What is Gating? How does it sound like?

Anybody?

[Zero the hero]

Did you mean noise gate?
They automatically turn all the way down the volume when you're not playing. This avoids hum and hiss when you're not playing your axe: the gate is closed.
Then the volume raises when the input goes above the trigger level, so when you're playing the gate is open and this doesn't affect the sound.

Gating is an abrupt cut in the sound while the sound is on it's way to decay (or fading out). Or sometimes, just anywhere in the duration of the sound. It can also be a intermittent cut in the sound as it decays.

When you hear that a note is cut short when you think it should last more (sustain), that's gating.

Is it only the transistors thats causing it?
Whats the remedy? I'm having that kind of problems with my
compressor builds.

[zener]

Misbiased transistors is one cause for gating. It can be caused virtually by anything, loose wires, bad solder joints, shorting blah, blah, blah.

Is that a Ross compressor?

What transistors did you use? If you have a multimeter, check the dc voltages on every pins of the transistors and post it here. There are many knowledgeable people here (except me :lol: ) who can help you.

You can also try the audio probe and find where in the circuit the gating starts.

Gating can be useful, it stops bad distortion pedals from feeding back maddly when not it use. For what you have here it is not really useful. As Zener said, just use an audio probe/sig. generator and osciliscope to find out where this occurs. Replace the bias resistors with pots? and did you sub any components from the original schematic (transistors,resistors, etc...)

If it;s a Ross/Dyna Clone on PCB, I would first redouble your triple checking efforts with regard to transistor and OA orientation.
 If it's an OS clone on perf,...that's another matter for future post.
 What's the circuit??? In any Case...doing the probing, regardless of the circuit, should help isolate the problem...once that's done, it's  the hard or easy part.L..find ing the solution.
