The poll's pretty self-explanatory. I thought that I would put options for both solid-state and tube amps, because they are apples and oranges in the world of guitar rigs and how the amp reacts.
Also, if you don't mind, could you also post the cabinets that you are using, and if possible, speaker efficiency, since cone area has a big effect on volume? If you use a stereo amp but only use one side, just base your answer on that. If you run it in stereo or in bridge mode, then answer based on that. Base amp's output on the impedance load that you normally run rather than an amp's output at its lowest rated impedance level. If you use more than one amp on a regular basis, then feel free to vote more than once.
If any of my data points don't seem good, let me know. I tried to keep two things in mind coming up with them: 1. Typical wattage ratings for most major amps 2. The law of diminishing returns on how many watts you're running.
p.s. After making this poll, I really envy how you guitar players don't need a dumptruck full of watts for headroom. 50 screaming guitar watts would barely move a bass speaker. LOL
