according to the schematics, a 4mV 1khz sine wave entering the input will give a 66mV output at the preamp out socket. i know my guitars put out a higher voltage than that (i have one that can put out over 2V peaks!) but the preamp output voltage wouldn't increase linearly with that i shouldn't think. i would be very surprised if the output voltage was anything to worry about, as i think the opamp before the plug is designed to drop the voltages down. say what you like about fender, that opamp isn't anything special, so i doubt it would handle much more than your soundcard's line input. i'm pretty sure i have hooked my (now in pieces) one in that way once. like i said in the previous email, it isn't going to replace a 'clean' mic pre, but it should give interesting sounds... wondering now what the 'more drive' settings would have sounded like with my valve mic :) hehe of course usual disclaimers apply :) porl 2008/5/29 Christian Delahousse <christian.delahousse@xxxxxxxxx>: > What is the output level and type of the preamp section?
