I'd like to put a "Bobtavia" and a "Boutigue Bender" in the same Hammond enclosure. I run them both on batteries only and I'd like the octave first. My question is: how do I stop battery drain from the Bender? I realize just unplugging the Octave will turn the battery off for it but what about the second pedal? I also would like to keep it DC jack free (I like the vibe of having them the same way Hendrix had his pedals). I got the idea from the "Jimi in a Box" article. Thanks for any help.

You will persumably have a stomp switch to turn the Blender on & off, so this could be wired (3 pole switch, or 4 pole if you want an indicator, or 3 pole plus Millenium bypass) so the power to the Blender is off when it is bypassed.
Or I might be missing something.. I assume the circuits are the same polarity?
Don't forget you can get input jacks with more than one switch on them (PCB mounting).

Thanks Paul. I think I'm just going to bypass the jacks between pedals and put a SPST switch on the Benders battery wire. I'll have a seperate DPDT footswitch on either end of the pedal for each effect, and I'll just have to remember to turn the Benders battery off each time I'm done. Thanks

Are you planing on using one battery for each effect? Why not use one battery and feed both effect from that one? Plugg the guitar cable in and you've got power for them both. Unplugg it and there's no battery drain.
Or am I totaly missing something?

Using the bypass switch to power the fx as well as bypass will give you popping from the filter caps wont it ?

Couldn't you just use a stereo jack for the output as well? and just wire it up like the input for the octave, you would have to unplug both jacks but seems to make more sense than adding a switch you may forget t oturn off, to me at least.

there are two ways you could do it,

the first would be to use one battery, and use the input as the switching jack, with all the grounds hooked up together and all the hot lines coming from the same battery
this will drain the battery twice as quickly though (though you will go through as many batterys over time)

the second would be to use the jack switching on the output jack for the second battery
all this would mean is that you would have to take out the output jack as well as the input jack to switch off

Narcosynthesis, I never thought of using the output jack for the second battery! If it works, that would make the most sense as it would disconnect both as I unplug the pedal and I could use a single battery for each effect without having to worry about replacing one battery twice as much. Thanks
