I have a 12" Eminence Cannabis Rex in my OTS 1x12 combo and it rocks!! I love the tone the speaker and amp have together

Santana uses Altec 817 Alnico. I think the closest thing would be something from Weber. They don't sound like the 65watt celestion.

Just to add...The gold is so much warmer and creamier than my experience with the celestion blue.

Martin Lewis raves about the Golds with the Fuchs ODS.

My overtone is the most versatile amp I own as the cleans are truly BF fender only better.  Better than any of the cleans I have heard on youtube and these forums.

The OD is so silky smooth it made such an improvement over the G12-65 which I though was just OK

I will do some clips as I think people are missing out on the massive tonal improvement
 of this speaker with the Overtone.   

I have just gotten my OTS, (regular version, Gabkits combo cabinet, playing a Strat) and have tried :

A Celestion C90 - sounded too middy with my Lone Star but surprisingly was not bad in the OTS,

A Weber Ceramic California - handled everthing but was a little sterile sounding

A Jensen C12K - I had high hopes for this but it ended up being too hot in the midrange

A JBL D120F - so far the best sounding speaker in that cab, but the highs are a bit piercing and the midrange is still not quite tamed

In general, I'm looking for a speaker that is scooped enough in the midrange to overcome the midrange spike I'm either getting from the cab or the amp. I would like to be able to use the "deep" (mid-boost) switch because some of the body I get from using it sounds really good, but so far it's been unuseable with the Strat, a little too woofy.

I have looked at several response curves and noticed that the Jensen P12N has a pronounced notch in the midrange of its response curve. Before I drop $200 on yet another speaker, has anyone tried one of these out with their OTS?

Re: Marinblues:

Seeing as how you have quite a lot of clips up on YouTube, and the tone is most excellent, I believe you may have a handle on it. Of course, the other players have their points of view (and hearing) which makes it a very personal thing.

I have a 2x12 Cabinet with a Greenback and a GT-65 in it. This will probably be a good starting point I believe. Of course, my amp is still 3-5 weeks out according to Nik (a couple of days ago). This has been the longest 3½ weeks of my life so far!

Thanks for the input.

Thanks JohnE;
I'm seriously considering an Eminence Wizard, by the way. I emailed Nik and he suggested changing the cap on the mid-boost (aka "deep" on the stock OTS) from 330 pF to 270 pF to make it a little less predominant in the mid range, to boost it, but not as much so to speak. I will definitely check the Matt Schofield settings as well. Thank you for your help.

Just for the hell of it, while waiting for some Eminence speakers to try, I put a Weber Ceramic Blue Dog I had sitting around in the 112 combo cabinet I'm using with the OTS. To my surprise, it sounded great in there. Can get very nice Knoplfer-esque sounds in the clean channel, and you can nail the classic British OD tone (think the opening chords of "You Really Got Me" by the Kinks). I'm not what I'd call a rocker, more into blues and jazz blues, so I might not keep that speaker in there permanently, but I thought that I'd report my findings to add to the general knowledge pool.

Celestion G12-65, I have two vintage ones in a semi open backed solid pine 2x12 and the tone is unreal, Robben Ford/Carlton tone no kidding.

Before that I had Weber Silver Bells, but the difference after changing to the G12-65's was astounding. They really take this amp from nice tube tone to undeniable 'D*mble" territory.
