Made in England

Celestion’s production of the G12M Greenback 25W moved back to Ipswich, England. The first of the new English-made arrived in April of 2018. The G12M Greenback 25W were, in previous years, made/assembled in China. If you are looking for English craftsmanship in assembling the same speaker, this is for you.

Really made in UK?

This history, and the fact that the speaker magnet cover reads “Celestion International” leads some buyers to suspect that these were also made in China. However, the product photo (is not exact unit sent, but all our stock is like this) shows:
  1. It says “Made in UK” on the UPC sticker of the unopened manufacturer box.
  2. There is a thick manufacturer’s sticker on the side of the speaker’s back cover that says “MADE IN UK”.
  3. The speaker magnet cover reads, “This loudspeaker is the original Greenback specification”.

We also have a separate listing for a few remaining G12M Greenback 25W that were made in China.

Angus Young’s choice of guitar speaker

Famously played by Angus Young of AC/DC, Celestion’s specs for the Celestion G12M 25W Greenback 12 inch Guitar speaker boast:

The G12M Greenback has evolved over the decades but still retains its essential, sought- after tone.Angus Young has been a Greenback devotee since the early days of AC/DC. This model is voiced with additional broad mid-range attack and restrained top-end to give a forward, punchy attitude to chords and a searing lead tone without fizz. With its well-controlled low end it can be used singly in low-powered amps, or in multiples for high-power rock heads. It’s an ideal guitar speaker to bring drive and definition to modern high gain amps.

Celestion G12M GREENBACK 25W 75hz 16 Ohm

The following is the story behind this speaker, which is among the most classic of the classic rock guitar speakers. I do not sell in Germany, and I cannot link to any site that does, so this author will remain anonymous – but he is not my competitor, so here is the info:
The legendary british Blues & Rock sound of the 60s & 70s.
Way back in the 1960s, Celestion released a version of the popular G12 guitar loudspeaker called the G12M. These days nicknamed the Greenback, with its medium weight magnet this speaker had a tone that was silky smooth and warm, while still retaining the brightness and punch necessary to cut through the rest of the band. The Greenback was also a highly articulate speaker, perfect for the pioneering lead guitarists of the time. A classic had been born.
Over subsequent years, the Greenback has evolved and remains popular with guitarists and amp manufacturers to this day. As the speaker developed, though, its tonal characteristics moved away from those of the original 60s model.
Adhering precisely to the design notes and specifications for the original speaker, re-discovered during our recent factory move, and using exactly the same materials and construction techniques, Celestion has recreated the classic 1960s G12M for a new generation of rock and blues guitarists.

Flexible Fulfillment:  We have a variety of shipping methods for fulfilling your order.  We may use the most efficient method for your case - and pass along our savings to you! Contact us for discounts on larger orders.

Delivery:
1. The guitar speaker can only be shipped to your shipping address specified in the eBay system. So verify that before you order.
2. Look for your tracking number in the email from us that will confirm shipment.
3. Watch for your speaker(s).  If you ordered more than one speaker, look for a regular or recycled brown cardboard box.  If you ordered one it will likely arrive in a white poly mailer bag.

4. Once you open that cardboard box, you sift through any packing material. Under it (or the poly mailer bag), you will discover the manufacturer's (OEM) box. Inside the manufacturer's box is/are the guitar speaker(s).  

Buyer's Delivery Info. / Address

Since free shipping does not include Shipping Insurance or Signature Service, the seller will have no recourse to pursue with UPS should you fail to provide a secure, private, and valid shipping address within the eBay system before you make your purchase.  Contact us before purchasing to request signature service for UPS Ground if you are concerned about the safety and security of your specified private delivery location, or if your purchase total exceeds $750 US. 

We reserve the right cancel orders with delivery address information that appear to be:
1. International - shipping outside the contiguous domestic United States, unless shipped via eBay Global (now also called International) Shipping Program (this requires a 10-digit phone number). While we've opted into this program you'll need to contact eBay for questions or support. International buyers must be proficient in business English and will be notified by us when the package is delivered to the eBay Global Shipping Program's domestic United States address, which completes our end of the shipping process, and our responsibilities in the transaction.  eBay ships it internationally from there.  eBay will not ship the item internationally if it arrives to them in a damaged box.  These boxes will show significant damage before the speakers themselves will become damaged.  So if you receive it damaged, it was damaged during international shipping.  The international buyer agrees to contact eBay exclusively regarding any such international shipping costs or returns since this seller does not support or offer international shipping.
2. Invalid - Our shipping software alerts us if the address doesn't really exist or is not verified. Buyers mistype, omit, get overly creative, specific, or forget to update or select their preferred delivery address.
3.Un-Insured and over $750.

Exclusions

Guitar Tone

Guitar Tone Samples

Our aim is to ensure that the tone of our guitar speakers CAN match the tone expected by the guitar community. Celestion and other manufacturers provide guitar tone samples for you to listen to, specs, and sometimes videos for you to review before you purchase. Typically, you begin your hunt for guitar tone samples on any guitar speaker's specifications page (see link above).

Guitar Tone Skills

Any buyer who does not already know this product takes responsibility for: Finding, sampling, and recreating the tone they seek. This guitar speaker is one of many important building blocks of your guitar tone (sold separately): Including your (1) guitar playing ability, (2) amp, (3) guitar (4) pedals/effects, etc. This guitar speaker should give you the analog space that you need to let your true guitar tone shine. It will not make you play as well as the guitarists performing the guitar tone samples. Seriously, no bad feedback, returns, or issues in eBay over tone issues.

Replacement Guitar Speakers

More modern and higher quality speakers may broadcast any imperfections in your tone chain that the older speakers you are replacing did not. Have your entire rig serviced before your purchase so that you only hear more of the good things in your tone chain. 

Electric Guitar Tone

Celestion's website provides information on how to break in a guitar speaker. This should be done before using any guitar speaker. This ensures that the speaker provides true tone and proper function over time.
