Summary: I prefer the slide controls versus knobs for equalization but at this price who cares? I added an equalization pedal with slides and all is well. As everyone else says the Ultrabass function is a gimmick and it didn't cost anymore and you don't have to use it. Before I purchased I checked with other bassists in area who were familiar and all said it's a good one. They were correct. I have had this head for over 5 years now, still going strong.
Pros: Power, price and sound.
Cons: Heavy and dials are tough to reset accurately to duplicate sounds.
Summary: I am a definate fan of this head, i just bpught it recently for the second time. I sold my previous one to a friend because i finally got the Ampeg svt that I had long wanted. I myself dont feel that the ultrabass function is the best synth or sub octo deal out there by far but being a bass player that does a lot with r&b and neo soul artists, I have found it to be useful.
Summary: I bought this along with the Behringer BA410 cabinet - the total price coming in just under $1000 after taxes. You can't build a bass stack at that price with any other brand. Low prices can often be an indication of poor design but considering I was working on a very limited budget and wanted to leave behind the world of combo amps I thought I would take the plunge-after all I needed to start somewhere. I have to say, I was actually really happy with the set up.
Pros: Great tone, straight forward controls, affordable
Cons: Not serviceable, ultrabass subharmonics are poor, cheap plastic parts
Summary: First off, this is a 450w bass head for less than £200. That makes it quite impressive already. Added to that the list of controls and functions and it becomes more impressive all the time. I run it through a Hartke 410TP at 8ohms giving 290w. It performs very well like this and seems to be a fairly transparent amp with the eq flat, just letting the sound of the guitar through and allowing the speakers to voice it.
Pros: Cheap, simple, good range of controls & functions.
Cons: Post EQ DI, touchy preamp, Ultrabass function.
Summary: Love the sound of this thing!!! I Run it with a Mesa 4x10 and a black widow 15". I love the shape feature, with the variable knob and on/off swich. Would recomend to everyone. Know several bassist in my area who use it. Just wish it had more power.
