## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    Not the optimal solution...
  

*by J***D on Reviewed in the United States on July 24, 2019*

Well-built unit by Radial but what isn’t stated in the description is that the incoming (center negative) DC current must be at 400 ma which is often not produced with most power supplies. I ended up not using this as I later found out that my BOSS tuner provides a very good signal buffer at the front end of my pedal chain and I also found a power supply (CIOKS DC-10) that can directly power the 15V center positive Tonebone Pre-Z.

### ⭐⭐⭐⭐⭐ 







  
  
    and really glad I did
  

*by P***4 on Reviewed in the United States on March 28, 2016*

What a huge difference this made in clarity. Bought this buffer on a whim, and really glad I did.I don't use the 15V feature this buffer has, but very handy if your using pedals requiring that kind of power.I just use it as a buffer and its great, literally sounds like your plugged in straight to the amp.

### ⭐⭐⭐⭐⭐ 







  
  
    Great Product!
  

*by G***S on Reviewed in the United States on March 5, 2015*

Aside from the product arriving late(due to ice and snow; no big deal) I absolutely live this! I use a TriMode from Radial. Knowing that, my PedalPower 2 won't power it so I'm having to "wall wart" it. I did not want to buy a different power supply to accommodate it. Then I saw this & it solved all the issues. Great Product!
