I recently encounter some problem on the tone control on my Squier 50 Classic Vibe Telecaster Bass. When I turn the tone on full i can hear some cracking noise, like some static. When i play some notes and some harmonic i can hear static noise. But I when turn the tone down completely the noise is gone etc. I usually play with tone down but i do want the tone on sometimes. The tone is very very bright when turn on full so it maybe a 500k pot instead of 250k standard.
