300B

The JJ 300B is very detailed and smooth with a huge sound stage. Customer feedback on these tubes has been extremely positive no matter what amp they are used in. We use them in our single ended parallel output JJ 322 Amp which is an amazing piece of gear.

**Builders: Keep yours eye peeled for the new JJ 300BH which is a 300B variant designed specifically for guitar amp applications. It's featured in the new JJ ONE Guitar Amp and will be available for individual sale shortly. We've been experimenting with this tube and it brings a whole new meaning to dynamics...
