    I am curious. I can see that the 4500 is the SAME amp with more wattage, but I'm wondering how much more wattage? Just how much difference does that extra 150 watts make?
    I have a 3000, and I'm underpowered into a 4 ohm 2x15 cab. My old Bassman 135 used to push harder.
    Since the introductory 4500 price is even cheaper than I paid for my 3000, I'm checking into a possible upgrade.


  2. As I understand it, the relationship of wattage and volume is not linear but exponential. To gain a noticeable increase of 3db you would have to double your 300watts to 600 to get another 3db would require 1200watts. So upgrading a 300 watt amp to a 450 watt amp would, most likely, not even be an audible difference. Hope that helps to answer your question.

    There's got to be more to it than that. There's also resistance and impedence and all that crap that I have no clue about. Jimmy will clear it up for you. He knows everything.
  4. Well certainly if you are running your 300 watts rated at 4 ohms through an 8 ohm or more cab, that will cause less volume because you will be limiting your available power. I am assuming you are running at peak impedence as it is. All I was saying is jumping from 300w to 450w is not a large enough jump to warrant the upgrade (read as $). I would recommend 600w or more.

    Thanks for the replies. I was curious as to how much (if any) differences there would be between the two amps. I'm in need of more headroom, but I'm not in the position to buy a completely new bass head.
    I've been looking into using my head to preamp out to a power amp for extra wattage and versatility.

  6. if you are already under powered, and are running your amp at its max, yes, you will see a slight advantage... your amp will push a bit harder before distorting (ie. more clean headroom, but 150watts is pretty negligable as far as headroom goes...). So you could probably run at the same volume you are doing now, but it would be slightly cleaner and would probably be kinder on your speakers as well...

    consider switching brands, though. I had the 3000 and I thought it did an okay job, then I switched to an SWR 350x and I could not believe how drastic the difference was. It sounded louder, it was a lot cleaner sounding, the tone was better. The mids growled more, the highs were crisp, the lows were smooth and not muddy.

    The berhinger stuff definitely serves a purpose, but I think you've surpassed that purpose. It is definitely worth the money to save up a little longer and switch brands. Also, don't get too caught up on the watts rating. like I said, the 350x sounded a lot louder than the B, but it was only 50 watts more. let your ears be the judge. explorer the 2nd hand market. it's worth it.
