# Brown-Bier Theorem

### Brown's Theorem

`Q = 1 / k`

The quality of an amp is inversely proportional to the number of knobs it has.

Following the pioneering work of Greg in this field, Stephen proposed the following postulate in late 2006:

The quality of an amp is proportional to t, the percentage of the amplification done by vacuum tubes rather than transistors.

### The Brown-Bier Grand Unified Theorem of Tonal Quality in Amplifiers:

`Q = t / k`

### Gear that Gets It

Does anyone else find it funny that if you say Brown-Bier Grand Unified Theorem out loud it sounds like "Brown beer"? Ah, good old the Near/Square merger :D --- christina

Not really, Bier is the Dutch and German word for Beer so its hardly surprising --- brehaut

May I also add that I am actually part of a musical duo that writes songs, and we have taken our band name from our surnames - Browne Bier --- stephen

Greg suggested that the index may need to take into account multiple channels, and whether they are switchable --- brehaut

Yeah... maybe Q = t / kc where c = number of channels? --- greg

I feel that we should redefine "k" as the number of knobs that do not have "11" as a maximum possible value. --- angus.

I propose the following amendment:

`Q = e ? (negative infinity) : (t / k)`

where e = number of knobs that go to 11
