## Customer Reviews

### ⭐⭐⭐⭐⭐ Blackstar Power Supply works!
*by S***N on January 15, 2026*

This product is working as advertised.

### ⭐⭐⭐⭐⭐ The value and quality
*by R***R on October 14, 2025*

Perfect fit for my amp

### ⭐⭐⭐⭐⭐ Small issue in the beginning, the seller fully corrected the issue with great customer service!
*by G***R on May 11, 2019*

Update!!! This seller has excellent customer service. I told them about my issue, they contacted me the next day, and in less than a week they had sent me a fully functioning replacement FREE OF CHARGE NO HASSLE. The new cord works perfectly and I suspect that the bad cord (read original review below) was a rare defect, possibly damaged during shipping or maybe even in the factory. I say rare defect because I have had tons of these cords in the past and never had any issues. Aside from the very minor inconvenience, I am EXTREMELY pleased with this purchase and the customer service. [So when I initially plugged it in to the amp, the adapter didn't work. I wiggled the cord from the wall to the power block and it would turn on and off. That cord has a short in it, brand new. So I had an extra cord from an old laptop, and the power block works fine and without any hum... PROS: the adapter works well CONS: the cord from the wall WAS FUBAR upon arrival.]
