  • Good alternative for NOS

    I use these for my 5f6a Bassman. It sounds great. Just as good as the other current production.

  • Solid Upgrade!

    This really helped tame the overdrive on my Blackstar HT Studio 20. Highly recommended to reduce gain down from a 12ax7. Also, seems solidly built and I've never heard anything bad about JJs
