What is Negative Feedback?

In this video, we explore negative feedback and its role in shaping the sound of an amplifier. We discuss how it works and then provide A/B playing samples of different negative feedback values.

Nice! I didn't realize negative feedback was that involved, figured it more to be a kind of low cut or dynamic control but didn't know how or why. Cheers :)

Check back next week - You might be interested in a video I'll be releasing that talks about presence and resonance and how they work (hint - they work hand in hand with the NFB loop.)

With the guitar, amp and mics set up in your demo, less negative feedback wins.

[@sonictoneamps]

Yep - I tend to usually play with the less negative feedback setting myself. I personally like the more aggressive tone.

Thanks - great info 🤘

You forgot the pickup switch in the central position at 3:57 (smooth setting), so it’s not comparable to the following clip, which is played with the bridge humbucker only. Anyway, thanks for the comparison!

Both sound very muddy.

😂 sounded peavey ish

[@truescotsman4103]

negative feedback is being heckled by the audience when you suck.

U should try digging in rather than just strumming shit. More NFB gives more traction but limits immediacy, less is more explosive. Without control of the left hand u can't really notice anything. Good try though
