not for blackstar fly3 mini amp
Denis J.—January 24, 2025✓ Verified purchase
this thing is great cause it has so many settings and adapters that you can use on multiple devices. unfortunately it will not work with my blackstar mini amp. the blackstar requires a 6.5 volts 1.5amp power supply to work properly. this power supply has a 6 volt and a 7.5 volt setting but no 6.5 volts. also the amps for the blackstar needs a 1.5 amps and this power supply only provides 1amp. so this is what blackstar fly3 needs 6.5V/1.5amps. this adapter 6V/1amp. not enough juice and the next setting at 7.5 volts too high. anyway i found other uses for this. it works on my fender mini twin with its 9V setting and on my yamaha keyboard which also has a 9V requirement.
