But then again, one could also just easily invest in opamps that are only a tiny bit more expensive, but improve by miles in performance. Mar 20, 2021 · To me it seems like the LM358 is a worthy candidate now for many projects even in audio. It clearly is not suited to high quality audio use and should be avoided whenever possible. Lower voltage and increase resistance? Nov 12, 2004 · someone correct me if i'm wrong, but i think that is just a standard dual opamp.

LM833: another higher quality op amp, from my experience a bit more hifi and clear compared to let's say a TL072. , it's not uncommon to see a load resistor across the output so the device functions in Class-A, and this greatly cleans up the major harmonic defect, and ultimately, there are still far superior and cheap choices for general audio needs. LM358: typically thought of as a high gain, low quality op amp. It is in the Lab Notebook. The harmonic distortion of the 4558 and 5532 are below -100 db and are inaudible, while the the LM358 distortion is high enough to be heard by most users.

New 7 Feb 2019 Depleted 9v Batteries. New 10 Feb 2019 Convert a 9v power source to an isolated output for less hum and noise. in HM2 clones it gives a less honky tone and it's also used in the Ibanez WH1. These devices consist of two independent, high-gain, frequency-compensated operational amplifiers designed to operate from a single supply over a wide range of voltages. I would say about 65-75% of distortion pedals have a dual-op amp in them, and they are almost entirely interchangeable (some may require additional caps to help with stability, etc).

However, this opamp has some useful characteristics, and it's very low power, which may well be just what you need. Just a heads-up, LM358 aren't great for audio purposes because they have a lot of crossover distortion. useable in most pedals from tubescreamers to opamp big muffs or phase 90's pretty much anything that requires a dual. JHS uses it in the Angry The low power and low voltage specs also mean this chip has worse noise and distortion performance than others, but these factors are often of no consequence in a guitar pedal. pnbrg ufsk dbez wtxrhjf hvqeoa gxhjg gpdlw wipwyz zef zpthhrs
