A first-upgrade bass amp

I'm posting this to Gearslutz and Talkbass with the hope of quickly reaching as many people as possible. Apologies for the double post if you should stumble across it on both sites.
I'm looking for an appropriate "first upgrade" to the starter bass amp (Ampeg BA108) we got my son when he began playing bass 2.5 years ago. Our requirements are many and specific and, in truth, possibily unattainable when taken in the aggregate! With that in mind, I'm hoping I can outline my situation and get advice from experts on these forums, whose expertise and understanding greatly exceeds my own!

SON

He turned 12 last week. He's still several years away from having Paul McCartney open for him on his bands' first World Tour. He plays a Squier Vintage Modified Jaguar short-scale bass.

Bass is his second instrument; he's a drummer first. His bass chops are well behind where he's at on drums, but he enjoys playing and is improving rapidly. He has a good ear and intuitively understands how rock/pop songs are arranged.

He's a member of the House Band at a local School of Rock chapter and gigs often (50+ shows before his 12th birthday). The setlists are almost exclusively classic rock from the 60's through the 80's, with the occasional crossover pop/country hit thrown in.

STUDIO

The studio where we practice is approximately 20' x 15'. It has Pergo laminate flooring and a drop ceiling with acoustic tiles. It's a pleasant space but is otherwise completely untreated with bass traps, diffusers, etc.

BUDGET

I'd like to stay below $600 USD, preferably closer to $500.

PIE-IN-THE-SKY HOPE

Given all of the above, I'm looking for an amp that meets these criteria to the largest degree possible:

- Good tone at any volume, with aesthetics "cool" enough to inspire him to play and, even more importantly, to practice (which he does NOT love).

- Small footprint and relatively lightweight. School of Rock provides gear for the shows and band practices he has now but I'm certain he'll be forming his first band within 2 years -- so he'll need to cart this rig around soon. He's still a little guy and can't lug around a cabinet that outweighs him.

- Enough power to be heard over a drum kit when practicing and to get the job done at a gig if properly mic'd into the PA.

- Something that he will not outgrow for years (if ever), but that is also not overkill. My money-tree withered and died years ago and we aren't playing Arrowhead Stadium anytime soon.

- Prefer a 2 x 10 to a 1 x 15, given the modestly-sized studio. It's can get fairly muddy in here.

CONTENDERS

The leaders in the clubhouse are:

- Ampeg SVT Micro VR w/ SVT-210AV 2 x 10 cabinet
- TC Electronic BH250 w/ K210 2 x 10 cabinet
- Fender Rumble 200 1 x 15 combo or Fender Rumble 500 2 x 10 combo

Additionally, a local Guitar Center has a used Ampeg PF350 w/ PF210HE 2 x 10 cabinet selling at $430. It's in good cosmetic shape but I'm concerned there is a mechanical issue somewhere. The volume was well below what I expected. I demo'd it and several others yesterday, including the Rumble 200. When listening to each amp, I zeroed out all EQ settings, disabled any sound-shaping options like "Vintage" on the Fenders, and set gain and master volume to 50%. Even 100 watt combo amps were significantly louder than the PF350/PF210HE. The GC rep said he'd ask their tech to take a look at it today. If the issue is corrected (or if it's pilot error -- I'm no bassist!), I think this sounds like a good deal and a good fit for our needs.

SUMMARY

So, all I want is an amp that's small and lightweight yet has plenty of power (but not TOO much), has killer tone, looks great, works perfectly in every studio and stage role, is ideal both now and in the future, and that is dirt cheap.

Easy, right?

 

Wow, that's a lot of love for the Fender Rumbles! I was personally leaning toward the Ampeg SVT, and my son seems enamored with the TonePrint function of the TC Electronic BH250 (plus, the black and red cabinet design is undeniably cool looking -- which, again, is a factor that he places WAY too much value on, in my opinion).

My only concern about the Rumbles is that they sort of split the sweet spot to either side for our situation. I'd fear that the 200C wouldn't be loud enough to play over the drums and the 1 x 15 would exacerbate the muddiness and bass buildup in my 300 square foot studio (I base that only on my reading about 1 x 15 vs 2 x 10, not through personal experience; please correct me if you think I'm wrong). The 500C is $600 and perhaps more power than needed.

The "not loud enough" and "damn, it's expensive" concerns worry me about the SVT Micro and BH250, as well. That's why I was strongly considering the used PF350 w/ 2 x 10 cab at Guitar Center for $430. Of course, buying brick-and-mortar means another $35 tax vs. buying from Sweetwater, so not as great a deal as it seems. It just seems like the absolute ideal product for our specific need doesn't exist. So if I have to get out of my comfort zone, I guess I just need advice from people with real-world experience. Is 200 watts enough? Is a 2 x 10 a better fit for my studio than 1 x 15? That sort of thing. I wish I could demo a few in-home, but can't.

I deeply explored other options, including the Carvin BX250 w/ 2 x 10 cab, a Markbass Littlemark 250 w/ 102P Traveler (sweet!), a GK MB200 w/ CX210 and more. All were out of my price range new. This is going to be a gift, so I'd really prefer new unless it was a really good deal, which I think the used PF350 at GC is. Quality used gear can be hard to come by on Craigslist, as well, and I don't want to wait months. eBay is an option, but can be even more challenging than CL because of the high cost to ship a cabinet.

Additionally, I ruled out some other brands that (fairly or unfairly), I have always perceived to be a step below industry heavyweights. These included Peavey and Acoustic, and honestly TC Electronic, but my son really loved the TonePrint and tuner functions of the BH250, so I kept them in consideration.

I know I'm all over the place and this sort of newbie question must be irritating to forum regulars who have seen it asked and answered ad nauseum. I appreciate your indulgence and advice!

 

Yes, the studio is mine and, honestly, calling it a "studio" oversells it somewhat! It's the room where all my gear and recording computer sit.

There is a small drum stage in one corner w/ a Gretsch Catalina Maple Kit. The bass amp sits in an adjacent corner. On the opposite end of the room is my desk with my mixer/interface, studio monitors, PA speaker, etc. The photos below were taken from approximately the same spot in the middle of the room, looking both directions down the long axis of the room. (BRAG! the drum stage and studio desk are both DIY projects of which I'm quite proud!)

There is one large throw rug in the middle of the room. The ceiling tiles (allegedly) have some minimal absorption. I guess while I'm bragging of DIY skills, I should also point out that when I originally studding out the room, putting up drywall and install flooring/ceiling, I had the perfect opportunity to put rockwool or similar insulation into the walls between the studs but did not because this room was originally a home office. Only later did i convert it to a studio and that missed opportunity is my biggest regret about this room.

I have considered some DIY bass traps and first-reflection absorption but the room is already so small that I hate making it even more cramped than it already is. At the very least, I should probably put SOME kind of absorption up on the wood paneling on the walls and ceiling of the stage. It gets really loud.

We have a pair a headphone-style ear protection for my son, but we don't use it as often as we should. We also bought some bluetooth headphones so he can practice along with his SoR songs on YouTube, but also use it less than we should because then I can't hear the song and help him pick out the parts. The next step, I think, will be a multi-receiver IEM solution so we can both hear the song and protect our ears. Especially his. I'm old and blind already, so what if I go deaf, too?
