O pot é o controle de velocidade do LFO, 1M. Porém nem no esquema eles informam qual a curva do pot.

E tem dicas sobre o EH1048.

Potenciômetros CTS são marcados com 137 + ano + semana (de 01 a 52).

Ou seja, o pedal tem 33 anos.

Talvez haja um mau contato nos terminais, que esteja levando-o a obter uma medida incorreta. Tente medir diretamente nas extremidades da trilha de carbono.

Maybe the pot has a bad contact among the carbon track and the compressed terminals, causing a wrong measurement. Try to measure right at the ends of the carbon track, not at the terminals.

Pode estar com a trilha danificada, também.

Its track may be damaged, too.
