it's a resistor network (called l-pad) which is connected between amp output and speaker cab. it absorbs part of the power which goes to the speaker allowing you to crank your amp and have moderate volume
MuSician is correct. Also, tube amps sound best when they are cranked and the tubes cookin. To do this, your amp would be really loud and your band would look at you funny. So the Airbrake/Brakelite absorb some of the power so the speaker receives less power thus resulting in less volume. Your amp doesn't know the difference. To get "Gain & distortion" that everyone playing rock and roll loves, there are 3 basic areas it comes from.
1 - Pre amp distortion. That is when you overload the small pre amp tubes with signal. This is done by boosting your input signal. This distortion can sound "Fizzy" a bit.
2 - Power amp distortion - This is when you overload your output tubes with signal. This is done by cranking an amp. The distortion is very powerful and punchy. I prefer power amp distortion to pre amp. Think AC/DC sound, etc.
3 - Speaker breakup - The speaker being overdrven can also contribute to your distorted signal. Depending on the type of speaker you use, it can break up and color your sound as well. A 30 watt amp into a 60 watt speaker won't break up much, if at all. A 30 watt amp into a 30 watt cabinet will probably cause the speakers to break up a bit at higher volumes. Some guys like this sound, some do not. Using an Airbrake, you probably won't get speaker breakup since you aren't sending as much power to the speakers.
Your distorted sound is a combination of these 3 types of distortion. Being aware of them allows you to mix them to get your desired sound. Good luck!
Jaguarguy (Mike): Hey Gary - Joe Walsh used a G12 65 in his Galaxie and it sounds great!

GuitarZ: So, I cranked up the privacy protection on my browsers, facebook, etc. I have to say I miss the music ads and such. I really don't need ads for watches and other random stuff. Maybe the internet knowing me isn't such a bad thing.

Joey Beverages: hayesgary307 try a Z 210 or Z 410 with Galaxie ... also, yes the G1265 is most tasty and excellent

GuitarZ: Reminds me of buying my Honda. When they tried to sell me the maintenance package, I said "Is your car not reliable?" Long story short my wife teamed up with the sales lady to buy the maint package. Never again!
