12" G12C/S - 75 watts

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.

The search is over

When I was 16, I lost my gig in a band to another, older dude who had an SG and a BFDR. The sound he got out of that combination has been stuck in my head for 40 years!
I have a 1965 BFDR that I’ve tried every possible speaker known to be a “keeper” for the deluxe reverb and, until now, none of them has captured “that” sound. As soon as I installed the WGS 12 C/S, I started smiling and haven’t stopped since. If you’re looking for that vintage Fender clean that transitions to the RIGHT crunch and distortion in a BFDR (NOT an easy bill to fit!) and yet isn’t spiky at any volume but instead sounds like a well-broken-in Chicago Jensen but with a bass response that stays tight (again, a tough combination for any speaker to achieve in ANY amp, but especially in a deluxe reverb) this just might be your ticket. After years of searching and plenty of $ dropped down a hole, my search for the speaker that reproduces the sound in my head is finally over.

68 fender Twin Reverb.....the original

I had two dry rotten JBL's in my 68 Fender twin.... I replaced them with 2 12" G12C/S ....This was one of the best sounding speaker right out of the box....of course now that I have used it for a few years sounds even better after the break in period....I made a custom head cabinet and re tolexed an old cab to match the head, put the speakers in and what a happy.

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

"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."
