SHO Clone weird noise

[williamsij]

I recently built a SHO clone, and it works great thru my Fender Hot Rod Deville 410. I love the sound. However, when I play it thru my Vox AC15CC, there is this weird high frequency sound that appears. As soon as I turn it on, no matter how high the booster is set, it makes this noise. When playing, it kind of gets drowned out. But it's definately still there.  Same exact setup for both amps. Same power supply. Same guitar. Same cables.... same everything except for the amp!

Has anyone else had a problem like this?

Yeah, that's the nature of the SHO. Try the Mosfet boost for much quieter clean boost.

I messed around with my setup last night and discovered that it was making that noise because of the way it was powered.  I had it daisy chained with my DD-20. As soon as I separated them, it was 100% better. That's weird that the Vox picked up the sound when the Fender didn't.
