@@pramesh.gurung the Audient. It’s only when running the di box into the mic pre. There’s no noise when running straight into the instrument input, however the input impedance is only 500k, which is a little muddy and lacks clarity.
It's the natural sound my Audio Interface makes combined with the fact that this amp is moddled after one of the loudest filthiest amps there are which makes it hard to tame but insanely rewarding if you do.
Sorry for the late reply. I tend to fix my issues by looking for potential sound sources in my signal chain. For my example the 48V phantom voltage caused so much noise that my playing was sometimes quieter than the hiss. The amp this one is modeled after is just a very filthy loud beast to tame and such you have to make sure you don't feed it with too much stuff it's not suppose to amplify. I hope this helped let me know if you need more help :)
