THIS. I can't knock the R40 as I've never owned one. I bought my 25 on CL for 65 bucks and it works perfectly.I love my Rumble 25.
It’s the little engine that could!

I liked my Rumble 25 but love my Studio 40.
Going from an 8" driver to a 10" with the extra wattage and features made all the difference for me. From a simple practice amp to one that can model, record and play out in low volumes made it all worthwhile.
... ... I wish the Studio 40 had an option of black face or silver face.

Totally get that @SoulReflection . I was really tempted get one of those modelers. Still might someday. Since I have the R500 it will probably be the R40 and not the 800. I like the idea of being able to dial up different models. I know you and G-Dog love those studio 40 Rumblers. Both your opinions matter to me.
But for the price (100 vs 400) and what it that R25 is capable of its great.

Thanks for those responses, Fellow Rumblers! Turns out that I got to sample both the R25 and R40 side-by-each at a local store. Not with my EUB but with a Fender P, which I am familiar with its sound. I was quite impressed with the R25's tone. The R40 was actually everything I expected it to be but, given the lack of need for any significant volume, the R25 may fill the bill. Fortunately, the guy at the store said if I got the R25 and if it's not doing the job once I try it with my EUB, I can return it to upgrade to the R40. So I 'm thinking I'll give that a try. Kinda can't lose. I'll let you know.

Even without taking into consideration it's somehow lighter than the 25 (like, w.t.f.??), the bigger speaker/enclosure really seems to make a difference in low end definition and clarity with the 40. Since it's not a tube amp that needs to be driven a bit to sound at its best, I don't see how having the extra volume/oopmh of the 40 is a bad way to go. Even if you only rarely need that extra booty, seems wise to have it and not need it, rather than need it and not have it.

The 25 is not a class D amp. That is why it is heavier than a 40. I had a 25, but it died young. I went to a 40 because it has the same front end as all the V3 Rumbles.Even without taking into consideration it's somehow lighter than the 25 (like, w.t.f.??), the bigger speaker/enclosure really seems to make a difference in low end definition and clarity with the 40.

Get the 40. I had a 25 and still have my 40. The 40 is lighter than the 25, has a bigger speaker and a better preamp system.Here’s his original post:
Hey fellow Rumblers. Advice, plz. Considering an additional Rumble. I am currently using an R200c. What I'm considering is an R25 (1x8) or R40 (1x10) for my EUB. The use would be for an otherwise strictly acoustic band (Bluegrass). Looking for something smaller for 2 reasons: 1. all acoustic so volume not really an issue, (and not wanting to intimidate the others with the R200c), and 2. since all that wattage is not necessary, something easier to transport.
My question is primarily a sound quality one, ie., 8" vs 10". I don't want my EUB to sound small and farty. Will the R25 do it or should I have an R40?
Thanks.

Yes more is more generally. But if you read what @trseal ‘s goal is maybe more is not needed. “All acoustic Bluegrass”, where “volume is not an issue” is what he needs.
AND it’s $100 vs $400. That’s before tax and and shipping and the pedal/controller which would be a must have for me for the studio. That’s another $75-100. So that Studio 40 is closer to $600 in the end as opposed to $125 for that little engine that could the Rumble 25. Maybe then in this case bigger/more isn’t better and it does come down to money.
With an extra 400 bucks in my pocket that I save getting the 25 and not the 40 I can get a bunch of other stuff. He has the R200 which fills the mid to large venue need that the R40 might serve the dual purpose of.
Can’t wait to find out how the R25 does on Tim’s acoustic bluegrass gig. Not knowing the gig/room/circumstances I’m not sure what I would do. Generally for me I would rather have more and turn down than not have enough to turn up. But if I can save a few hundred bucks and have what I need I’m good with that too….
