I had to replace a 500k alpha linear pot recently on an amp just before a gig, and only had a 1M log PEC pot lying around. the amp seems to be considerably louder but isn't exactly the same tone, seems more of everything...volume isnt the only thing, the transition to overdrive is definitely quicker and the amp seems to have less headroom before getting all farty. I know the tapers are different, but it just seems like the amp has more of everything. Was this to be expected? I tried to google relationships between volume pots and amp tone and gain structure but nothing helpful. I'm well aware of pot values and tone in guitars, but not in amps...Any tech heads care to chime in?
