530 tube preamp with a low volume when pedals in loop

Whenever I plug any pedals in my 530 preamp loop I have a massive volume drop. 80% or so.

I have tried using a single pedal of different types and get the same result.

My cables are 20ft each. I am not sure if that is the issue. I tried putting an input buffer at the end of the send and it didn't help.

I am using Mogami cable so I know it is quality stuff but before I went cutting up cables I wanted to get you guys freedback.

I have also tried switching the return from left to right.

Thanks,
Donnie
