I'lll add another +1 for the pf 500. Great amp and flexible wrt speakers. (As long as no lower than 4 ohm total.) Sounds good with the pf 115, and IMO, maybe even better with my Avatar B212 (tweeter turned off in both cases).

Regarding Ampeg

Okay, I'm really unsure on ohms and stuff (I DID read the sticky on it, but I got really confused
). Would I be right in saying, with a 4 Ohm head, I can either run 1 4 Ohm cab through it, or (2) 8 ohm cabs, to the same effect? Also, I think that's going to be out of my price range 
At the moment, I'm only playing small, indoor gigs and the biggest gig I've played, there was a Marshall bass amp (possibly 4x8) provided.I'm sorry man, I've literally no clue what you're on about
what is Neutrik? (that's not the only thing I don't understand, that's just something mentioned which I don't have a clue about)
Why not?
If I was to buy This, it says it's RMS Power Output for 4 ohms is 450 Watts. I don't know what RMS means
help but does that mean, if I use a cab with a 4 ohm inpedance, the maximum that cab could be is 450W (or more than one 4 ohm cab who's total (all added together) impedence is 450W maximum)?
Because one of those cabs is 8 ohms and the other is 4 ohms, which will give you 2.67 ohms, and that head will only go down to 4 ohms. You need to find two 8 ohm cabinets, which will give you 4 ohms.Why not?
If I was to buy This, it says it's RMS Power Output for 4 ohms is 450 Watts. I don't know what RMS means
You can't use more than one 4 ohm cab with that head.
Right so, if I was to get that head, it would make sense to get an 8 ohm cab, so, if that wasn't cutting it, I could get another 8 ohm and run them both through that head?
Also:

EDIT: that should read or more than one cab who's total impedence is 4 ohm (E.G. two 8ohms) and who's total output is 450W?
Yes, however, the head will be running at 250 watts through a single 8 ohm cabinet.
I'm sorry, but I'm not making much sense of this question. Impedance is not measured in watts, and you can't run more than one 4 ohm cabinet with that head.
The head wouldn't make the cabinet(s) 450 watts. The cabinet(s) is whatever it is rated for. The head could send 450 watts to it/them.
Yes, however, the head will be running at 250 watts through a single 8 ohm cabinet.

What does that mean? I get what is happening technically, but is that a problem or is that fine or what?
Yes, sorry mate, I editted that one, I've not slept in 2 nights, so I'm a bit careless haha.
Ps: thanks a lot for taking the time to explain all this to me, I understand that it's probably very frustrating with me going 'huh?' at everything you say, but I am learning! Thanks!
If you are asking if it will harm the head or the cabinet, no, it will not. In that respect it is no problem.
If you are asking if that is loud enough, it depends on your needs. If it were me, I would go with 8 ohm cabinets.
You're welcome, and don't worry about it, man. We've all been there.Yes, sorry mate, I editted that one, I've not slept in 2 nights, so I'm a bit careless haha.

Wannaflea: If an amp is rated at 500 watts it is usually rated at the maximum load of the amp, typically 4 ohms. It will run at 8 ohms as well but it won't put out as many watts. An example is the Ampeg PF-500. It is rated at 500 watts at 4 ohms or 300 watts at 8 ohms. If you use one 8 ohm cabinet with it it will put out 300 watts. If you use two 8 ohm cabinets or one 4 ohm cabinet it will put out 500 watts.
There are a few amps such as the Carvin BX500 that will go to 2 ohms. In that case you could use two 4 ohm cabinets or one 8 ohm and one 4 ohm together.

I think I was trying to ask both hahaha. I'm playing small (always >500 people) gigs, so that's the size that the amp will have to work with.
Yeah, it's annoying being completely clueless about amps haha. I've got my head screwed on bass wise but with amps it seems to be either a) amps are what make the bass loud! or b) a hellova lotta technical lingo, and there seems to be little inbetween

Amen. I'm dizzy just from reading the FAQ about ohms & etc. Here I thought buying a Fender Rumble was safe and smart.
That's what I got too, a couple weeks back. I was using a god-awful 15W combo that came in a no-brand starter package. The thing 6" deep, maximum. Now I've got my Rumble, it's really let me find exactly what I want, tone wise. Now I can save up and invest in something built specifically to give me that tone. Sorted 
Hi all,
I'm still fairly new to the game here so please excuse my ignorance.
Amp-wise, I'm currently using a Fender Rumble 75W for my home practice. However today, I went to the local studio to do some recording with the band and I used and Ampeg combo. Wasn't very big, I could make out 'B2' (there may have been more but there was a sticker right next to the name on the front). Sweetest sound I've ever heard from my bass. I'm using a Fender Jazz, with DiMarzio DP128's (really dark, punchy pickups) and it sounded so nice! I had brand new strings (GHS Boomer Flea's) on so that will have contributed to it but the highs were glittery, had a round bottom end and it cut through without being winy.
I've done a bit of research and I've found Invalid Link RemovedI'm pretty sure this and the one I played through are one and the same. Problem is, it seems like this model has been discontinued.
Can anybody suggest a similar amp (tone-wise, not size wise) that would get me that sound which I'm now craving... Not satisfied with my Rumble when I got home
Hi WANNAFLEA;
Regarding the B2...
I also have that amp. I bought it new back in 1997 and I've been happy since...with the exception:
It's been tough to play outdoors or medium sized clubs using the combo alone. I've had to run the signal from the amp to the house speaker PA so that the bass could be heard. In my experience, any distance greater than 20 feet from the amp and the sound would die. BUT my band mates got annoyed that I would run my bass through the house PA because it made noise with the vocals (we do A LOT of 3 part harmony). So TODAY I just picked up a second cabinet to add to the B2: it's an Acoustic B2110 (2 X 10) 8 ohm. Adding this to create a rig give me the 1 X 15 (8 ohms) plus the 2 X 10 (8 ohms) for a total of 4 ohms at 350 watts. So far, the sound is AMAZING. I have yet to play it with a full band or in a gig.
If you can find a used B2 combo like you had in the picture, I suggest you pick one up. In this economy, I'm sure there are a lot of people looking to get rid of their equipment.
