Following the great reviews we received for the Gold 12", we realised there was also a need for a speaker that conveyed the Alnico mellowness of the original Blue, with the speed and response of a 10" driver.The G10 Gold is the ultimate 10" speaker, blending unmistakable Alnico class with a rich low-end, creamy mid-range and vintage chiming top-end. Springy, warm, revealing and highly expressive, it can be used singly or in pairs to add a classy sheen to any amp, or in a 4x10 configuration for higher volume depth, warmth and shimmer, with less of the boom associated with 4x12 cabinets.

The Liverpool 1275 is the classic British rock tone,inspired by tones from the 80’s. A complex, thick and vocal midrange cuts through the upper-register, while nice, full, lower-mid grunt completes the warm, gutsy, tight lows. The highs, while clear, open and articulate remain warm and ear pleasing.

12" seamed ribbed cone with a large ceramic magnet, the replacement for C12N.
Similar to the 12LC but with less output and a smoother yet balanced sound that retains headroom. Some nice compression is evident compared to the 12LC but not at the expense of headroom. Originally intended for studio or home use, many musicians claim it to be the closest to the original C12N from 4 and 5 decades ago.

The original G12M of the 1960s was Celestion's first guitar speaker to use a ceramic magnet and paved the way for high power guitar amplifiers. The G12M uses a medium weight magnet to produce a sound that is smooth and warm but bright enough to hold its own against any rock backline.Known simply these days as the 'Greenback', the G12M's fabled 'brown tone' is characterised by a warm, controlled low-end, a rich, vocal mid-range and a delicate, detailed top-end. Loaded into a 4x12 and driven hard, these speakers exude warm, crunchy chords and sweet searing single-notes

Headroom, clarity, balanced response, power...
These terms have become synonymous with a vintage American design that is known and sought the world over.  WGS now pays tribute to this classic with our WGS12L. However like all of our designs, we didn't set out to make a clone.  With this model we paid extra special attention to the details, producing a speaker that delivers that same even response without sounding sterile and lifeless.  Boasting a cast frame, 2.5" voice coil and a 200 watt rating, and clocking in at 18 pounds, this beast is loaded for bear.  As a welcome addition to the WGS fleet, this speaker is definitely our battleship.

Note from the boss: "We compared both the EVM 12L and the WGS 12L in an 806 cabinet and it was almost impossible to tell them apart. The WGS 12L is a great alternative to the original and we recommend it without reservation as a perfect replacement for the EVM 12L."

The Revolution 60 provides the most sought-after British tones with a touch-sensitive dynamic range that offers versatility, clarity, shimmering treble, and a formidable low end to the mid-range foundation.
WGS ET65 Upgrade - more low end and fuller sound due to a larger magnet !

The G12M Greenback is perhaps the definitive vintage Celestion ceramic magnet guitar speaker. Developed in the mid-sixties, it was quickly adopted by players like Hendrix, Clapton, Beck and Page, who typified the louder and more aggressive blues rock playing styles that came to characterize that era.The G12M-65 Creamback produces the familiar woody G12M tone, but handles greater power making it ideally suited for today's amps, when a vintage tone is desired. The increased power handling brings with it low end grunt complementing the warm and vocal mid range, crunchy upper- mids and sweet, refined highs.

It's hard to escape the sound of the G12H, just listen to any Hendrix recording and chances are you'll be hearing a whole raft of them powering the guitar out of the mix.

These faithful re-creations capture the unmistakeable mojo of late 60s rock guitar tones. Unsurpassed in a 4x12 for cranking out towering, huge power chords, the Heritage Series G12H (55) features the 55c/s 'bass' cone. This model is famous for its thick syrupy tones, with a deep growling back end, densely complex mid-range and a finely detailed top end.

Originating from the Green Beret and Invader 50 lineage, the Invader 65HV celebrates our tonal heritage with remarkable proficiency. While retaining the authentic rock and roll character that established its predecessors, we’ve expanded on its capabilities with more power handling and a vented 50 oz. magnet giving greater SPL and thermal relief.

These build attributes result in a wide-ranging, potent voicing suitable for whatever style of guitar inspires you. Expect a refined harmonic profile—offering midrange complexity, smooth top end shimmer and a formidable bass presence. This design maintains extraordinary sensitivity to playing dynamics responding with remarkable clarity to every nuance of your technique, whether delivering delicate passages or commanding rhythmic chunk. 

A worthy successor to the Vintage 10, the G10 Vintage is a 10" speaker with bags of attitude. Using powerful ceramic magnets and the same voice coil design as the Vintage 30, the G10 packs an impressive punch with its 60W power handling.With the fast response of a 10" but with the strong and creamy vocal tones of a 12", the G10 is the ideal choice to add depth to hollow- sounding amps, or for players who want to get humbucker-type girth from single-coils. Can be used singly to add vocal warmth to small valve combos, or in quartets for a weightier but still lively attack:

We recommend the GE 5751 as a replacement or upgrade for 12AX7/ECC83 tubes in the input stage of guitar amplifiers (V1 position). Whether your amp is low or high-gain, the GE 5751 provides a full, warm sound with clean bass. These tubes generate a high k2 content, making them ideal for those who prefer a rich sound.
However, the 5751 should not be used in cathode follower stages (CF) specifically designed for 12AX7/ECC83 tubes.

Superior medium-mu small signal twin triode with high transconductance. May be used instead of 12AX7/ECC83 in first gain stage of various amps for a more linear, vintage response.

• Originally designed for use in audio preamplifiers requiring low microphonics and good linearity, such as Fender "Tweed" Series
• Perfect replacement for any 6072/12AY7 type
• Relabeled Electro-Harmonix vacuum tubes are used by many OEMs in their amplifiers
