Boss "Always On"

[woulfer]

I have a friend with a Boss NF-1 Noise Suppressor that he wants modded to be always on. He keeps in the back of his rig, and doesn't want to have to turn it on each time. I thought this was as easy as removing one of the fets in the flip flop, but thought I'd check here first before yanking components. I did search, but came up empty handed.

Any insight would be appreciated.

Hate to say it but buy a Rack mount Decimator.  Easily the best out there.  The difference is day and night.

Getting around the bypass would be some surgery that would be hard to explain.

what happens when you have the footswitch pressed down all the time, does it start up with the noise gate on?  could be as simple as pulling the little switch out and shorting the contacts together, or even taping it down or something.

Otherwise you'd need to look at the FET switching, which may be implemented in a unique way in that pedal.

Theres this article, might help:

I can tell you that shorting the switch won't work.  It's a momentary switch to begin with so the switching system inside could get all messed up trying to figure out what you want.

You have to reverse engineer it and then remove the two ICs that do the switching and put in a couple jumpers.

Find a Boss schematic that shows the switching system and work from that.  They're all the same pretty much.

I do have the schematic.



It looks like Q7 and Q8 are the flip flop. That's where I was going to start. It's what to jumper that has me confused. Any ideas?

can you forward me the scheme?

The nice thing about Boss switching, is since the signal never goes through the switch, you can move that switch as far out as you want.  I've added extra leads to the momentary switch, and run them way out to the front of the stage or wherever. 

You could put a small momentary push button on the front of the amp, or on the channel footswitch of the amp or whatever.  Not quite what you're asking for, I know, but you can leave the original switch connected, so if you ever want to use the pedal with a different setup where you do want to turn it off and on, you don't need an external box to do so.
