m not sure this is a problem they do run down batteries I would suggest you retrofit a 9VDC wall wort power supply to supliment the batteries for the show youll have to wire it in with a jack instalation or just put the 9vdc batt connector on the end wire it oposite and it will plug in instead of a battery . we are always installing new batteries for shows as soon as the show is over its dead ...
The batteries on my other guitars last for weeks of gigging and for months when the guitar is idle. I take your point about using a 9VDC power supply, I may have to resort to that. I am left wondering if there is a problem with my pre-amp or is this a feature of Yamaha pre-amps! If I'd known that, I wouldn't have bought the guitar in the first place.
do you have a tech sheet? does it list the current draw?
No information whatever with the pre-amp. And as I said, no help whatever from Yamaha customer service. Just wondering if I should source a replacement pre-amp or if this is normal for this type of pre.
if it works and it sounds good has plenty of gain I cant see anything being wrong with it that would cause exessive batt drain without it not working right ....
check the switch on the jack make sure it releases when you unplug it
it should not kill a batt if you are not using it
Thats what I thought too. So I now remove the battery every time I finish playing. I'll check the jack switch just in case. The other solution is to sell the guitar and get one (not a Yamaha) that works properly. Thanks for the advice.
Thanks for using JA if there aything else I can do please let me know Have a great day if I find anything useful Ill post it !!!
