    Well I bought one of these just over a week ago. I'm honestly so impressed. I bought it on a whim (for cheap too - was on sale) because I've been curious to try out a Champ, and my main amp is in for repair/upgrade. Now I see what all the Champ / Sweet Baby fuss is about. So simple yet so nice.

    I haven't done the cap mod (yet?). I did try running it into a 10" cabinet just to compare, but I think I like the stock 8" more.

    I'm also experimenting with pedals to see what pairs well with it. So far my top 3 ODs are the KoT, Mojo Mojo and One Control Bee, in that order. I have a Red Llama clone on order (Chicago Stompworks) so we'll see how that goes too.

    Anyway, thanks for this thread - it was helpful as I was deciding whether or not to spring for the Sweet Baby. I'm glad I did.

    Very helpful thread, thanks everybody!

    I picked up one of these new a year ago from pitbull, $199.20 shipped, and really liked it as a clean base for pedals, but I found it too loud for anything else. I got a Carl's Speaker Soak so I could get some gain out of it without wilting the plants in my apartment. Well worth it!

    I swapped out the rectifier tube for an NOS GE 5Y3GT but now the amp doesn't really break up much at any volume, so I'm not sure how I feel about it. Might go back to stock. But I also ordered a cap for C7 so I'll see how I like that first.

    I just ordered one of these too.
    Has anyone managed to get a 10 inch speaker to fit in the standard enclosure?

    I'm thinking of building a new enclosure for it but would like to try the 10" first, to see if it is worth the effort.

    I have it and I've built a bigger enclosure in the style of a narrow panel Princeton, with the idea to use an Alnico 10". I ended up keeping on the 8" but swapping the original speaker with a WGS G8C. It sounds great now (I only use it at home)
    Anyway, just one suggestion about the process to improve it:

    1 Start playing it as-is just, to properly run in tubes and speaker and dont' forget to work a lot on the pickup height regulation (don't be afraid to go very low) and get used to play with volume and tone of your tele.
    2 test different 12ax7 (they will affect a lot its personality)
    3 test different 6v6, to get to the sound you like more
    4 test as many as you can quality 8" speaker (jensen alnico, weber, wgs)
    5 build a bigger pine cabinet (it's worth the effort)
    6 leave the 10" as the last test to do if you find you really need it

    This is my set-up (original was Ruby tubes and Celestion super 8 speaker)
    12ax7 vintage NOS telefunken (branded Geloso, an italian firm of the 60s)
    6v6 Tungsol (new production)
    original Ruby rectifier
    WGS G8C speaker
    and I play with a CV Tele Blonde
    It sounds really big and with an easy break-up

    Next project is to try a Jensen 10" P10R (so bad here in Italy Webers are not easily found)

    here some pics of the new cabinet:

    Wow! Looks great.
    Thx for all the info.
    Still interested to know if the 10 will go into the std enclosure?
    I have a slightly different idea for the new enclosure.

    I'm not sure I wud spend so much money testing all the stuff you suggested (it's only a $200 amp) but I have some stuff lying around that I want to use. The Tolex will be my biggest expense.

    My suggestion about components to try is of course without buying them all, but relying on things at hand, friends and bandmates support... Anyway a 10" in terms of diameter will fit the original enclosure but depth will vary from speaker to speaker. Most probably You'll have to get rid of the metal cage that protects the tubes to leave enough room for the magnet, but I think that any 10" in a so small cabinet will not express itself at its best. An easier way could be plugging the amp in a separate cabinet (or to the speaker of another amp) and get an idea of what could be the result.
    Just one word about the 200$ amp: do not underestimate it, it can pair any 5F1 kit amp that has way higher prices!
    Let us know your impressions once you'll receive it!

    Great, thx for the info.
    The 10 I want to use is a very small magnet Jensen C10R and I wud expect to remove the tube cage. I have a few tubes to try but nothing fancy (JJ's, EH n GTs) and I'll prob do the C7 cap mod.

    I'm thinking of an enclosure more like an original Fender Champ but a bit bigger and with the slant front. Prob go for a vintage look but not tweed. I have some cane grill cloth left over from another job and still to decide on the Tolex colour.
