Built Hornet pedal - still need help.

I have questions about the Hornet.

1) What does the 500K pot control?  (It seems to only control volume.)

2) Is it a problem if I use a 1mh pot instead of the 500K pot?  

3) Can I add something to the circuit to make it act like a 500K pot?  

4) What does the 5k ohm pot do? (It seems to control the distortion/fuzz)

5) The pot I have for the 98.2k pot maxes out at 95K or 96K.  Will it make a difference?

6) The sustain doesn't sound quite right.  Is there a way I can adjust it?

7) Can I damage anything by adjusting the other trim pots?

8) Can anyone give me links to sound files so I can tell what it should sound like?

1) What does the 500K pot control?  (It seems to only control volume.)
 Its a variable voltage divider, or output volume control pot.

2) Is it a problem if I use a 1mh pot instead of the 500K pot?
 Probably not, put a 1 meg resistor across volpot lugs 1 and 3 to see what the differences are...[two 1 meg resistors parallel = 500k]  

3) Can I add something to the circuit to make it act like a 500K pot?  
 ...^

4) What does the 5k ohm pot do? (It seems to control the distortion/fuzz)
 Variable Resistor gain control...yupp.

5) The pot I have for the 98.2k pot maxes out at 95K or 96K.  Will it make a difference?
 Imperceptibly, probably...use a 100k pot [marked 100k may measure 87k or so...] and adjust it, this just shows the measured resistance of the pot setting Aron had there ... you can measure the collector voltage, and move it up or down...most people like the Q2C of FF to be around 1/2v or 4.5v of 9v supply, or set by ear/

6) The sustain doesn't sound quite right.  Is there a way I can adjust it?
 Try adjusting the bias [pot marked 98.2k].

7) Can I damage anything by adjusting the other trim pots?
 Probably not...I have, but with  circuit error.

Can anyone give me links to sound files so I can tell what it should sound like?
 Should sound heavily distorted like the FF it is...schemtext mentions sustain.
 Different transistors will make it sound and bias differently, the circuit should be adjusted to bias the transistors.
