Did you ground the jacks of the fx loop? That was my problem at first... its not clear on the layout but they have to be grounded

He did ground them in the photo above.

My guess is they may need some chopsticking. They can be susceptible to noise depending on position. If it's a long run to the board, the wires should be shielded.

Any value changes I could try to tame the high end just a bit. Treble is always off and still really bright. Thanks

What speaker are you using?

I thought my amps were too bright too when I played them at home. Without changing anything I find myself putting treble on 8 to 10 in a band situation... just saying...

Greenbacks in 2x12 and WGS et65’s in 2x12 and vintage 30 and et65 in 2x12. I haven’t jammed it yet in a band setting but alone the treble is off or on 1. This amp definitely needs cranked even with master volume to get anywhere close to an 18 watt overdrive. I wonder if a dr z air brake would help?

Try running just 1 or 2 greenbacks and see how that sounds. Avoid the Vintage 30s and its clones, as those are inherently too bright for these amps.

An attenuator will definitely help. I made docs for an air brake clone, called the "Break Wind." You can make your own with the doc here: files/JMPGuitars_Break_Wind_Attenuator.pdf ...or buy the one I have for sale on Reverb.

Thanks,
