I also asked Nik. I was hoping to get some answers from real world players but thats cool. Here is his answer for anyone who is interested:

Richard
 
It's best to divide them -
 
OTS and S&M are 80s Dumble ODS.
 
HRM series are 90s.
 
 
The HRM main difference is that its got a post OD tonestack inside the amp for the OD channel.
 
Then, the master isnt shared between the channels. MV works for clean only, which makes it easier to preset volumes, perhaps, for live.
 
There are other feature differences as well, incl. actual Deep switch.
 
Sound wise -
 
The HRM is much gainier and tighter on the OD of all. You can definitely tweak this to match what you want.
 
The Bluesmaster has excellent cleans, but the OD isnt gainy but more articulate.
 
The OTS is perhaps the most typical "dumble tone" - dark, fat type. and the 80s are more organic and more open than the 90s.
 
The S&M is very open and brighter than above. Its more open/organic than even the OTS.
 
 
Hope this helps!
 
Thanks!

Nik

Thank you

Another dumbarse noob question.

Can anyone tell me the difference between:

The Overtone special, The Overtone S&M, Overtone HRM

Its a pity there is not a product description on the website.

Thanks again

I just reread my post. What I am meaning is that the clean sounds I have heard on youtube are very Jazzy sounds.

Thanks

Hello Everyone. I am considering getting a ceriatone and not sure what to get.

After spending a day looking at Youtube I think I have narrowed it down to 2. Either the Overtone or the DC30.

So I am after some advice.

1. My main goal is a really nice clean sound. (I have 3 Marshalls so I have overdrive covered . I guess a nice Fendery/Vox sound is my best description. Years ago I had a twin reissue (that was too loud) but it had a lovely clean sound.

I like the extra options the Overtone has but I have not heard any really clean tones as yet and I am concerned that it might not lend itself to awesome clean sounds.

2. I have a JCM900 2 x 12 Combo that I have never liked much and I am thinking I could pull the amp out of that and use it to house Ceriatone. Anyone tired this.

3. Lastly....Is it a major mod/extra to add reverb? or am I better off getting a decent pedal.

Thanks for your time.
