How do I mod 'Normal' channel into outboard style reverb controls?

[KissTone]

I saw a post on a "surf" music board about modding the 'normal' channel of a reverb-equipped Fender amp so that the normal channel controls function much like the mix, tone, dwell controls on a Fender outboard reverb.

Supposedly, this mod was explained in one of Weber's columns in Vintage Guitar magazine. Has anyone ever seen/done this mod?

I figure it's a wee bit more complicated than running the pan's output into the normal's input. :)

Also, does anyone know if the reverb tank in a DR is the same as the tank in the outboard unit?

The reverb control on the amp is the 'mix' control. If you replace the 1M grid reference resistor on the reverb driver tube with a 1M pot (wiper to grid), that would be the 'dwell'. For tone, you'd add a cap (.1uF?) at the plate of the reverb recovery tube, a 50K pot with a cap between its bottom terminal and ground, and connect the existing .003uF cap to its wiper.

If you think about it, what the amps have is a setup where dwell and tone are full-up.

where he dumps the reverb return into the front end of the normal channel.. that way you have dwell and tone controls on the reverb

No, it's not the tone del maximo---that's what GW calls a multi-amp setup free of ground loop problems.

Anyway, guess what I found on google books? Yup . . .

I had no idea google books let you preview a cool book like Weber's . . . and the preview just happens to include the instructions on converting your normal channel to reverb controls. Looks like the Admiral's got the right idea.

his other thing was to swing the reverb return into the input of the normal channel to get tone controls also
