Double Bass Small amp just to boost acoustic volume some

When it comes down to it, I would have a really hard time justifying a Rumble 40 when I already own a Rumble 500.

The 500 weighs 36.5lbs and measures 23"x19"x14".
Rumble 40 weighs 18lbs and measures 16.6"x16.5"x12".

Yes some people in jazz circles will whine because the 500 looks too big. But some people whine to too much. I would tell them my amp has a volume control, so I can turn down however much is necessary.

I copied these images from Fender and resized the 500 so the handle and Fender badge are approximately the same size as the 40.

That Rumble 500 is smaller and lighter than I realized. I'm probably too spoiled by my MAS and Audiokinesis cabs to ever get one, but damn that does look like a lot of bang for the buck/pound/cubic inch!

I have the Rumble 100 and am very pleased with it. In the music store where I bought it, I almost hit myself in the face when I leaned over to pick it up. It was so light. I had been using an Ampeg B-15 tube amp for my whole career!

Even though I have a 25 and a 100, I hadn't really compared the weights. According to the spec sheet the 100 is only one pound heavier than the 25!

Now days, power amplifiers are extremely light. The speaker and cabinet create most of the weight. So, swapping out a IcE power amp isn't going to impact the weight of the cabinet very much.

Just to mention the Rumble Studio 40 has the same 10" speaker and also a compression tweeter, which I think is preferred to a piezo tweeter, iirc. It also has modelling, etc, and if you're looking for a more full range response, would be a good bet.
 
I have been using a Bose S1 pro for acoustic duos (small rooms), piano bar gigs, and busking for the last year. I plug my realist directly into it, and it sounds great with my electric bass. I also plug my vocal mic into it, acoustic guitar, use the Bluetooth for backing tracks/practice, etc… it's been a real game changer and convenience. They say the battery lasts 6 hours, I've never run out of juice yet. I bought mine used, (lucky!) but it's well worth the 600$ new.

That's interesting - I too bought a Bose S1 - for use with my acoustic guitar - I tried it briefly with my upright bass my experience with my upright and my Realist CopperHead pickup was that it wanted to distort... Any suggestions?... maybe I didn't have something tweaked quite right...

What is the input impedance of the S1?

Upright bass produces unusually strong transients that can easily overload gear with limited headroom. If there is a padded input, you might try that.

Try it with an HPF like the Fdeck.
 
AER Amp One.

IME the AER Amp One is a very nice EB amp but not so much for Double Bass at least with the three basses I tested it out with. Just my take though.
My ensemble has an endorsement with AER. We visited their factory last year, and we use their products.

I tried all four of their current bass amps in production. My favorite by far is the Basic Performer 2. It's 23 kg (about 50 pounds), so not exactly small. I mostly use it with my EUB, but it also works great with double bass. It's very, very clean.

Amp One is the compact bass amp I would suggest for double bass. Amp Two is an *amazing* bass guitar amp, and about the same size as the Basic Performer. Amp Three is a compact version of Amp Two, and they both have a more "electric" quality to their sound.
