Amazing for that Brownface tone

Amazing for that Brownface tone

Bought this speaker on CJ's recommendation to go with a 6G3 build I acquired, and yeah this speaker really amazes me. At lower volumes, I get a lovely chime and sparkle through both the normal and bright channels.

The beauty of this speaker comes through when I have the volume cranked, which is what this kind of circuit was designed for. At higher volumes, even though the tubes start to compress the overdrive, you get a great punchy tone and of course that midrange bark and crunch you hear that reminds us of Nugent, Gibbons etc.

Amazing work, and thank you to the Weber team!

This speaker somehow bridges the gap between late 50’s American tweed and early 60’s British type tones. I have the 50 watt version with the screen type dust cover in a Fender tweed deluxe. This is the only speaker I’ve heard that cuts through in a band, holds together beautifully when pushed while allowing your Fender to sound like a Fender with a British accent. An amazing and unique speaker. The team at Weber went above and beyond to get this speaker right for me. Amazing customer service. Thanks again, KT

Music to my ears!

I have a Pro Junior. I love my Pro Junior, but my drummer suggested it needed a little help sounding "bigger", so I built an extension cab and loaded it with the 12F150B. I am loving it! All of the good stuff built into the Pro Junior lives on, but some of the annoying "rough edges" have been smoothed out and warmed up. Really amazing what this speaker upgrade has done for my sound.
