I am getting a hum with the Freeze in my pedal board. The path of my board is Bass->EHX-2020Tuner->EHXBass Preacher->EHXBassSoulFood-> EHXNanoBassBigMuffPi->EHXFreeze->Tech21 Sansamp Bass Driver DI V2->amp. Pedals are powered by EHX S8 Multi-Output Power Supply. Sansamp is powered with a Trutone power supply. I went through an elimination process of checking each pedal separately (bass->pedal->amp). The Freeze was the only pedal that hummed. I tried using a separate power supply with the Freeze; hum was still there. I removed the Sansamp from the board. It did not make any difference. Any idea what is causing the hum? I don’t remember any hum when I first got the pedal.
