somewhat of a theoretical question that may proof to be practical...
Can two air/brake/lites be run in series?

I thought about this for a while... and fundamentally or theoretically, this should work just fine. So I tried it and sure enough it works. Without the 'bedroom' setting of the airbrake... the brakelite is arguably not quite quiet enough for for practicing at home in my condo. So I may not be able to move away from the full airbrake... but I will be able to leave it at home (the brake lites will work fine playing out, even with the very loud R66).
So FWIW... I hooked the two brake lites in series... and was able to get a very nice lush tone from my Ghia at 11pm bedroom levels. I think I had both set on 3.

Mark, So I take it you have both Airbrake and Brakelite? Would you say the Airbrake does more then the Brake Lite?
I use the attenuator on the Mini with the Brakelite and it works fine.
I find the Brake lite marginally acceptable to do the job with my Ghia without my wife getting on me. Wondering if I would be better off with Airbrake.

Hey Buddy...
I did not do an A/B test to find the answer to your questions specifically... but here is my overall impression. The brakelite lacks the bedroom setting and micro adjustment of the airbrake... so the airbrake will go lower. That said... I think the tone of two brakelites... is not substantially different than the bedroom setting... which is not great... but better than turning down the guitar or amp. My ears and gut tell me that the more I attenuate... the more it sucks tone.
The alternative (have not tried the weber or ultimate attenuator) would be the fluxtone. It varies the efficiency of the speaker to get closer to what we are all after at low volume... but at 850 for a speaker... its a little pricey.

Is this safe (for the amp)? Do you need to set the ohms switch differently or use a different ohms output jack? I have asked before about using two attenuators in parallel and the answer was a big no, but maybe in series is different.

I have asked before about using two attenuators in parallel and the answer was a big no, but maybe in series is different. Not sure the benefit of putting them in parallel. You would have two units doing the same thing, to a spit signal path, for separate sets of speakers? I would thing you would just split the path after the attenuator. Looking inside of the units, the primary difference seems to be the number or size of resistors (which would seem to be why the airbrake can handle more wattage). So putting them in series just gives you more overall potential resistance... and more stops along the way. But I am not an electrical engineer... or an amp tech.

do not put in paralell, this will divide the attenuation. in series it takes sense because you add the attenuation of both. any combination will not affect the impedance (ohms) in a matter of concern.
