, if it were possible. My Rode capacitor mic also has a light which comes on momentarily when it is plugged in. If the battery is low, the light stays on, if not, it goes out. Yes, the guitars are made for John Petrucci, but he will of course appreciate the vast majority of normal mortals don't have their own techs!

    It doesnt matter how great EBMM guitars are folk seem to constantly want more from them imo anyway.

    Customer feedback does help shape future designs. Of my 4 EBMM guitars, none of them are perfect, there are always things that could be improved.

    Good point but customer feedback will do nothing on Sig models at all. Whatever the Artist wants is what we get.

    I never said anything about asking or wanting EBMM to do something like this. I had thought more along the lines of something someone could do on there own with the right knowledge and the right know how. TBone brings up a good point, but there are always other ways. I personally don't know enough about the electronics, whether it be JP's or Silo's.

    I think we see continuous improvement over the entire MM line. They do listen to feedback and implement good ideas.

    I appreciate the responses, but for those who think it’s difficult or has to be on all the time, I used to have a Breedlove acoustic that did the very thing I’m suggesting...and I guarantee it was not always on. It was only active when the cable was plugged in, just like I understand the powered circuits n the MM guitars are only using battery life when the 1/4” cable is plugged in. Just sayin...

    Acoustics that have an onboard preamp usually use modular preamps designed by a third party, such as Fishman, who makes everything in large quantities overseas. The preamps usually have multiple LEDs that say things, and are quite a bit more advanced circuitwise than the active preamps in EBMM guitars.

    Adding an LED that turns on when the guitar is plugged in and the battery is low would definitely add to the complexity of the circuit, and when this involves a lot of hand wiring, that would significantly add to the cost.

    Then there's the question of where to put the LED. Except for the LP models, the only exterior sign of the active preamp is the battery box. They'd have to figure out some way to stick an LED on that battery box, or they would need to make another hole somewhere for the LED to show.
