Thought I'd share news on a cute new killer little bass combo - got mine two months ago and can't stop talking about it!
It is the Ibanez Promethean P5110. Essentially it is a 13" square combo with a 10" speaker and a horn/tweeter. The amp section fits in the rear of the little cab and can be unscrewed by means of four thumbscrews. The amp puts out 250watts into the combo 10" and 500watts into a 4ohm load i.e. a second 8ohm cab. The amp has a host of controls/features including a 6 band eq plus bass & treble shelving controls, Vibe control, DI & tuner out, mute switch and both jack and Speakon speaker outputs. The beauty is that you can use it as a combo or stack the little 6lbs head on top of a bigger rig. The combo weights in at 26lbs and there's a gigbag available to sling the boykie over your shoulder! PS There is also a matching Promethean 10" 8ohm extension cab available.
In use on it's own it is pretty good and rather loud for it's size, but add another cab and there's a serious increase in juice and this baby could be used at most gigs. This amp gives my Genz-Benz Shuttle 9 (900watts into 4 ohms) a serious run for it's money in the loudness stakes.
Price wise, these do not come cheap and you could probably pay well over R5k as the retail is about R8k. Thanks to my music connections I got mine at what I would call a reasonable or respectable price!!
I have not seen one negative review on the net and I suggest you try it out - you will be pleasantly surprised.
