Double Bass New ridiculously small amp from Phil Jones

[BobKay]

I gotta say that Double Four is truly remarkable. With a pre-amp I can cut a gig with a reasonable, not tippy-toe, drummer. This looks like half a Double Four. For old guys like me who subway to gigs... I'm curious.

I agree that this one-half of a double four. I've been using my Double Four for a little under a year, and really like it. I use it as a stage monitor, and use the line out to connect to a PA board. I've never tried to use it alone, although it does get very loud. For my use, this one-half version might have been sufficient. My goal was to significantly lighten my load.

While I have not seen passive radiators used in bass cabs, they are used frequently in hi if speakers and pc speakers, sometimes to good effect. Hats off to PJ to make the attempt.

Mesa Walkabout Scout cabs had them (on the bottom).

This PJB is an interesting little box. I listened through a good stereo. But there was no mic on that little cab. So it's hard to tell how they did the recording. Who knows if the video is "just" marketing with no real-world test of the tone of the amp from several feet out...

But I can see it being handy to have around.

Is there a video of its use with a double bass? I only saw the EB one.

It would seem a lot more useful to me if it had a battery in it. It's "small enough to fit in a backpack" but you can only use it where there is a power outlet?

I notice that there is no "line out." Just a headphone output. Guess it would not have worked as a stage monitor for me.

Well,
i've never owned one of the new MAS 1/6.5's but my newer 1/8 (v2) has a 800 watt ICE power module driving it. So yes it is WAY more. My older one had 500 watt ICE Power AMP.

I am ignorant about the relationship between watts and volume. My first amp was an Ampeg B15 which I think was only 35 watts, but it could handle aggressive jazz drummers with upright and R&B with my Fender.

Tube amps handle overload a lot more musically acceptable than solid state amps that distort almost immediately.
By over driving the tube amp you get a lot more useable volume out of it than with a solid state amp.

The other thing is that volume perception is logarithmic.
One one side it means to get louder you need to multiply the power to add perceived volume, so the amount of needed wattage explodes exponentially to get louder.
On the other hand a relatively small wattage is only a bit quieter than a larger one. Do a small wattage amp can work for living room volume and bit above. The percussive peaks are the problem (mostly with solid state amps).

I can see electric bass practice amp withmusic source being fed via Bluetooth, I like it for my office!

I still have my B-15N(C) (Diamond Blue Check) those early ones were 25 watts RMS. I played Holiday Inns and Ramada’s for several years with a 1966 Fender Jazz.
Drums kits were only 4 Ply. I once tried playing my Mirecourt 5/8th’s Double Bass using a Polytone Pickup. It was an epic fail . I didn’t play upright live, until I got my first Underwood pickup and a Walter Wood’s MI-100-8. I did use the B-15N’s cabinet (with an Altec 421 8H speaker) It worked fine . Once the GK 200MB’s hit the market the world changed.

I had one of those Barcus Berry's that came imbedded in a bridge and it worked. Later I added a gerry-rigged D'Armond magnetic guitar pickup to the end of the fingerboard too. When I moved to NY I replaced the Ampeg with a Polytone which sounded worse. I lived in a 5th floor walk-up.

I got a C2 cab a few months ago. I had a couple different passive radiator speaker designs, the walkabout and older AI contra combo.
I won't use a passive radiator for projecting, but it's great for monitor stuff, filling the area nearby with low end (and not the audience which is why I don't use them anymore).
And after hearing the C2, I would recommend nothing smaller than the C4 for a gig. But this 4" driver is probably ideal for a low level monitor semi acoustic nightmare-schlep... And space saver applications.

Wow, I just got to use my D4 in a jam with acoustic guitar today, and was surprised and impressed how good it sounded. But I would not have thought it would work with any drummer.

Clearly, I need to find a drummer next. For science, of course.
