can 1 battery power 2 circuits efficiently

[scottosan]

For example, If I wanted to put a BSIAB II and an AMZ mini-booster in one enclosure, could I power bothe circuits "efficiently"?

Thanks in advance,

sure. just realize that your battery will run out faster, as both will be drawing current. i recommend the wall jack.

Yes.
 Will work fine...measure the [should be] nominal voltage drop when 'adding another', or current draw increase...battery life should be pretty good.

I tried Wall Warts a buncha times, always noticed noise increase, I don't use them...I'd like the convenience but the noise always bugged me.
 I see people put 9V jacks on the boxes all the time, I don't mean to be rude ... if you use a WW into 9V jack, instead of a battery, don't you notice increased humm or other noise?  
 I should note that I have a regulator on my EZ Vibe, running off a Wall Wart, and it's about noise free...don't know why, phaze 90 doesn't like a Wall Wart, can't remember which circuits I've tried WW's on, but probably more than 8 different ones.
 Next 's,,,which circuits work good with 'bare' Wall Warts?, and does a regulator decrease ripple or any other unwanted 'artifacts'?

Not counting hum issues, part of the "noise problem" with wall warts is that if your two pedals only draw 30mA of power and you power them with a 200mA wall wart, the supply voltage will go up because of the minimal current draw. This in turn will raise the noise floor of your circuits because now they might be running on 13V instead of 9V - and if the circuit is borderline noisy on 9V, it will certainly be noisy at 13 or 14V!

Hey!
i've the same ? for U....
i take the 2 pcb of the low and High freq modulator from GGG and i make a single pcb, with one ground and one  9+ imput.
D'U think that my pcb will work without noise?



i'm gonna do this efx next week.

thx!
