How to use 'Sag' controls on pedal power supplies

The perfect power supply for pedals? In an ideal world, a battery.
The Sag control on power supplies... what's it do? What's it for? What pedals sound good when you limit voltage?

When the first note of that fuzz hit, my soul stirred.

That Pantheon overdrive sounded really good indeed!

Great to have you back Brian, you are a valuable resource for a lot of people. Cheers

I don't want to alarm you, but it looks like a stormtrooper is trying to get the drop on you. Check behind the Fender amp.


We're concerned about your safety.

This is a great demonstration of what a dying pedal starving for more power sounds like. I have inadvertently unplugged a pedal that has an old battery in it and wondered what happened. This is helpful in that respect. I currently have my OCD and Dark Matter sharing a spot on my Pedal Power 2 Plus so I can have more pedals on my board. I can't do this wiith some of my pedals because they require full draw to work. I really like the fact Wampler has a safety feature that will keep the show going if there is a power issue. Bravo! -Big Papa

The Tube Screamer sounded really nice with a bit of sag!

[Briansgate]

Awesome, I have that power supply, and this was a great demo for me. Glad to see you back, Brian!

I was just testing the SAG feature on my Zvex Box of Rock last night, but I didn’t realize you could control the voltage with the front knob;
Your video couldn’t have come at a better time.
Thanks Brian! And Happy New Year

hey brian! just wanted to let you know [if you have the time to see the comments] that you influenced my decision to buy my first telecaster! its a 2019 Squire Classic Vibe 50's tele. butterscotch w/ black guard! ive had it for a month now and ive swapped out the 8 screw guard for a 5 screw black guard and ive added wilkinson compensated brass saddles. i never knew id like a tele this much, its fantastic!

i know you dont really talk about your tele all that much, but i figured if youre playing a tele all the time that they must be really good. so im glad i picked one up! and thank you for all the great vids you do!

The draw from using a battery I find is different as well, where the SAG gives a consistent lower voltage. Like the battery gives more and less current based on how hard you play(dynamics, what a concept!). I've noticed this in pedals that were designed for battery, like old fuzz circuits and designers that love battery. Most if not all Wampler pedals have acted and sounded "better" to me with a consistent voltage, are probably designed this way. Great Vid Brian!

Just 2 days ago I was looking for videos to understand this SAG feature as I set up my pedal board - awesome video, super helpful, great timing!!

[Gatecreeper]

Amazing video, I have this power supply and can't thank you enough for the in depth information about this feature. Hats off my man!

[braddietzmusic]

I’m not saying I know everything about everything Guitar-related. Surely I don’t. But... voltage sag is something I know absolutely nothing about, nor have I seen anyone get into. Thanks for the video. It’s a very interesting topic. Thanks!

[liamtahaney]

I just got my first pedal of yours...the mini ego. I love it. Thank you

[BandHouseStudios]

Brian, great playing and great video, this video is a fantastic demonstration of the SAG feature and how it affects the sound of different pedals.

[bofa]

I have that power supply and had no idea what sag meant. Thanks!

[michellowe]

Happy New Year & welcome back, Brian!
I could never figure out why you would want to deliberately voltage-starve a pedal. Your video makes perfect sense. Thanks and I’m looking forward to part deux.

[orryfishburne]

I’m loving your new approach to your videos

[johnroberts]

Excellent Video, Thank you 👍👍👍.
I have the Pedal Power 2, The Sag feature is Brilliant for Fuzz Pedals.
Take care ♥️👍

That's a Great analogy, I've not considered this!! Thanks for sharing brother! Be Well Brian!
