Stereo jack question

[knight_yyz]

Hey guys, I see that a stereo jack is recommended on the input of a pedal so that when you pull the cable the box is definitely off.  But if you have a chain of 8 pedals, is it necessary to have a stereo jack at the eighth pedal?  The first pedal probably has the stereo jack so wouldn't that accomplish the same thing?  
Or does it really matter if you have a bunch of patch cords.  I don't think people are pulling all the patch cords to shut off the pedal.  
I'll be adding a switch to my main power supply so I can shut off all the pedals when I am done playing.

The stereo jack is mainly used when you intend on installing a battery. If you don't intend on using batteries, then you can get away with not using stereo jacks.

That's what I thought.  Thanks

Yeah - this site really pretty much is made up of circuits where batteries are not required. The exceptions are the fuzz tones which use -9v (reverse polarity). Batteries make some sense in those pedals because they are not "power brick" compatible. But many of those pedals also come with "power inverters" that turn the polarity around (you will learn to recognize those, they usually have +9 going in and -9 going out to the main circuit - with am ICL7660s chip and two caps to do the power inversion)

But to answer your question - unplugging just one pedal won't affect any power going to other pedals. if they all use batteries you need to disconnect the cables to all the pedals.  If you use a power supply with just cables to each pedal nd no batteries, there is no need to disconnect any pedal.


Edit - changed "last" to "one"

I disagree. Unless you're one of those special TGP snowflakes who thinks he hears a discernible difference in toan using batteries there is no need anymore to use batteries in pedals. -9v? No problem whatsoever for all the good powersupplies. And for those who like to use daisychains nothing a simple chargepump can't fix.

I used to include battery snaps in all my builds until one I realized, why the hell am I doing this? I never EVER use batteries. It was just something I did because everybody was doing it.

[motterpaul]

No one said anything about "toan" - I said batteries are recommended so you don't have to worry about finding a special non-standard power supply because those pedals are not compatible with most power bricks (tho some bricks also have outputs that offer -9v compatible outputs as well, but not all).

Tho a battery is easier for a lot of people than using a power inverter, personally, I always include a power inverter, but the point was to alert the OP on what to look out for when it comes to using batteries - because not all circuits here that are -9v include power inverters. Then you pretty much need a battery or  special power supply.

Not really, what you need is an inverter daughter board which is way smaller than a battery and doesn`t need changing cos it wont run out of juice.

[rocket88]

paul, pretty much every circuit that uses -9V power that is posted on the main side does not include a charge pump. the charge pump is on a separate layout that you have make as a daughterboard, and some may not know that it's there. so, it may not be easier to use a battery, but people may not know there's an inverter to make.

there is some truth about batteries changing the tone of an old fuzz, but it's due to the amount of voltage going to the circuit. as you use a battery it loses voltage, and is inconsistent at supplying voltage. the easiest way to replicate this and use an inverter and power supply is to add a voltage starve pot.
