Stomp box power plug

[Ike Zimbel]

Can someone give me the spec or a p/n for the standard stomp box 9 volt power plug / jack? I'm building an active DI for a client and he wants to power it with his pedals. I know there are many different socket and pin sizes... He sent me a link to the power supply, the Boss PSA-120s, but of course the literature does not include the jack dimensions.
Thanks!

The typical DC barrel connector diameter is 2.1mm.

Like Bo said the standard for 9V DC pedals is 2.1mm DC jack.

the few pedals that use 9VAC use the 2.5mm size.

your PSU is 9VDC so this is the one I use for my builds:

you have a lot of choices here:

Always worth a reminder that for guitar fx use the connection is usually Centre Negative.
And using switched connections to take an internal battery (typ. 9V PP3) out of the circuit when using external DC source.

Thanks for all of the replies, guys. Much appreciated. I think I've found what I need at Digi-Key.
There will be no internal battery, so I don't need the switching jack.
