Just sold my Brake Lite on Monday and got an Air Brake today. It's waiting for me at home. After work, I'm going to fire up my new Z-28 and SHRED without my neighbors having a clue. At least that's the plan. I'll update you later.
Your pal, Tyler from Everett

The Bedroom setting sounds so good that I've actually gigged my Z Wreck on it. Perfect example of too much amp for too small a place, but I wanted to experiment and it sounded great.

First impressions:
I think my Brake Lite had more defined "steps" than my Air Brake. I bought it used so maybe this has been adjusted. I opened it up and adjusted the rings a bit. Seems a bit more evenly spaced out. I marked the locations before I moved it. Anyone else doing this? What have your experiences been?
The bedroom setting is nice, but a little brittle/fizzy when you get past 12:00. Anyone doing anything to make this better? Maybe it's just me.
Always tinkering, Tyler from Everett.

I remember adjusting my air brake years ago to increase the difference in the last couple of steps. All attenuators get a little wonky at max attenuation, the air brake is amoung the better ones though. I use a power station for extreme attenuation on high powered amps. But, with Docs new master volume the attenuators aren’t seeing much action these days.

Every amp sounds a little fizzy when overdriven at low volumes....I think it’s because the speaker isn’t working much...so not a lot of air being pushed. Tone isn’t just in the fingers i guess after all.....some of it is in the speaker pushing air.

That fizziness the Air Brake on max atten/max bedroom is why i ended up with the Ox. At our jam band rehearsal, we're headphones. I was the only one making noise with my amp/speaker with the Air Brake on max. It served me well for years, but I figured it was time to try something new. I tried to mess with a little EQ'ing to tune it up, but you're right above that it's just not the same as a speaker pushing some air. Through my various experiments, I pulled together the attached graph. You can see at max attenuation you start to lose some low end and gain top end which results in the fizziness. I was surprised at the loss of low end, but I suppose that makes sense. This was all done using my Ghia into my Air Brake into my IsoCab with a Greenback at home. The graph below is all with my Air Brake. The blue line is zero attenuation. Green is 4 dB on the Air Brake. The orange is max attenuation with bedroom turned to max. A little attenuation changes things a little bit. But, after thinking about it. The trade off is to drop the master on the amp and lose tone or push the master up to get the tone you want and back off on the air brake. Option 2 pushing that amp wins every time. And, my ears were always happy even the graph says there's a difference.

Very cool analysis. I would have expected loss in the high frequencies. This was with the Ox, correct?

That was all with my Air Brake. I edited my post to be a bit more clear. I can't remember if I did the same test with the Ox's attenuator. I don't think I did. I've been curious if the freq responses are simply the speaker's reaction relative to power or if impedance plays a role as you crank in attenuation or what. It did hit me that if a speaker is getting hit with a Ghia wide open at 18 watts, it will probably react differently when you knock that signal down to something less than a watt.

I would assume that below a certain power level the speaker is simply not moving enough to generate the lower frequencies.

How's the airbrake? I'd like to hear how it worked out. Jeff

How's the airbrake? I'd like to hear how it worked out. Jeff It has been great so far. I’ve played one show with it, at the tractor in Seattle. It was nice, the sound person appreciated it. My band mates appreciate it too, so I’m not blasting them at rehearsal. I still think I’m going to send in my Maz Jr for the mkii update. I’ll use the air brake for my z28. In regards to tone suck, it’s minimal if at all until you get to the bedroom setting. In opinion, at least. I’m still getting used to my Z’s. I’m moving from a 71 DR and a 74 Princeton Reverb. My Z’s are much louder, and much more full sounding. I’m very happy.

Such a simple, well built, effective tool!
