Mini Rigs of Doom Four

For those who don't frequent the Revsound Club, here's my upgraded portable mini rig of doom. Revsound RS112 powered by Quilter Interbass powered by 24v battery. Produces an ear-damaging 118db of deep bass

Lots of RevSound love here! I have an RS212T (which is not my mini rig of doom though it is under 30 pounds which puts it in mini-rig status if just for the weight). My mini-rig, at least in looks, is my GR350 head and two Phil Jones C4 cabs. Ironically, that rig weighs quite a bit more than my TF500 and RS212T!

For you RS28V users, first of all, congrats! Secondly, how does it keep up with a rock band/loud drummer on stage? Front of house support generally means the cab just needs to be for you and the band and with a good monitor setup, may mean just you.

I'd love to get even smaller and lighter if the 28V can keep up. Please share your experience(s) and applications for this little wonder! Thanks!!

Here's my 'lil EA iAmp 300 and RS28V rig, I also use an Ashdown OriginAL 350 with this cab. I've had a chance to play it at a few indoor and outdoor places over the past couple weeks, classic rock, blues, Motown and soul, and it's been phenomenal soundwise, seems to defy physics. You look back at it and wonder where the rest of it is!

I have not yet found out how loud this cab can go, it has had no problems whatsoever keeping up with "moderately loud" drums in a rock setting. FWIW, this cab's feel/response is a bit like a 115 (as opposed to, say, a 210) but in a tiny, under 20-lb box. And with an under 3-lb amp it is a freakin' breeze to haul, which is critical for my needs.

I, too, am curious if anybody has tried this cab with a hard-hitting drummer, something tells me that might be asking a little too much... but dang, this cab has been a real little wonder so far for me.

This was my rig from this past weekend’s
gig. The head is a Markbass Goldline 250.
I’ve gotten compliments in the past on the sound from this rig. I also split to the pa which has two qsc k12.2 and a jbl 18” sub. Two gigs ago, the guitarist accidentally muted me in the pa and my little rig carried me through two songs before we could unmute me. (I noticed and turned up the rig volume to compensate while he figured it out.)

I got a chance to push my RS28 a little this weekend, g/b/d with a relatively loud drummer (though not insanely loud). My P bass has somewhat hot SD 1/4 lb pickups, I had the gain on the iAmp at about 1 o'clock (not quite as much as it can take) vol a bit past 1 o'clock -- I'd say about 90% of what the amp can put out. The cab sounded great, like it was happy to finally stretch its legs and run after all this time at low and moderate volume. And honestly, once things got cooking on the gig, I set up the amp for that volume level, kept the eq flat except a little extra on the highs, and never looked back at the rig the rest of the night. The complete rig felt great, smooth and full when I wanted it, growly when I asked for it

Bottom line - yeah, this thing can keep up! I was able to carry a mid-size bar. And with PA support, unless stage volume is stupid loud, this little cab can handle that job too.

Using the boxing analogy - this featherweight cab does punch way above its weight class. Not like a heavyweight, maybe not quite a welterweight, but like a strong middleweight. In my bass terms, I'd put this rig on par with my Eden WT330/210MBX 400W rig or my TH350/RS115 200W rig, but it falls short of my TH350/RS212 350W rig.

On the downside, it is "in danger of being trampled by dwarves." You can't hide your gig bags behind it on stage either.
 
Very cool! I'm curious what your home-made preamp does that the front end of the GK doesn't/can't? Thanks!

That preamp does a handful of baked in tone tweaks that I was getting from a few pieces of gear before, but rolled into a single unit via a bunch of math.
Basically, this is its internal chain:
  • Tube style even order harmonic generation and saturation
  • Noise gate
  • Optical style compressor (adjustable)
  • High and low pass filters
  • DBX 160 style compressor (set just for for the auto-leveling)
  • EQ notch cut at 300Hz and a switchable mid boost at 1.2KHz
  • Urei 1176 style compressor (set just to tame a bit)
  • Output transformer saturation
  • Optional Bass Enhance (switchable on/off)
I have a bigger, rack mount version in my gig amp which has more breakout controls:
  • Adjustable high and low pass filtering
  • Three band EQ
  • Exciter (switchable on/off)
  • Drive boost (switchable on/off)
I should probably do a thread about them.

Thank you! And YES PLEASE(!) do a thread on them!!! (and somehow link it here otherwise I'll probably never be able to find it). Thanks!!!
 
Current living room mini rig:

- Home made Eminence Kappalite 12” cab (20 lbs!)
- GK MB200 (2 lbs)
- Home mode preamp (1 lb)

All in, under 25 lbs and could easily play a small to medium sized room with it.

Can you also share more about how you made the cabinet? Does it have a tweeter?

Thanks,
JayT
 
Here is my mini rig of low volume doom that I made!!! It features all tube amplification with less than one watt of bone crushing power. It can be run in triode strapped or pentode mode with variable negative feedback to control amp character. The speakers are 4.5” wide ranges probably from the 1970’s mounted in some cigar boxes. If you’re trying to play with something louder than a ukulele your just doomed. hehe.

Thanks, it was a fun, cheap project to see how small and cheap I could build a tube amp. The enclosure is a one gang electrical box, the output transformer came from a wall wart with a 40-1 turns ratio. The tubes are a 6AU6 for the output and a 6AB4 for the preamp. The amp can be used as a stomp box due to an internal resistor on one of the output jacks. The amp could be made loud if I had a couple of 4x15 cabs though. DukeLeJeune was able to make such a cab and it weighed only 66 lbs, so not too heavy. 8 15’s or 12’s from old record consoles would be super lightweight and would work well in an open back cab for even lighter weight. A silly proposition I know, but would be fun.
