i just have a little question,
whats the peak voltage an electric guitar can output?
isnt that something important to consider
when building a pre-amp ??
Maybe this forum should have a FAQ for stuff like this. Search (ssguitar) function is quite helpful tool, by the way: There was some related discussion maybe about a week ago.
Anyway, the short answer to your question is: Nominally anything between 10 - 200 mV depending on the pickup and guitar's internal electronics. Crate, for example, seems to design their amps based on 40mV peak-to-peak value. However, the maximum output amplitude of a "hot" pickup can be as much as few volts when strings are strummed hard. However, this value represents a momentary peak and the output amplitude settles to the nominal value rather quickly.
Some manufacturers list the output amplitude of their pickups so you could search that information for reference. I posted a link to some pickup "datasheets" maybe a year or two ago. You can find the thread if you search.
thnks for the info.
lookslike the best deal is to design a preamp with a pot to adjust the gain.
