25 Jul The Big Speaker Shootout

In my belief, speakers are the most important part of your tone. They are not only devices which convert electric current into sound. All speakers have their unique voice, they all sound and feel different. Because of this, I have always thought about them as an instrument. A good speaker actually acts just like an instrument, reacting to your picking dynamics, creating feedback, co-operating with your amp and your guitar in a way that can yield very pleasing results - if you use them properly. A good speaker has this mojo which cannot be written down in words. :)

 Just in case you missed the terrific post about the history of Celestion by JaiminhoPagina, you can find it right here

Why am I telling this to you? Because it connects directly to this one. I think that post is worth a reading before digging into this one, as it sums up the history of celestion, and the speaker models, cones etc. over the time very well, which I think is very important before you listen to them and judge. And now let's get to the topic :P A long long time ago in a galaxy far away... there was a forum thread on thegearpage.net, started by Scumback Speakers, which contained amazing soundclips of different speakers. To be more specific, it is a comparison between original pre-rola celestions, new celestions, as well as several celestion clones, like Scumbacks. Unfortunately the links became dead, so the clips were unavailable for some time. Recently I contacted Scumback Speakers, and I asked them to update the links, so that the clips are once again available to everyone!

22 Jul Celestion Loudspeakers: From Blues to Greenies and beyond

Speakers are extremely important when we are talking about tone. They give the amp its "voice" and so, in order to get the right sound, you will need to use the right speaker. So, what should I get to achieve the tone I want? Well, now that's a tricky question. This article will be a (maybe not so) small post about the history of Celestion, as well as a brief description of each model they produced over the years. Of course, this won’t cover every one of them. I’ll simply feature the ones that I think are the most popular and most widely used models. Let’s start, shall we? Early years and the G12 AlNiCo Celestion started as a manufacturer of speakers for general use (radio, TV, etc.) back in the 1920s. In 1947, it was bought by British Rola and, one year later, production moved to Thames Ditton.

AlNiCo Blue 15w (as used by VOX)

It wasn’t until the 1950s that Celestion developed their first guitar dedicated speaker: the G12 AlNiCo T530 (a.k.a. “Blue”), basically a modified version of the CT3757 radio speaker. These first speakers went through quite a few changes (also appearing in different colours like silver, chrome and red - also with different codes) during the early years, but they remained with a low (in today’s standards) 15w (20w in latter versions) power handling and with both 8ohms and 15ohms options. It was used in Vox and early Marshall amps. With the 100db sensitivity, it was a very “loud” speaker. It was also bright, lively and had a more restrained bottom end. It’s probably more suited for Blues with clean or lightly crunchy tones. About Greenbacks Let’s start with a simple little thing. Most of you probably already know, but it’s worth to clarify this to the “newbies”, alright? (just joking! ;P)

G12M Greenback

The old Celestions from the late 60s and early 70s had a green plastic back cover and this is why they were nicknamed “Greenbacks” (no sh*t, Sherlock!), but “Greenback” does not refer to any specific model. It’s simply a “generic” name that was given to the speakers of this period, similar to how “Plexi” is a name to all the pre-1969 Marshalls. In other words, both the G12M and G12H can be called “Greenbacks”. Not only that, but also their many variations, such as the 55hz “bass” cones and etc. But I will explain everything in details shortly. The bottom line is: be careful when using the name “Greenback”.
