im trying to make an analog effects pedal. specifically a delay pedal. so iv bought two tape player/recorder's. i need to make a preamplifier, although i have made valve amps and pre amplifiers before with op amps iv never had to amplify such a small signal. i think the signal is around 1µv. any suggestions would be appreciated!
To change the delay time im going to have one of the two heads adjustable to make the distance between the heads longer. with the cheapo recorders i go the erase head is just a magnet. i am also thinking of making it so that i can use the tape in the forward and backward direction but this would complicate things and i think i would need to mechanically move the eraser head.
does anyone have any ideas on the voltage going to a recording head??
thanks!!!
