g1  that is the one.

Conflicting info on this one.
On the left is a rate & depth control for Tremolo.
Assuming the 400-210 is the same as the schematic posted, then Pin #1 of the ft sw socket will turn on & off both the Distortion & Fuzz circuits.
No either or. Simply both.

[g1]

Jazz, I think the schematic you posted is correct.  It has blend pot and master pot.
And the footswitch you posted has button labelled 'effects' which would be both fuzz and distortion.

Plen, the 4 button fs you bought, what model amp is it for?

[plen]

g1 it is this one. i put an extra switch in it and wired it the same as the layout post. a few of the switches seem to turn things off and on. i dont know if is wired right for the amp.

[plen]

i just seen this for sale add for the same amp. it has a foot switch. it is the foot switch Jazz P Bass posted. it is different from the schematics posted. on the schematics it is selector combiner distortion reverb tremolo. on the foot switch it is selector combiner reverb tremolo effects.

is the photo of the din socket the back where you solder to.

[g1]

No.  Looking at pins from front.

If you look real close there should be numbers on the rear of the plug.
