Manufacturer = Texas Instruments Series = TL072. So for the output amp the peak current with 1K / 9K resistors will be 1 mA with an average of about 0. Voltage Gain of Large Signal is 200 V/mV The rejection ratio of Voltage Supply is 86 dB Equivalent TL074 Op-Amp isvLM324, TL072 & TL071 whereas alternative op-amps are LM748, LM741C, LM741A, LM709C, MC1439 & LM201 LF351 TL072 - TL072A - TL072B 3/10 ELECTRICAL CHARACTERISTICS V CC = + 15V, T amb = +25 5C (unless otherwise specified) Symbol Parameter TL072I,M,AC,AI,AM, BC,BI,BM TL072C Unit Min. features high slew rates, low input bias and offset current, and low. Re: Guitar preamp op amp tl072 input noise.If you need more bandwidth, take a look at LT1057's by Linear Technology. Use an MC34071 single, MC34072 dual or MC34074 quad high speed opamp that also has a minimum supply voltage of only 3V. Noise gain is the gain seen by a noise source (input voltage noise) or voltage source (input offset voltage) connected in series with an op amp input.

Amplification is carried out by two separate stages to ensure a better stability and bandwidth when the gain is at its maximum. Then the "0V" of your output could be - 1. The devices feature high slew rates, low input. The audio input is attenuated with a potentiometer of 10k – creating the volume. TMIN≦TA≦MAX 70 dB Supply Current ICC No load TA=25 C 1. The TL072 doen't meet its spec's when its supply voltage is lower than 7V.Wide common-mode (up to V CC +) and differential voltage range.The device features high slew rates, low input bias and offset current, and low offset voltage temperature coefficient. 7k is a reasonable starting point, then go from there.

You should try to gain a fundamental understanding of how an op-amp works and how to calculate the gain, then it will be easy to figure that part out.
