Running 3 Boost Circuits on 9v

[quandar]

Would it be possible to chain together 3 boost circuits (such as the EH LPB2), and have them all connected under the same 9v from a battery/adapter (rather than 9v for each circuit) while not losing gain?

I'm a bit new to this whole pedal building realm, and I didn't see this question immediately under search, so I hope this hasn't been asked a bunch of times.

Thanks in advance.

it's perfectly possible and there are other threads on the same issue.

only thing to concider: you'll need 6 wires from the 9V adapterjack!
3 x power and 3 x ground. (1 to each board)

on top of that maybe 3 more wires from the power lug to 3 LEDS.

but it's possible.

you could wire the power and the ground of the adapter jack each to a tiny piece of perf or vero board and make the connections to the circuitboards and LEDS from this tiny "power and ground board". if you know what i mean.

you won't lose any gain if you use a boss adaptor, which is able to power about 6 to 8 effects.
3 boosters won't draw much current, so you'll have power to spare.

the real question might be...
why 3 boosters?
why not 3 different boosters if 3 boosters?

hope this helps!

One's entire pedalboard is essentially one big circuit powered by whatever you use (a single PSU or multiple units).  The visual divisions you see imposed by the boxes, jacks, connecting cables, etc., are all illusion.   The sooner one learns and accepts that, the better things will go for you.

Having said that, one of the things that individual pedals assume is that they will be the entire pedalboard.  In other words, because the manufacturer can have no assumptions about what else might be used in conjunction with that pedal, it is designed as if it will be the only pedal used.  One of the things that accompanies that assumption is, or might be, things like protection diodes to prevent misconnection of batteries or use of wrong polarity wallwarts, internal caps to smooth out external power a bit more, and so on.  Those sorts of things do not HAVE to be replicated for each circuit you happen to stuff into a chassis.  So, for instance, if I were to stick 6 different distortions in a big box, with one central power supply feeding them all, I do not need to prevent misconnection of the power 6 times, or smooth external power 6 times.  Once is enough to do that particular job.

I'm not sure why the need for three boosters in one pedal.  Two, I can understand (for overdriving one with the other), but given that what gets called a "booster" is usually intended to be clean, I'm not sure what advantage there is to having three redundant devices in the same package.  I might also point out that the current draw from many of the so-called clean boosters is generally modest enough that you probably could power them both from a single battery should the mood/requirement strike you.  Moving up to 3 boosters, with their associated status LEDs might start to push the envelope on battery-current consumption.  Just a thought.  Also, given that by your own admission you are a beginner, it might be wiser from the perspective of avoiding wiring and layout issues to stick with 2 instead of 3.  I certainly don't want to underestimate your building chops.  Just trying to maximize likelihood of success.
