Helo everyone, i am planning to build the Pultec EQ1A based on recproaudio project, point to point, as much as close to the real thing.
According to BOM the two log pots 10K and 100K (LF Boost and Atten) are rated 2W. Is it critical to go with those specs or i could use common 16mm log pots rated at 0.1W?

The actual power is under 0.002 Watts.

The 2W part is industrial grade and can be used 20/6 for years without interrupting your session.

The teeny-Watt pot has been good enough for all your amplifiers and pedals. You are not a million dollar film-sound studio.
