JP15 battery drainage and possible improvements by EBMM

[lucar]

<div class="bbWrapper">Hi,<br /> <br /> I practice, or try to, <img src="https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f642.png" class="smilie smilie--emoji" loading="lazy" width="64" height="64" alt=":)" title="Smile :)" data-smilie="1"data-shortname=":)" /> 3 times a day.<br /> Plugging and unplugging the jack is a little worrisome for the connection... I know EBMM are quality guitars but...<br /> wrt the battery life I think it&#039;d be cool to have a small switch somewhere...maybe next to the jack inputs so that when I know I have a session with some acoustic sound I can just leave it ON. Usually it would be on the off position.<br /> <br /> Suggestions? Tricks? Ideas?<br /> <br /> Thank you you great people at the EBMM forum!</div>

<div class="bbWrapper">Hi there!<br /> Well...that&#039;s a modification that can be easily done by anyone who can drill a small hole, put a microswitch and solder a couple of wires. <img src="https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f642.png" class="smilie smilie--emoji" loading="lazy" width="64" height="64" alt=":)" title="Smile :)" data-smilie="1"data-shortname=":)" /><br /> <br /> But....why disconnect and connect a guitar cable should be an issue?</div>

<div class="bbWrapper">I have an old Telecaster (67) and over the years the jack holder inside got quite loose. I had to open it bend it.. not happy with that I had to go buy a new one and change it, get the soldering iron out, etc. I guess I&#039;m just cautious...<br /> <br /> BTW I&#039;ve looked over the JP15 diagram again and it looks like the battery is also used for the the magnetic pickups.<br /> Q: is it used ONLY when using the extra boost or all the time?<br /> <br /> Thanks guys</div>

<div class="bbWrapper">I&#039;d imagine all the time. The buffer is necessary for the piezo pickups, both on their own and to blend with the magnetic pickups.<br /> <br /> The mono output blends both pickups, so it&#039;s used there. And the stereo output has separate signals for the piezo and mags, but it&#039;s necessary there for the piezo.<br /> <br /> To the original question- you really shouldn&#039;t be worried about a loose output jack. These things are rated for zillions of cycles, and are relatively easy to replace should they wear out.</div>
