12" G12C - 75 watts

12" G12C - 75 watts


The G12C is our classic American workhorse. Boasting a 35 oz magnet, seamed cone, and a 1.5" voice coil, this speaker drips with vintage American tones. A punchy, dynamic low-end response coupled with a musically articulate top end gives the G12C plenty of muscle while keeping it touch-sensitive. The higher power handling means it will work equally well in lower-wattage combos and bigger 2x12 cabs. Ready for your favorite American cleans? This is your speaker.

Put this in my Fender Princeton RI and it sounds great.

Great bang for the busk with this speaker. Sounds great in my 65 Princeton RI.

Impressed so far

Bought a SS "Craigslist special" Fender Princeton Reverb just to use the cabinet, but liked it enough to pull the capacitors and fix it up. The Eminence stock speaker in it was pretty darn good, but I decided to see what adding a WGS would do. Even better. The WGS G12C is surprisingly mellow and "springy," which I value for Fender products (no ice-pick highs on this speaker). Frankly, I really have not had time to break it in, but it does not seem to matter (as would be the case, say, for a Celestion blue) as it sounded great from the get go. I need more time to assess, but I was really happy with the initial sonic profile.

Review of Chris Kline on 12" G12C - 75 watts

I've tried many very nice speakers in the 1x12 I use with a Fender style/Ceriatone amp that I built. Basically a blackface with tremolo @ 17w. By far the best sounding speaker with that amp has been the plain brown, unassuming looking G12C. It is tight and clean with just the right amount of warmth, there is zero harshness and no loss of articulation. It is really the perfect blackface Fender speaker, it just sounds right!

Review of Brad on 12" G12C - 75 watts

One of the best tone improvements I ever made. I like this speaker so much, I've switched all my cabs and combos over to G12C's in the past year. Totally transforms the sound of your amp.

"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."

By the age of 10, he was playing local events and talent contests near his hometown in Southern Indiana. By his mid-teens, Logan was digging further into the early blues players like Robert Johnson, Charley Patton, Junior Kimbrough, and Son House. At this time, he knew he wanted to pursue music professionally and in 2009, he moved to Nashville to study at Belmont University. During his time studying at Belmont, Ramp had the opportunity to grow into a more versatile musician, incorporating jazz and country styles, further influenced by greats such as Albert Lee, Brad Paisley, Vince Gill, Brent Mason, Wes Montgomery, Joe Pass, and Charlie Christian.
