After my last post (thank you everybody who replied, you were all more than helpful!) I built the Brian May Treble Booster. 

I used a BC182L measuring approximately 330 hfe. 

I left in the 1k resistor and used a 10k pot for the collector resistor instead of the 6.8k resistor.

I was a bit nervous when the collector measured 8 volts with a 8.89 volt battery...Makes me wonder how it would have been with the 6.8k resistor. 

However, it fired up first try and sounded really good. 

I found the boost to be pleasant and the treble definitely cut through a bit.  However, the low end didn't seem as attenuated (for better or for worse) as with the Rangemaster. 

I was also pleased at how little the pot crackled.  I understand that due to DC voltages being on the pot, it will crackle a bit.  I expected a lot more noise than it actually produced though. 

As for hiss or hum, no hum, and about the same amount of hiss as my Rangemaster.  Nothing ridiculous. 

Once again, thanks to everybody who gave me suggestions last night!
