Driven amp hiss

[Baz1984]

Hey All!!

I've built an ac30 simulator for recording, but I want to simulate the hiss that the amp produces when up full with a booster in front of it (Think the first few seconds of oasis cigarettes and alcohol)

If I run 2 drive pedals in front of the sim I can get the hiss but there is miles too much gain.

I was thinking of making a white noise generator and using a blend pedal to dial it in to taste.

My questions are;

* Is there a better way of doing this?
* can anyone reccomend a circuit and a way of changing the pitch of the white noise (like its tuneable)

Thanks in advance

Welcome to the forum...

Tried one drive pedal?

1. High gain...

2. Well, you can't exactly pitchshift via analog, probably a looped white noise sample with adjustable sample out rate?
The easy one to do is adjust the frequency content of the white noise. (Basically EQ'ing the noise)

In the recording, the hiss was almost certainly on its own track. A recording of too many idle pedals, or a mistuned radio (Pink Floyd Wish You Were Here), with mixer tone controls for "tone tuning", and faded-in/out to taste.

Thanks for the welcome,

Drive pedal, I use a treble booster.

When I run the same booster into my actual ac30 full up I get the hiss.

Will give it a go and see what happens.
