Resistors damaged? Help...

[Spyfly]

I was trying to build the EHX Hog's Foot bass boost on a piece of wood for a DIY guitar amp as an internal device.
I used 3-5 resistors (from a TV and a JVC Boom Blaster) in series to get the desired resistances. I built a power supply i thought was about 9V, but it actually read 20V.
Now all the resistors make no numbers on my meter. The output is extremely low and when i turn the pot i can still hear the bass boost, but beneath a giant hiss as i increase the volume.
Is it possible that the problem is the 20 volts, or could it be something else?
The transistor is a 2N3904.

So what does it say? Letters? "Err"? "Over"? "---"?

Lick your finger, put the ohm-meter  probes a little apart. What is the reading? Should be 5K-500K depending on skin and sweat.... this verifies your meter is not dead or mis-set.

Are there any Volts at the transistor legs?

You "can" buy resistors. I agree about $13 shipping on a $1 order.

  Cause to suspect the meter is not reading resistance for some reason, all resistors are probably good...set up a voltage test for the meter [measure a battery] and a resistive divider, see if two equal value resistors divide voltage equally [you should see 4.5v at the junction of two = value resistors..in series across the 9v supply.
   ...spare meter...I have a few ! [check the battery in the meter]
