Manufacturer's Description for Hartke Model 4000 Bass Amplifier Head

The Hartke HA4000 offers all the newest concepts in state-of-the-art bass amplification.

Features
Power to spare - a whopping 400 watts into 4 ohms.

Two independent inputs accommodate both passive and active bass guitars. It is almost impossible to overload the input of your HA4000!

Dual speaker outputs so you can connect two 8 ohm speaker cabinets without the need for daisy-chaining.

Protection relay circuitry protects connected speakers from dangerous overloading, and prevents "thumps" when powering on or off.

Fan-cooled to avoid thermal and overheating problems.

Dual effect loop send and return jacks (one pair post-EQ and the other pre-EQ) allow you to connect to professional outboard effects processors.

Electronically balanced XLR Direct and Preamp outputs provide a convenient means of routing signal to professional mixing consoles in both live performance and recording environments. In addition, an unbalanced 1/4 in. line output allows you to connect slave amplifiers.

Ground lift switch helps prevent hum or buzz from entering the Direct Out and Preamp Out signals.

Four bands of high-quality equalization allow you to create a broad range of tonal colors for your bass instrument. The 2 mid-bands are fully parametric, with sweepable center frequency and adjustable bandwidth control.

Provides a fifth, "DBASS" (Deep Bass) band - a harmonic enhancer adds extremely low frequencies to your bass signal.

A unique contour filtering system called "Shape" activates a multi-band equalization curve and notch filter specially designed to enhance the sound of the electric bass. Front-panel Shape and Intensity controls allow you to continuously sweep the filter through various frequency areas in order to customize the effect of the curve to the specific tonal characteristics of your particular bass instrument.

A unique dedicated "SBASS" (Sub Bass) output provides subharmonic line-level signal for connection to an external amplifier driving a subwoofer.

A front-panel Audio Mute control and rear-panel Mute footswitch input allow you to temporarily silence all outputsÖexcept the dedicated Tuner output - while tuning your bass.

Side handle for convenient, easy transporting.

Rugged construction makes the HA4000 eminently roadworthy. zZounds is an authorized dealer of Hartke products.

This review has been selected by our experts as particularly helpful. "Great Head"

Sound: I wasn't very familiar with banwidth and frequencies that come along with the mids in this amp, but after I took some time to figure out what which frequency does what, and how much bandwith will do to the sound, I can now easily make any tone I want. You just have to learn what does what, and you can easily find any genre tone in literally seconds. As far as overall tone, fantastic, very very clean, and open sounding. Doesn't sound "cloudy" or like your sound is coming from another room like some cheap heads do. And also, very deep. I have managed to get a very deep, yet bright, twangy sound. You can literally do anything with this head. Feature: Has all the tonal control you need. Quality: I've had it dropped, banged, carried through downpours, and it still puts on a great show at gigs. The carry handle is very conveniently placed. Road-worthy to the max. Value: Definately worth it's price. Manufacturer Support: Never had to deal with Hartke. Thier products are EXTREMELY road-worthy. Never had a problem. The Wow Factor: Definately Hartke's best dynamic and parametric head. However, for only $200 you can get the extremely loud 7000 head, with tubes, and and 10-band graphic EQ. But, if your not one for the complexity of tubes and graphic equalizers, you get the bang for your buck out of the 4000. Loud, good, clean, deep tone, durable. This head is great. Overall: My first head, and my last, unless i get the money for the 7000, but even so, for anyone into the bar, and small venue scene, the 4000 is all you need.

zZounds has verified that this customer bought this product from us. "TURN IT UP>>>>>>>>PLEASE!!!"

Sound: I have played Ampeg, Peavey and Galien Krueger. This head just does everything better. It's SO MUCH LIGHTER than my old SVT. And yes Toto, it has the same tone ability as a tube amp. I use two Hartke 15 cabinets with it and it shakes the house. Unlimited tonal capability and a "Low Bass" control that is remarkable. The toneal ability of this amp is one of its high points. 400 watts rms ain't so bad either. Feature: Built like a tank. Detachable power cord and very well written users manual. Has clipping light as well as protect light and a varaible fan for cooling. Quality: Built like a tank!! Looked inside. Huge transformer, multipal printed circuit boards and power transistors are bolted to a "Chimney" cooler that the fan blows thru. Value: Worth every penny. A steal for the going price. Manufacturer Support: Dealt with customer service on a cabinet issue. Great response. Talked to a guy named "Fritz". Great experience. The Wow Factor: It's an attractive head, but it could of have been designed with a metal faceplate instead of plastic. You can't touch it's tonal control, so I guess that's where the faceplate money went. Overall: Sastified. Not looking to buy any more equiptment.

Style of Music: progressive rock
