[quote name='Mr. Foxen' timestamp='1383430578' post='2264518'] Knob position doesn't relate to much, and flat eq and knobs in the middle are two totally different things. [/quote] I'm sure they are, but whatever way you wouldn't set it up - GK was still delivering more power and punch than Ampeg - hence I've decided to go for this one.

[quote name='shybaldbuddhist' timestamp='1383319532' post='2263153'] An update from the OP. I ended up getting the PF 350 which i have now returned for a refund for several reasons. The amp turned out to be underpowered for what i need, the limiter would kick in even at relatively low volumes. Also, the 'balanced' XLR on the back of the amp doesn't appear to be balanced at all. The signal into the PA was really hot even with the gain at 10 o'clock. And the lack of a pad meant i'd need to run it into a DI box. These problems coupled with the reliability issues worried me enough to take up the 7 day returns policy of the shop. I've now ordered a GK MB500. Fingers crossed it's better than the Ampeg! [/quote] I just got my GK Fusion 550 - it's a real beast and I was going to buy Ampeg SVT 4 Pro - but tried GK and it is just unreal - I'm sure you won't be disappointed.

Thanks very much everyone for participating - I can see the conversation went a bit off topic I'm now back with my new amp - and the winner is Gallien Krueger Fusion 550 - what a head! After checking the SVT 4 Pro and the GK 1001RB I've also decided to test this one and it beats the other two no questions. Ampeg didn't win this battle for the following reasons: - they appear to not be very reliable - even the guy in the shop confirmed it. - comparing to the GK Fusion 550 - even though both are suppose to run at 350W @ 8 ohms it was NOT delivering as much volume as GK with the same gain and volume position and with the flat EQ - really strange as I've also read about it a few times people were complaining about it not being very loud. - the cost comparing to GK was much higher for not really much benefit - I got the GK for £713.00 when Ampeg was £1245.00 The GK is a serious beast - doesn't look like it at first and 500 watts doesn't seem to sound like much, but after plugging in my 5 string Warwick corvette with pretty tired DR strings and connecting it to my Carvin cab, the sound it produced was just unreal. If you haven't yet I strongly recommend you guys try this amp next time you're in the music store. Thanks again for participating and all the best everyone.

[quote name='JapanAxe' timestamp='1383305051' post='2262838'] The SVT 7 Pro has had its problems too - its power amp is Class D like the PF500. There are always used SVT 3 Pro heads available on BC, I should know I'm still following the threads despite having just bought a Genz Benz! [/quote] How's the Genz working for you? Also - if you don't mind me asking - what sort of style you're in?

[quote name='chris_b' timestamp='1383305786' post='2262851'] How loud are you going to play? Why do you want to choose between these hugely powerful amps? They are overspec'ed for your cab and you could get a better matched amp for a lot less than the cost of these monsters. I would be looking at an amp giving out 500-600 watts at 4 ohms. The PRO7 has a chequered history of failures. There are a couple of Mesa Boogie M6 amps in the FS section and Bassgear have Carvin amps. I'd also checkout Genz Benz Streamliner 600/900 amps. [/quote] I'm going to be potentially pretty loud - it's for rather heavy klunky sound with low D etc. but also for funk and R&B - hence the amp should be pretty versatile. I've heard about Ampegs and its failures - that's why I'm still not 100% on with my decision apart from the fact that I obviously need to try them first. Looking at SVT 4 Pro and 350W @ 8 ohms vs Carvin 600W @ 8 ohms - should these two work together ok? Also - I had Carving R1000 and it was a fantastic amp, but unfortunately something wen't wrong with it and no-one around could repair it so I had to sell it for parts. Now I'm looking for a bit more agressive sound hence my choice of the amps.

[quote name='Bill Fitzmaurice' timestamp='1383308808' post='2262914'] The cabs power rating is how much it can take before the voice coils melt. In most cases that's well above how much the cab can take before the drivers distort (displacement limited power). Cab companies should tell you what the displacement limited power is, but they won't, since the much lower figure would impact sales. In practice you'll never over-power a cab if you don't push it beyond the point where you hear distortion. That means an amp rated anywhere between one-half and twice the power rating of your cabs is usually appropriate. Less than half probably won't drive your cabs to their displacement limit, more than twice is power you can't make use of anyway. [/quote] Does it mean that when we're talking about the cab of 600 Watts - the amp of 900 Watts is appropriate or the other way around - the amp of around 300 Watts? I'm sorry - I'm really bad with it as you can see.

Sorry for adding to it as it might be a bit off topic, but I'm about to buy a head tomorrow and I'm also looking at Ampeg, but I'm a bit worried as after doing a lot of research (literally hours online) I've come to a conclusion that Apmeg is not really that reliable anymore. Many people had problems with them and I want something that won't give up on me soon after purchase. My choices are between SVT 4 Pro and SVT 7 Pro - I'm also considering the Galliern Krueger 1001RB. I'm going to be using it mainly for a heavy sound but also some funk. Any advice?

Hi everyone, I'm new to this forum and I was wondering if someone could help me out. Basicaly, tomorrow I'm planning to purchase a new amp, but I want it to work with my existing cabinet : Carvin RL410T (here's the datasheet of this specific model: http://www.carvinguitars.com/manuals/RL410T_Datasheet.pdf). The amps I'm planning to test are: - Ampeg SVT 4 Pro (http://www.ampeg.com/pdf/SVT4PRO.pdf) - Ampeg SVT 7 Pro (http://www.ampeg.com/products/pro/svt7pro/pdf/sw0787_revb.pdf) - Gallien Krueger 1001RB (http://www.gallien-krueger.com/manuals/1001RB-II_700RB-II.pdf) I haven't got a great knowlege in amp sector, even though I was playing bass for many years I'm more of the power switch and volume guy. The cab has a power handling of 600 watts and nominal impedance of 8 ohms and i just want to make sure that whatever amp I'll choose, will work well with it. Obviously with the time I might consider upgrading the cab, but for the time being that's not on the menu. What I specifically don't understand is the RMS wattage. Taking the example of SVT 4 Pro, which has 350W rms @ 8 ohms on the power amp A and B. Does that mean that I will be able to use it with the Carvin cab and will I only get 350W of power or - is this going to be too much for the cab? As I said - I'm really new to all this and woud appreciate some help if possible. Thanks. Sebastian
