I get these days every so often where i just don't like my guitar tone. Sometimes it's immediately cured by changing amp (i have a handful), or boost pedal. Most of the time i wait till the next day and everything is fine again. Tonight i had a really extreme one where everything i heard sounded nasal to me. I changed through all my amps, my two cabs, all my boost pedals, spent ages dialing in all sorts of of tones, and i just couldn't stop hearing a small hint of a nasal sound and hating it (even though most guitar tones have it to some degree). What was weird about this evening is that my normal bad tone day isn't usually focussed on something so specific as a nasal aspect to it. Anyone else have times like that? And have you come up with a good reason for it other than being in a weird mood or state of mind? I was actually really physically tired, so maybe that had something to do with it.
