battery change

Postby nuthatchwinters » Fri Nov 10, 2017 9:08 am

hello all. just curious as to what some of the other guys experience has been with how frequently you have to change the 9 volt with the buffer/pre amp and OBEL. I've changed mine twice in the past week and just was curious if this is common. I do play a lot, at least a couple hours a day and sometime as much as 5 or 6 hours a day on the weekend so its definitely been in use an awful lot. thanks for any input.

Doesn't sound right to me. If you're wired properly, AND you unplug your guitar after each use you should get months out of a battery. Have guitars that have gone nearly a year with nightly home use which would mean well over 100 hours of use.

Yeah- if it's wired right the only time the battery is in the circuit is when you have a plug in the output (not the OBEL) jack. That's why the output jack is a three-connection jack- not the normal two-connection. The third connection makes the battery circuit complete. Check and see if there are three wires going to BOTH of the jacks in the control cavity.

well just to update, turns out to be a bad tube in the amp and no battery or wiring problem. had been playing and was losing volume and the sound was off and automatically just assume its a problem with the guitar having just had it modded and just waiting for something to go wrong with it (guitar) but everything seems to be good. just have to replace a tube or maybe 2.

I've really come to hate that design of relying on the output jack for the battery circuit. I'm going to modify my guitar to have a battery and buffer on/off. Anyone have a wiring diagram they'd care to share? :lol:

Seems like all you'd have to do is add a switch in the battery/buffer loop? Wasn't there a thread a few months (or more?) ago about using a push/pull pot for that purpose? Do a search for buffer switch push pull and you'll find some.
