Am I doing something wrong, or is there a very noticeable hum on this at low volume settings? I am using a Cioks Sol to power it, although I have tried others, switching supplies, transformers etc. No other pedals in the signal chain, just an OBNE Split Meld to take the outputs to TRS. Then directly into a Quad 33/303 hifi. The hum is only present on the first 25% of the volume pot. Driving me crazy. I love the sound/feel of the pedal. I tried everything, this would be the best, but I need to stop this hum. Anyone have the same experience and a fix? Thanks!
