Amps with built-in attenuators or variable output wattage

metalfiend666 · 12-05-2006, 05:16 AM

A rough rule of thumb is 10 times the power = 2 times the volume, ie an amp pushing out 100W is twice as loud as an amp pushing 10W. Obviously there's not such thing as a lossless circuit and things like cab and speaker choice have an effect, so it's only a rough rule.

the other amps that have a built in attenuator are the metaltronix head and one of the older laneys. there used to be an ad with paul gilbert that read something like it uses up tubes faster but who cares.

I don't think they make them (Metaltronix) anymore.
But they sure have funny vintage ads on their web page.

Would you recall what model # or name the Laney one is?

How does that sound @ low volume?

This line of development directly lead to the power switching options in the Road King. Progressive linkage (the ability to mix and match disparate power tubes) was the finally piece in the puzzle, really.

i don't remember the model of the laney.
a big part of the attenuators is that i think you need the speakers to work more to get "that" sound. so by using the master, you get more saturation, but not the total cranked guitar sound. if that makes any sense.

I for one cannot wait to try out the ORANGE Thunderverb at NAMM 2007 this is a hit list for me..and i hope to bring one home with me....but THD Plex and Uni Valve both have a ATTN: built in...I have a 8 ohmn THD Hotplate "purple one" that works great at lowering the volume of my Tri amp & Brunetti and makes the tone more saturated for lower volumes...I tried the Hotplate with the Mesa Road King and it sucked the life out of it...i think the road king is one of those amps that just needs to be left alone....

They're seriously naming an amp 'Thinderverb'?

What does that mean? Does it have something to do with Thiele cabinets or something like that?

Jerich · 12-09-2006, 08:46 AM

sorry THUNDERVERB!!!

The Dark Wolf · 12-09-2006, 09:03 AM

Thunderverb! Oh, ok!

That makes a hell of a lot more sense, doesn't it? I thought Orange was seriously off their rocker or something.

That Thunderverb really seems to be the shit. 200 watts of megalomania.
Too bad it's like 1 849 989$.
I want that built-in attenuator.

Thanks for the THD Plex + Uni valve info!
