The best amp I've ever played out of

By Obscured Bass

from Reno, NV

This amp not only has the control over my sound that I've been looking for, it has that Warwick signature growl that I love. It's a very versatile amp and I recommend it for anyone playing any style.


Good Value

By Augusto

from Melbourne, Australia

I started using the prophet II (250 watts) and felt the sound was pretty warm for a transistor amp so decided to upgrade to tghe P.IV as I needed more volume. The Prophet IV is an overall good amp, plenty of tonal capabilities and, although It can get a bit harsh in the high mids department, it has a geneal warm tone that is pleasant to hear and cuts through.My only objection is that the limiter doesn't handle the low B very well, the amp clips a bit too much. Having said that, I'm not giging with loud bands anymore and I'm basically after versatile gear. I'm currently using a G&L 2500(awesome bass)an Eden 2X10 and a Trace Elliot 1X15. I also use a BOSS Limiter Enhancer.


Pro Fet IV

By J.--zWC_

from Finland

Like the sound and the looks, too. EQ is pretty good, though it doesn't include the lowest frequencies (down to 70 hz only). The cutters/boosters are a good idea. My cabinet Warwick 115 pro is made for 8 ohms load and the head is for 4 ohms, so I quess that's reason why I didn't find the amp too powerful. The preamp clips too easily, too.Anyway, a good amp for many kinds of situations. I believe it's at its best with two cabs, for example one 15 inch and one 4x10.


Great amp!

By SirGigsaLot

from Washington, DC

Lots of features and volume for the price. I've run this amp either through an Ampeg 12" Portabass cabinet or an Ashdown 4-10 cabinet and it sounds great. I use the "DI Out" to the mixing board in larger clubs--a feature many amps don't have in this price range. Plus, the amp has bass, mid, and treble boost switches in addition to the graphic EQ. Lots of tone shaping possibilities here! On the down side, with treble boost, graphic EQ, and tone setting at greater than 50% there is a noticable hum--knocking off the treble boost or dialing down the tone took care of this though. Also, the amp has one "Speakon connector" recepticle (no 1/4" jack)and my Ashdown cabinet only accomodates 1/4" jacks. Had to buy an $18 adapter to connect them. Overall, a really great amp--hundreds of dollars cheaper than the least expensive Ampeg. It's worth twice as much as it costs!


Great Smooth Deep Sound!

By Anonymous

from Undisclosed

Great Low Sound that Warwick loves to bring. To me I use Warwick amplification and bass guitars for deep and smooth sound and with the Pro FET IV I am once again impresses


Warwick profet IV

By bassdude3452

from Wales

This amp is pretty amazing for the price. It's really versatile, I play a load of styles and it's good for everything and I can easily change the sound at a flick of a switch. It's loud as hell aswell, I have 2 guitarist playing 100 watters in my band and a loud drummer and they are usually struggling to keep up with it. If you are in 2 minds as to wether to buy this amp I would say buy it, you will not be disappointed.
