Wow! When I searched the interwebs for a slo blo fuse I never imagined how impressed I would be with the ones I got from Amplifiedparts! Not only did these fuses fit perfectly in my 5f6a build, they added the shimmering sparkle high end my silver face twin reverb lacked! THANK YOU to amplified parts for helping me find my tone!
