    Can anyone say anything positive?

    Out of 22 effects, I may find a workable tone out of 2 or 3 effects.

    The only experience I have with COSM is in my JS-10. I use it mainly for learning songs or very low level volume playing. I have also used it to record guitar with electronic drums (also Roland) and it did an adequate job of that, at least to get some ideas recorded. In those settings, it's fine, but I don't think I would want to gig with it.
    And as you related in your post -- I don't know how many amp models are on this thing (best guess would be 30 without checking), but I find I use 2 for what I do with it.

    I bought a DD-20 years ago when they were new and was intrigued by the prospect of COSM modeling technology. That said, the unit was a huge disappointment for me and would not hang in a live band situation. I remember only liking one or two models, and they would disappear in a live band mix. I am sure there are people out there who have created good music with the DD-20, I just couldn’t get it to work for me. Bottom line, if it works for you it doesn’t matter what I think anyway. Music is about experimenting, right? Good luck with the unit.

    I'm using a boss gt6 in effects loop of my dsl head and straight into front of my 4100(I m using a bbe362 in fx loop of that), and my sound is pure 80s tube metal. I'm using the fender twin reverb preamp setting with Metalzone distortion on gt6. Been happy with the metal sounds I've gotten from the gt6 since I bought it new in 2001

    Well, as you can see I use that exact pedal as part of a 4CM pedalboard.
    I got it mint, boxed for £90.
    It is a good fun pedal that has limitations (like all pedals).
    And I am no aficionado of recreated pedal tones.
    If I like it I don't sweat the minute (or glaring) differences a cork sniffer would shoot himself over.
    Hell, I even use a ZOOM for all my TBEs!

    The presets I use are:
    1. Blues Driver. I had a BD-2 when I got the OD-20 and couldn't tell the difference, so I sold the BD-2.
    2. Almost Nothing! The OD-20 has AMP CTRL, so my second preset is the OD channel of my VS65R (AC/DC gain levels with a bit of optional OD-1).
    3. Guv'nor. For a higher gain Marshally tone.
    4. One of the Fuzzes. It changes with time. All 3 sound good to me.

    The MT-2 on the OD-20 is good, but cannot be dialled in the same as an actual MT-2. Never gets quite as throaty.
    Hence, I have a separate loop for a real MT-2, bypassing the preamp.
    The other overdrives and distortions are OK.
    I like OD-1&2. But they are so similar to T-Scream that I don't bother with it.
    P-RAT is a bit harsh for me.
    HM-2 is ridiculous!
    The Drive knob does offer more gain than original pedals in the Turbo zone (not necessarily useful).
    But, as I said, I can only vouch for the sims of pedals I have actually owned (very few).

    The AMP CTRL is invaluable for saving space on my pedal board.
    The OD-20 takes up less space than a channel footswitch and a BD-2 would alone, so everything over and above that is a bonus.
    I did consider trading up to an OD-200, but it has no AMP CTRL.


    On the downsides:
    The Bottom and Tone knobs are not strictly Bass and Treble.
    There seems to be some sort of bleed over when you operate one or the other.
    Like there is a shared part of the EQ in the Mids.
    Attack Shape is a bit weird, but there is a notch in the middle of the sweep for an Off setting.
    Heavy Octave is just silly and will always remain Off.
    The "New" Yellow presets are all terrible, bar the Boost. That is a good clean boost.
    And it can't do everything so I placed a TC Spark in front of it.

    I am also on my 3rd Boss GT series multi-effect, so I must be some sort of COSM Fan-Boy.
    But I do draw the line at COSM amp sims. Never really liked them.

    (Now, if only I could dial the MT-2 sim as good as the original I could ditch the whole top row of my pedalboard!)

    This is the only COSM-based pedal I own, and as I recently learned it has a bit of a cult following and is somewhat in demand. It does sound very good, so I voted the sliced bread option.

    Roland's modeling technology. I think the roots of it go back to the 90's. They may have other, similar tech nowadays in addition to COSM but I'm not sure.

    I've got the BASSMAN pedal. Going up in price. Not going anywhere soon. I really don't know how to use it, unless you play it single between guitar and amp.

    This series is new. Doesn't say COSM.

    If COSM were the bee's knees, I would imagine it would be featured. No?

    I sense BOSS is done chasing the proverbial COSM rabbit hole. It probably sounded great inside of a Japanese stuidio, but did they try it outside of one?

    I imagine that at least half of the OD-200's tone settings are unusable which doesn't justify the cost. I'll buy used in 10 years.

    I've found same ODs are about the only useful one's too.

    I have TONEBONE Classic and it shares a lot of the same traits as Guv'nor. Probably TONEBONE Hot British even moreso. I have both on two separate boards because I like them so much. The Guv'nor setting on ME-50 is about the ONLY OD I like. OD-20 doesn't seem to sound the same. Probably is, I don't know.

    Again, I've A/Bed with some of the originals and the COSM sounds better. You can buy the OD-20 used for same price as a pedal. That's the only real value I see. You can get a fatter DS-1 than the original which is really thin.

    Does the DD-20 use this COSM system? It doesn't say so on the front panel, and it doesn't mention it in the owner's manual.
    I don't think it used COSM

    I've got an OD-200 that I bought a couple of months ago. There are indeed some options in it that don't work for me personally, but there are enough really good ones to easily justify the money in my eyes. I have four presets set up currently, but I've only scratched the surface on what it has under the hood.

    You would have thought it was COSM but the BOSS website and the manual have no mention of COSM.
    Then again, none of their other Delays or Reverbs are COSM either.
    Or the newer OD-200!

    maybe the "modeling" is just for overdrive/distortion tones?

    I thought that too, but the OD-200 does just that with no mention of COSM.
    I suspect that COSM is used to make 'exact' copies of another pedal (i.e. sim).
    The DD-20 isn't trying to copy anything specific, just providing a range of delays.

    The Boss Fender pedals are recreating something and are COSM.
    Then again the OD-200 manual is littered with names of pedals they are 'modeling' or sound 'similar' to?

    The newest Boss multi effect, the GT-1000, doesn't use COSM any more.
    They have moved on to AIRD (Augmented Impulse Response Dynamics).

    I'm not positive, but I think that the AIRD thing is just for amp & cab models, so the other effects could be using the older tech.

    There is no mention of COSM in the GT-1000 manual.
    But then again there is no mention of AIRD either!

    The GT-1000 Sound List does however have 39 references to AIRD Preamps.

    I can find no references to COSM in relation to the GT-1000, except that it is replaced by AIRD for amp modelling.

    So nothing conclusive there!

    I think COSM has been retired and was replaced by AIRD in the GT series and in the case of the OD-200 I think it's something else entirely. COSM only seemed to relate to drive products. I tried it with the GT-8 but it just didn't sound organic so would never go near it again.
