I fried a LED!!! + some mosfet boost question (no unity gain?)

[pott]

My first one 


I was using the LED out on the mosfet boost PCB but it didn't take it so kindly... I have an extra hour to finish this (everything works fine).


So what size resistor should I use in series with R4 in order not to fry the next LED? I was thinking 10K?


Also, there is no unity gain. The pedal when on is always a little louder, even with the gain all the way down. The taper is also wrong using either A or B pots... no idea why not. But apart from that it works fine.

The mosfet boost has a minimum of +3db gain, I believe. You can try a reverse audio 5k pot, if you want something different. Smallbear has them.

1k-4k7 for LED's is fine. I usually use 1k.

Thanks. Problem now is, what's this 'led' output on the PCB? I have no idea what to do with this.

Which layout are you using?

[pott]

None. Well I kinda used GGG's for help but figured out most of it.

There is no LED out on the ggg PCB.

If you can't figure out what the LED out is for, just ignore it and connect the LED to 9volts using the resistor like shown here http://www.generalguitargadgets.com/diagrams/ge_boost_lo_amz_mosfet.gif

I was just using the layout as a guide for the rest of the bypass. I just did as you suggested and everything works great, awesome! Thanks!
