Anyone actually understand the Gallien Krueger on-board limiter?

[goonieman]

I'm the proud owner of a GK MB150E-III head. Great fun - with loadsa knobs and tweakability.

However, I can't - for the life of me - figure out this dang limiter control. I can't hear any squishiness when engaged, or anything for that matter.

I presume its designed as some kind of safety precaution to protect from overloads. It will act like a limiter should presumably, i.e. cutting or affecting major peak transients.

Personally, I can't get it to do anything (i'm mainly using headphones at the moment - maybe that's why? maybe the limiter doesn't route through to the headphone jack? I dunno....)

Anyone have hands-on experience? thx

Just looked at the manual. The limiter comes after the headphone section and only affects the power amp output. It is a actually more like a power scaling circuit, not a peak limiter per se BTW.

Here's the User Manual, which explains all ...

Only useful (if at all..?) with a cab, it reduces the amp power o/p from 150w to about 20w, progressively. Should be fully clockwise most of the time, unless you hear distortion. Hmm...

thanks guys.

Yeah, I read the manual. Didn't help me much.

Maybe keep it somewhere halfway, just to be safe, at all times?

As the manual says keep it fully tumed up if you don't hear distortion, turn it down if you do. Don't expect to hear a massive difference in volume. There's surprisingly not that much difference between 20w and 150w; subjectively 150w isn't even twice as loud as 20w, let alone 7.5 times as loud.

This ^^^^

Leave it fully clockwise by default.
