Boss FS-5U ... need some help

[laurie]

Does anyone have one they can test for me? The "mode" switch changes the pedal from "normally open" NO to "normally closed" NC. I can't find info about what the switch position does. Is setting it to the left (looking into the front of the pedal) setting it to NO or NC?

My FS5U is from March, 2000. Made in China.
When the switch is closer to the jack: Normally Closed.
Away from the jack: Normally Open.
This FS5U was bought new 23 years ago, and is used NC exclusively with my DD5.

For reference/cross reference with my March, 2009 FS5L, also made in China.
When the switch is closer to the jack: it's open when the LED is lit.
When the switch is away from the jack: It's closed when the LED is lit. (I use this setting with the SD2: red LED corresponding with Red Mode

This is parallel, if you consider the LED being lit on the FS5L = pressing the footswitch down on the FS5U. I'm postulating that this is the circuit standard for BOSS.

Thank you!!

For future reference.

Based on the experience with my DD-7 and now RC-3, plus bigtone23's experience with the DD-5, it appears that the Boss "standard" for external momentary action switches is normally closed ("NC") for modern digital pedals.

Made this out of:

• 2 x Carling NC momentary switches

• 1 x Rean stereo jack

• 1 x 1590ABK Hammond box

Functional equivalent of an FS-6 set to "unlatched" and "normally closed". Works perfectly connected to my RC-3 with a TRS cable.

Total cost about USD$30. Tiny footprint - much smaller than a pair of FS-5 or an FS-6.
