Hello to all!

I have a Fender twin reverb, and as you know has two channels, the normal channel (tone control only) and the vibrato channel also has reverb.

What I want to do is to the next modification:

Use the normal channel with reverb also, but not vibrato.
This means that each channel is independent but the reverb affects both channels, and vibrato only his channel.

Anyone have idea how to make this modification?
Has anyone any modification scheme?

Thank you all.

Frank.
