Different potentiometer values in schematics 2 channel Dual Rectifier

Hello, I see 2 schematics of the Dual Rectifier on the internet.
Basically those are identical however, I see different potentiometer values. Namely:

Schematic 1:
Gain - 1M
Master - 1M
Treble - 250K
Presence - 25K
Mid - 25K
Bass - 1M

Schematic 2:
Gain - 250K
Master - 150K
Treble - 250K
Presence Orange - 25K
Presence Red - 100K
Mid - 25K
Bass - 1M

Which values correspond to reality or is this the difference between the versions that were released at the time?
