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 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.

The ET10 is the 10” version of one of our most popular speakers: the ET65. The ET10 boasts a tone reminiscent of its 12” counterpart, but with a bit more of a pronounced midrange.

Top it off with a smooth but articulate top end, and you have one of the most highly anticipated ten inch speakers to date.

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.

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
