Hello, I will begin by introducing myself first. I have been a member, (formerly hank75), for many years but am not able to log in anymore as my email is not valid anymore. I haven't been active in music for a few years, but returned to it about 9 months ago.
Anyways, I just got the Analog Chorus kit for Christmas from my girlfriend. I did build this very kit years ago and loved it.
I'd like to have the indicator LED just turn on and off.
Looking at the schematic, I think it should just be a simple extras steps, but I could be wrong so I thought I would ask.
If I do not install Resistor R29 and Q4 But put a 9 Volt jumper to the pad of Q4 that goes to the anode of the LED. it still will have R28 functioning as the current limiting resistor for the LED. Will this work?
Where to Hijack 9V from?

Yes....but even more simple than that. Just omit Q4 completely. Nothing else. Then place a jumper between the emitter and collector pads (the two outermost pads). The 1k limiting resistor might be a little too bright, especially if using a clear LED. If so, just replace it with a 3k3 or 4k7.

Thank you :D
I thought of that, but wasn't sure what that "+V" voltage would be at Q4
