[quote name='Zach' post='822735' date='Apr 29 2010, 09:47 AM']considering the rule of having to 10x the power to double the volume, power to volume is an exponential relationship, and therefore to stop your pot turning output also being exponential, you need the pot to be logarithmic to transform pot angle Vs output into a relationship that's closer to linear.
hooray for A-level maths, lets just hope i've remembered it correctly.
Edit: have thought of it more properly, you start of with something like 10^p=k.V, where p is power and V is volume, with k being some constant, and using log pots changes that to p=log(kV), so your response graph goes from [url="http://hotmath.com/images/gt/lessons/genericalg1/exponential_graph.gif"]exponentional[/url] to[url="http://people.richland.edu/james/lecture/m116/logs/logarithmic.gif"] logarithmic[/url], which is just a bit nicer.[/quote]
Great - it makes perfect sense now! I will try log volumes and lin tone and see how it goes.
Thanks for helping out.
