The beast is back!

The new iAMP Classic starts with the time-tested, wonderfully flexible iAMP front end - and updates it with a truly formidable power section. The intuitive, flexible EQ section has been a key ingredient in the personal sound of many players over the years - including our own Bob Gollihur, who had a very early iAmp800 for years.

The Preamp Circuitry
The iAMP Pro preamplifier circuitry consists of specially selected low noise, high bandwidth integrated circuits and support components. The original iAmp800 was highly praised for its transparent, yet easily modifiable sound; it was capable of a "girth" that not many amps could replicate. The Class D followup to the iAmp800, the iAmp Pro, was criticized by some players, who said that it didn't quite capture that same full-bodied goodness of the original power section. Well, worry not; the power section in the new iAmp Classic is a proven module that presents a clean and uncolored sound — with the same amazing power and thickness that the original iAmp800 had... just not all the weight!

If you've never seen an iAmp in person, their classic EQ section may look a little complicated; but it is pretty intuitive once you understand its concepts and interactively wrap your ears around its effects. The Deep and Contour II presets are favorites of mine, and Contour I and Bright are very nice as well. The four part section section has controls for Bass, Low-Midrange, High Midrange, and High, with a range -15db to +15db. The slider beneath each lets you select the semi-parametric center frequency that the knob affects, so you can very precisely choose and affect favorite frequency bands to dial in your sound - or dial out problem frequencies when on a "stage from hell" that might be causing "boominess" or "honking."

Includes our exclusive Gollihur Music tipsheet to get the most out of your purchaseAs an example-- getting too much finger noise from your double bass sound?? Move the High Mid slider to 1kZ, and use the dial above to subtract some of that noise! Knowing the "magic" frequencies helps, but the bottom line is: you should use your ears to make these adjustments. The EQ section can be switched in and out, which is very helpful if you are switching between two basses, and one needs more sound tailoring than the other.

The rest of the features are pretty self-explanatory, and of course for optional use, but please email me if you have any questions.  

"The thing that drew me to Euphonic Audio was the purity of the translation of my sound through their system. It has worked in such a large variety of situations from Phil Collins, TOTO, James Taylor and Carole King to Lyle Lovett, Judith Owen and on and on. It is both my live set up and my studio set up. FOH and studio engineers always say how much they appreciate the purity and clarity of the system. EA is always striving to up the bar and tweak what is already great. Just remember that you are the sound and the gear is there to allow others to hear YOU and NOT CREATE YOU!"

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.

    IAmp Classic

    Posted by Douglas Harrison on Jan 26th 2021

    EA has outdone themselves with this beast. I keep the EQ off (flat) unless of any room adjustment needed for my stingray and use contour 1 (low mid cut) for an AMAZING sound. For my upright I EQ a ton and use contour 1 or 2 to get a sound that, to me, sounds like my actual bass acoustically instead of my bass through a piezo. I can get rid of the nasal quality of the mids and get an incredible sound. This is also the only amp that actually catches some bloom from my fully carved bass. If you are on the fence like I was, do yourself a favor and get this amazing amp.
