Volume output question (Dead End FX Spectrum)

[fuzz]

Hi All,
I'm still learning so I was hoping someone could look at this schematic of the Dead End FX Spectrum and tell me if there is a resistor(s) that effect the overall output of volume. As is, in order to get unity gain, I am roughly 90% up on the Volume knob. I was hoping to get a bit (not too much tho) more runway for the volume output.

Thanks all

R20, r13, r18 seem like the most obvious places to me. Maybe check they are the right value. You could reduce the value and this would make it larger.

R18 is 100k. You could solder another 100k in parallel with this and it would bring it down to 50k. Should be louder

You could also increase the value of the Volume pot to 100k and add a 10k resistor between lug 1 and ground
