To balance out that kind of voicing it often works best to either have a cab that's pretty tight on the bottom (Bergantino AE or possibly the NV610, most of the Schroeder gear, a lot of the Bag End lineup, etc.) or a cabinet that's really built to utilize that deep low end extension (Greenboy's fEarful designs and all of their variants that utilize the 3015LF driver, Acme B series, BFM, etc.).

Gotcha. I asked because I recently purchased an iAmp Pro of my own - though I haven't fired it up yet. Am waiting to receive the matched pair of LDS 12/6/1 "nEarfuls" I ordered from Don Oatman about three months ago. When I get 'em, I'll have a rig similar to the one Ukiah Bass has - only with a second KL 3012LF, rather than the KL 3015LF.

Can't wait to experience the awesomeness of it all... :hyper:

+1 It's true: The more you crank, the more you get. :D


The GAIN and VOLUME knobs on EA heads behave far differently than most amps. If your cabs can handle it and the venue calls for it, you achieve maximum gain and volume by turning these knobs far closer to their maximum settings than on other amps.

With most other amps, maximum volume seems to be achieved by the time you reach the 11:00 position, from which someone unfamilar with EA amps may falsely infer EA amps aren't as loud as other amps.
 
Did you play through it with the EQ turned off and all the contours and Q controls off? To me, it's the sound of my bass with just about 0 coloration. At that point there's no voicing at all to make anything too low or too wide at any frequency. But even if you still feel the natural sound of your bass is too low, you can use the EQ section to select literally ANY frequency along the spectrum and EQ it out. I really never understand when people say they find the voicing too deep....just don't make it so deep!
As I said in my previous post, no amount of tweaking the EQ sliders or the level control for each band could tighten up the low end. As has been posted about these amps many times on TB, the iAmp stuff has a very deep low end rolloff compared to the typically higher set HPF in most amps available. There's simply a component to these that prevents you from dialing in the low end to be more of a conventional voicing. The reality is that if you don't want that type of voicing (as a Tecamp Puma1000 owner, I happen to like that voicing) this would likely be a bad choice of head for you.

The iAmp Pro and a nEarful is a "can't-miss" combination. Very modern, very wide and very capable of handling all of it with ease. That will be a killer rig.

+1 to Silky's comments above. That rig is going to KICK. Don (LDS) loves the Puma heads above all others with the LF boxes, and I would agree with him. That super deep low bass extension, and very clean midrange, and the hi fi upper treble extension, which can kind of destroy other cabs (or sound very 'sterile') just sings with the Puma, which has at least a somewhat similar voicing to the iAmp800 that I owned for a while. It has been reported that the low end of the Pro has been tweaked to be a touch tighter, which is even better.

The power rating and voicing of the iAmpPro should be perfect for that rig. I did find the iAmp800 quite fussy regarding cab matching though, but the match you are planning should really be something.

Also, just like the Glock heads and the Puma heads, and as mentioned above, the gain and master pot tapers are more of the 'non linear/audio taper' design, which means you need to crank them quite a bit more to achieve full performance. With a relatively low output bass, the gain control on the iAmp and the Puma can easily reach 3 o'clock for optimum performance.

I'm hoping to have a look and quick try of Mystic's Pro (if he doesn't mind) while it is at Don's getting fit for the matching headcase:bassist: That is going to be a killer rig.
 
Slightly off topic but I just saw in bass gear magazine EA advertising the NL410. Anybody have details on that? New drivers maybe? Old ad?

I agree with Mitch that the iamp pro is very versatile and sounds good with many cabs. It is much different then the iamp 800/500 and I'd hesitate in following the opinions of those who are assuming they have similar characteristics.

Not true at all. I admit it takes some tweaking, but I'm able to dial in a tight and punchy low end with the iAmp 800. The iAmp Pro I had could not even approach the punchiness of the 800. Of course having speakers that can handle the 800 is key and the CXL112's do that for me. I've owned just about every amp ever mentioned on this forum and the iAmp 800 is the best sounding amp I've ever owned.

Also don't think that just because a cab that may have good low end extension will work better with the iAmp. The Acme for example is a HORRIBLE combination!!

+1 That's what is so cool about the 15/6's. They are nothing like the Acme's with that super low tuning. The key to the 15/6 cabs, with that amazing 3015LF driver, is that they are tuned similarly to many other cabs... not quite sure... 48hz, something like that. BUT, they can actually totally handle the low frequencies mechanically without farting out...ever (i.e., huge xmax, xmech, and high thermal ratings also)!. So a head with a good dose of true, deep low end extension like the iAmp800 (again, haven't played the Pro) or the TecAmp Puma, just sings with that particular cab design. The first harmonic of the B string just KILLS.... you can burp the open B like an open A string!

Also, the stock 3015LF cabs only come in 8ohm version, so the significant ooomph and wattage of a monoblock, high powered head like the iAmpPro really puts that nice 500-600 watt into 8ohms power into these cabs that can actually use that wattage.

Nice stuff! I too found my Acme's to sound much better either hi passed or with a head that was much tighter and more rolled off down low, like the Walter Woods or the Markbass heads, etc.
 
To OP

I am a recently comer to EA. I have been playing more EUB and bought a Wizzy 10 here on TB and then a Micro550 head new from Jong in DC (Jive Sound). It is primarily used for its portability (the entire rig fits into a backpack case you carry on your back) for jazz gigs where we are doing either a jazz gig in a smaller room, or are playing a wedding dance where they have requested our jazz group for the cocktail hour in a room separate from where the full dance band has set up. It works great for that application. I have had very good experience with customer service, Gary, in particular. When I got the head, I had absolutely no headroom using my passive NS EUB. There are volume trim pots on the head and those were maxed. An email to EA and Gary responded to send it back in as they ship them out very conservative on the volume trims inside the head, really not at the full 550W at 4 ohms. After getting it back, I've got plenty of headroom now, very satisfied in the amount of volume I can dial up without crapping out the Wizzy10. In addition, the Micro 550 sounds great with my Schroeder 1212BMF and my Walkabout Scout 12 cab. I'd like to get my hands on a Schroeder 15+L or perhaps a Bergantino 15 to perhaps use with the Micro head for the full band and my BGs on a gig.

So yea, I'm a fan of EA.
 
I bought a used M-Line 12 cab from TB's Tony Moore back in 2007 when the M-Lines were garnering a lot of discussion and interest here on TB. I've used it for more shows than any other cab I own, and it simply sounds terrific. That cab puts out a ton of sound for its size. It's EA's mainstay cab nowadays, but there is no longer much discussion on TB. It's one that a lot of players who aren't familiar with EA gear passed on trying at its peak of interest here, possibly because it was harder to get back then than it is now. Also the fact that they aren't found in music stores very often has kept them under the radar.

I consider it one of the best single 12 cabs on the market. It is small, easy to carry, lightweight, does not have a crossover, and the fact that it's now available in either 8 or 4 ohms means a player can buy two for a very loud setup with a 4 ohm minimum class D head, or use the same head with a single 4 ohm cab that is loud, assertive and easily capable of serving as a small to medium room filler stage amp or as an excellent monitor for a large PA set. There is nothing not to like about the M-Line for probably the vast majority of players who are not in crushingly loud metal bands.

If you haven't tried the M-Line, you need to! It's one of those cabs that will stand the test of time- it almost can't be improved in any way other than power handling - as long as EA is in business.
 
Lots of EA love IME. The wizzy 12 is a superb cab and the iAMP Pro a full featured monster. I liked the 500 as wll. The new micro is not very loud, but it's feature set and clean tone are great.
 
Absolutely true. The iAmp Pro that I tried had tons of sub bass content that no amount of tweaking could dial out.

As I've stated before, I happen to like that voicing, but would just advise people to make an educated choice about cabinet selection with this head.

Try owning the amp for a while before you state what it will or will not do. Demo'ing one in a store doesn't exactly give you much experience with the amp.

Knowing whether or not it has a very low rolloff requires owning an amp... Hmmmm... I had no idea. Thanks for educating me :rolleyes:

I demo'd the amp extensively through a multitude of cabinets. Actually to the point that Evan at BassNW was getting visibly tired of me... Well, maybe not tired of me, but he was definitely ready for me to buy the thing :p

My findings would hold just as true if I had bought the amp or if I didn't. I'm not saying that this amp wouldn't work great for a lot of people, myself included. Stop taking exception to a simple fact and realize that this amp has a very low HPF, or maybe none at all. That's all I'm saying. I'm not devaluing the amp by saying so. I read elsewhere in this thread that EA has since tightened up the low end on these heads. The one I played was shortly after their release, so it definitely had the original voicing, assuming that EA did revise the voicing in such a way THAT MIRRORS EXACTLY WHAT I'VE BEEN SAYING.
