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!
Dream '65 hum at <25% volume

It is like that!
Same with mine, even got a replacement after sending it in. Same problem. It goes away the higher you turn up the volume.
I tried many different power supplies and cablings. Even with a Boss 9v supply directly into the interface, the low frequency hum is there. It’s around 60 Hz. It’s as present with single coils as it is with humbuckers, doesn’t matter.
Maybe someone from UA can shed some light?
tell us more about this boss 9v adapter ? Which one is it ? Have you tried it with other 9v 500ma + adapters ?

The Cioks “Sol“ is a ‘switch mode’ power supply.
Any switch mode pwr sply can potentially induce noise with some devices, especially those devices that require a big power draw that needs to be consistent regardless of how many mA they deliver.
Try the Dream65 with a Boss PSA 120 S (linear power).

UA do say this on the UAFX site though.
Any modern high-current pedal board power supply that meets the requirements below will work with UAFX pedals. Manufacturers such as Voodoo Lab, Cioks, Truetone, and Strymon make power supplies that work great with UAFX pedals.
Not in my case. It might be the preamp in my hifi. It is worth noting that I also have a Woodrow that is super quiet in the same set up.

Yes, they mention Cioks but not the 'Sol' specifically which, reading the literature carefully, indicates that its "switching" type is different than Cioks other offerings. I'm not saying that it definitely is the issue, I'm just saying that it's possible.
I’m trying to figure out why there’s a 60 Hz hum using a battery, are the instrument cables running near / parallel to any power cables? Or near any LED or fluorescent light fixtures? Cables in good working order? No grounding issues on the amp itself?
I just ordered the Boss supply you suggest. I will report back!
It might be. The friend I recommended the Dream to has an original and was A/Bing them blind. He called the dream as the original because he heard the hum! It sounds great, I am not crapping on it. I just want to figure out if I can stop the hum.
I have a Truetone too on another board, I will pull it off and check tomorrow.
