Kevin Dean Posted May 11, 2014 Share Posted May 11, 2014 I use a Barefaced super 12T , I also have a MarkBass Mo Mark 250 (250watts) & a Little Mark Rocker (500Watts) . just out of interest with either of them on exactly the same volume setting they both give out the same volume . How does that work ? Quote Link to comment Share on other sites More sharing options...
Davebassics Posted May 11, 2014 Share Posted May 11, 2014 Volume controls are logarithmic so the first steps have a much greater affect on "Volume" than the later steps. I guess that would mean in the initial stages of 2 different amplifiers, both are closer than they would be towards the end of the taper. The taper on the pot and the efficiency of the amp can also be a factor on the signal leaving the amplifier. Another thing to consider is your definition of "Volume". I think your referring to "perceived loudness" which is a whole other ball game. But yes I agree, you wouldn't expect 2 amplifiers by the same manufacturer to sound the same given the identical settings and different wattage.

hamfist Posted May 12, 2014 Share Posted May 12, 2014 Effectively what Dave (above) has said. Slightly different tapers on the volume pots would account or it. PLUS ..... 250 to 500 watts isn't really that much of a difference in perceived volume. My question would be .....does the 500W amp continue to get louder at the same rate as the 25oW one as you turn the master volume up ? I would expect the 500W to "keep going" when the 250 Watter runs out of steam. Quote Link to comment Share on other sites More sharing options...
brensabre79 Posted May 12, 2014 Share Posted May 12, 2014 Also, dont forget that double power doesnt equal double volume... Quote Link to comment Share on other sites More sharing options...
Davebassics Posted May 12, 2014 Share Posted May 12, 2014 Does your 500W get hotter/Drive the fans more? Anything that isn't converted to compressed/decompressed air is wasted wattage. Quote Link to comment Share on other sites More sharing options...
Kevin Dean Posted May 13, 2014 Author Share Posted May 13, 2014 That must be it ,I only have the volume at the 9 o clock for it to be loud enough for my band . Quote Link to comment Share on other sites More sharing options...
Subthumper Posted May 24, 2014 Share Posted May 24, 2014 Join a louder band and then see which amp cuts it best. Quote Link to comment Share on other sites More sharing options...
Kevin Dean Posted June 10, 2014 Author Share Posted June 10, 2014 I spent a bit of time doing an A/B test on these heads & even though the volumes are the roughly the same the Little Rocker has a lot more low end thud to the sound that I just can't get with the other amp , does that make any sense ?

Just unused in a particular situation.There's no such thing as wasted when it comes to headroom Quote Link to comment Share on other sites More sharing options...
