But the ZGP shuts off. Protection mode?** A: I had something similar trying to isolate an HX Stomp. I just reversed the isolation direction ... I used the ZGP on the pedals OTHER than the HX Stomp and it was fine, did the job (prevented ground noise from the HX Stomp leaking into other pedals). **Q: Does it come with a DC power cord or only the device?** A: It comes with one DC cable. **Q: so, it looks like you can use a 1amp supply even though they rate it at 800ma?** A: The MAX you power supply is rated is 1amp, but will only deliver what is needed, up to 1 amp. Per the specs, the zgp will only pass 800ma to equipment. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked for me *by S***T on January 2, 2024* I have a bunch of analog pedals, some with charge pumps, and one digital delay, which is a BOSS DD-500. Having the DD-500 daisy chained introduced plenty of digital whine noise. This device, connected just to the DD-500 got rid of the noise in a jiffy, making the need for an expensive power supply like Cioks or Voodoo Labs moot.If I add more digital pedals to a pedal board for live performances or something, I might use more of these or an expensive unit... But just for one digital pedal or in the studio where I'm hooking things up and shifting them around daily, this does the job perfectly and I'll stick to regular wall warts with daisy chains and these on digital pedals.Basically, at home and in the studio, I don't use pedal boards per-se... I just get like a black, $5 food tray and put my pedals on that. No velcro etc. Easily rearranged, keeps things relatively tidy, and I can move the tray from place to place NP.I may buy a second one for that occasional need.Going forward, I vote for manufacturers of digital pedals to ALL include power filtering in their problematic pedals so that we don't need these big, dumb power supplies. Add some non-sacrificial fuses or something too. ### ⭐ It worked, but then only lasted for about a month *by T***T on June 17, 2024* I got this for a noisy pedal and it worked, taking out almost all the noise, and I was happy with it until today, when it just cut out. After it stopped working, if I unplug it and then replug it, it will work again for a few seconds and then it loses power and the LED goes off. Frustrating that it is not returnable. I guess it is poorly made so I recommend buying something that is higher quality. ### ⭐⭐⭐⭐⭐ Works as should, Isolated Power source *by J***R on July 13, 2024* Felt compelled to write a review since I’ve seen so many negative on here. This thing is awesome! Purchased a Walrus Audio Canvas Tuner recently, plugged it in and there was a nasty hum in my signal chain. Come to find out that the pedal needs ISOLATED power. (I currently run a tourtek rechargeable powered pedalboard, plenty of power but no isolated dc outputs.)Enter the ZGP! Plugged it in, mounted under my pedalboard with a small Velcro strip and done! Pedal is quiet now with no hum or interference noise. Purchased a second unit to have on hand as back-up! ## Frequently Bought Together - JOYO ZGP Guitar Pedal Power Noise Blocker Support DC 9V Max 800mA Output and Power Supply Isolation (JP-06) - JOYO DC 9V Guitar Pedal Power Supply (800mA -1A) AC Wall Charger Adapter with 4 Way Daisy Chain Pedal Cables (8.8 FT), Compatible for Most Effect Pedals (Tip Negative) - JOYO American Sound Amp Simulator Pedal of Fd 57 Deluxe Amplifier from Clean to Overdrive Sound for Electric Guitar Effect - Bypass (JF-14) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/228618382-noise-blocker](https://www.desertcart.at/products/228618382-noise-blocker) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-05-03*
