12" G12C/S - 75 watts


If you are looking for a speaker with a classic American vibe, but need a smoother more soulful top end, look no further than the WGS G12C/S. This is based on our popular G12C, but with a smooth cone, felt dust cap, and just the right amount of edge treatment. This speaker works great in amps where you are going for that big American clean but just need it a little softer up top. With its touch-sensitive response and ability to take pedals extremely well, the G12C/S has become one of the most lauded in our American Vintage line.

Excellent Speakee

Installed in my 66 DR. Exactly what I was looking for. Really opened it up.

Freddie Franken
This Speaker in a Vero 20th Century Limited

Boutique, custom, hand-built 25w amp in Joliet IL. SOUNDS FANTASTIC and loud, lots of headroom. Love the speaker vibe. Used for jazz, straight-ahead jazz, archtop, and some blues. Give me enough full tone and enough twang on a strat. Great speaker! Not a hobbyist, pro player.

James Steffen
Awesome Speakers!

They Sound Great! Thank You!

Sounds like an American speaker!

This speaker is true to its description. There’s top end clarity without being difficult on the ears. Plenty of headroom when installed in a pretty clean 50w combo amp (Ampeg GVT52-112). Makes it easy to dial in Deluxe Reverb tones. WGS also shipped fast, and the speaker arrived in perfect condition. This purchase was a good deal, and I’d definitely buy from them again.

My Search Is Over!

I put a pair of these in my Twin Reverb after trying a couple of other brands, and I wish I had just got these first. I use a lot of pedals, and these do handle them very well just as described. They also sound great with distortion, which was the main problem with the other types I tried. They sound excellent right out of the box, even with no break-in. The spiky highs are gone, but still a beautiful American clean tone. If you use an American-voiced amp as a pedal platform, I highly recommend these. I'll probably get another pair for my JC-120.

"Ceramic's are kinda blowing my mind right now. I put a G12C in my 59 tweed Deluxe and it gave me more presence than I was getting with the Alnico. The amp was punchier, clearer and had some serious cutting action. I put them in my Ampeg Gemini 1's and they killed (in a good way). I think I'm done now for a while. If you want your small combos to have more headroom, cutting ability and some big machete attitude, The G12C's are the way to go."
