the NEW Euphonic Audio Micro
the more powerful update to the popular Micro 300

The original Micro 300 was a true wonder, a tiny but powerful, feature-filled amp. At around three pounds, this Class D amp delivered 300 watts into a four or two ohm load. The newest Micro will also offer two channels with independent three-band equalization, and when using one input only you can switch from one channel to another using a footswitch! (not included, see below for some switch suggestions). The newest Micro (due in March/April 2009) bumps the power to 550 watts

The newest Micro will address the need for worldwide voltage levels we encounter in different countries and on the stage from hell (I've been there, and I'll bet you have, too). The proven power supply has a jumper to switch between 110 and 220 volt ranges, each with a wide band of tolerances.

The Wizzy 10 can make an excellent companion speaker for a powerful yet compact rig. In spite of being so light and compact it can deliver quite a punch. At the right is a photo of true Bass Bliss, with Bob at a September 2008 outdoor party gig playing a Micro 300/Wizzy 10 rig. Carrying it in and out of a gig was bliss, too.

Upright Bass and other acoustic instrument players should take a look at the extra features in the new Doubler specifically added for acoustic instruments!

  • Inputs: Two separate and distinct channels with individual controls.
  • Trim controls to adjust the overall level of channel one, channel two, the DI output, and choose frequency for high pass filter
  • Intelligent Input Switching with optional footswitch; you can use a single or double momentary contact footswitch (examples of footswitches that should be compatible are the Boss FS-6 and Rolls RP8)
    • With one instrument plugged in, the switch toggles the instrument between channel one and channel two, so there can be different settings
    • with two instruments plugged in, the switch moves from channel one » channel two » both
    • a single footswitch controls the Intelligent Input Switching; when a double (¼" TRS plug) switch is used, the second button controls the mute function

  • EQ: Low, Mid, and High for each channel
  • Variable high pass filter 22-80hz., 6db per octave (allows you to select a frequency below which response is reduce, to help with boomy rooms and stages), mini-pot at edge of top

    • Effects loop is inserted in
      • Channel One only
      • Channel One and Two are both affected (default)

  • 1Meg ohm input impedance on both 1/4" inputs
  • Variable high pass filter (allows you to select a frequency below which response is reduced, to help with boomy rooms and stages)
  • Frequency Response: 20Hz to 20kHz ± 3dB

EA thinks you're smart: They use REAL Volume Controls

Rather than have all the volume in the first turn of the knob, EA uses potentiometers that are more linear. This means you may actually have to turn the master volume all the way up to the 3 o'clock position when things get really, really loud. This gives you a more realistic measure of how much power you are using. Most other amp manufacturers (and think stereos, car radios, etc.) use a taper that puts all the volume up front. This is to impress unsuspecting customers trying gear in stores. "Wow, listen to how loud it is, and it's only on 2? ," he says, and thinks to himself, ”This thing must get really loud!!”

Nope, they're just fooling with you. It pretty much stops getting louder around 5, and then only gets more distorted. EA thinks it's better to use the entire volume control. You'll otherwise never actually attain the mythic eleven.

Is this an EA Exclusive?? We're not sure, but we think others should follow their example. Euphonic Audio says respect your customers, don't try to fool them.

Euphonic Audio doesn't make a padded bag for the Micro or Doubler. They do have the Duo Bag that will carry their Wizzy 10 and a Micro or Doubler.

I (Bob) use one of our own Gollihur Music Gig Bags to tote my Doubler, but with the following proviso: While I trust that the 5mm padding on the bottom, top, and back in the interior pocket of the bag is sufficient for my personal, casual, "carry it yourself" protection, don't let your (fill in your own clumsy musician) carry it or energetically throw it into the back of the band van!

Wow! Wow! Wow!

Wow#1: I hung up the phone at 4:20pm East Coast time; your shipment arrived at my West Coast address at 11:05am West Coast time. That's coast to coast shipping in less than 24 hours!

Wow#2: The EA iAMP Micro is incredibly clean, amazingly powerful and impossibly light!

Wow#3: The Wizzy 12 MLine is awesome; I've never heard my B string so loud and clear. And crystal clean -- when I played my old bass head through it, I heard amplifier noise that I never heard before.

On a customer satisfaction scale of 0 to 10, I'm at 11! I am delighted. Thank you Mark!
Howie W (Sept 2010)
Thank you once again for the outstanding customer service! The EA Micro arrived the other day and I gigged with it last night. What an amazing little box of wonder! The Micro coupled with the Wizzy-12 held it's own very well with my '74 P-bass and '67 Kay.

@Mark - thanks for setting the amp up for the 2-ch switch. That was very nice of you to do that.

Again, thank you for your past exemplary customer service and support.
Bob P (April 2011)
Just installed my new Realist Lifeline pickup- A/B'ed it with my R********* S*** - it's a LOT hotter and gives a big fat sound without fussing around with it. On last night's gig in a fairly large room, playing rockabilly with a drummer that uses his sticks as anger management devices, had no feedback issues playing at pretty high volumes- loud enough to feel the bass thump through the stage. Love, love love it! I was playing through my also new EA micro 550/Wizzy 10 rig. I anticipated using direct out to the house PA, and using my amp for stage volume only. Well that wasn't so. I was going it alone, and my teensy little rig just blew the house down! The whole set up was nice and loud when I hit the string, and when I really dug in, it just got louder! And finally, the tone was great too- I hate fussing with controls on the amp; just set and forget is my motto. The sound from this set up was nice and big and fat. Very much "my bass only louder". 18 pounds! My favorite rig ever!
Jon P (June 2016)
Hey guys, I have further testimony regarding the EA eensy teensy Iamp Micro 550 and the Realist Lifeline pickup. I had an outdoor gig at a car show/rockabilly festival and was a little dubious as to how the rig would handle the great outdoors. Now this is no Marshall stack- but it acquitted itself very well in my old school - read authentic to the 50's - rockabilly band. We aren't the shot heard round the world, volume wise, but I was super happy as to how the hot little lifeline/Iamp 550 Wizzy 10 worked. It's a kick just to get the big sound out of a sub 20 pound package! The only complaint is that the Wizzy 10 box really isn't big enough to lean my bass against on breaks- i just lay the beast down instead.
