Is the numbering order of IC2 on the schematic written for convenience? (1,5,6,2,7,8,3,4) It's not the order of the pins on the IC, correct?

I was having trouble trying to get the proper continuity from pin 1 to pin 8, that I gave up and built another Road Rage. I'm thinking that I might have ruined the IC. Once I finished the new Road Rage it worked fine. Continuity and voltage checked out. I'm still getting the hum, but it's not high pitched. It's more tuned to open D on guitar. Sounds similar to a guitar cord plugged into the amp and grounding the tip and sleeve. I believe it has something to do with the Rangemaster.  I will go over the circuit tomorrow and see if I find anything.

Thank you.

Sorry about that error. I measured straight across and no in a u-shaped manner. So the correct numbers for 5 through 8 are:
pin 5 - -9.00
pin 6 - +4.10
pin 7 - +5.64
pin 8 - +9.00
I checked continuity, and I'm getting continuity between pins 1-5, 2-5, 3-5 and 4-5. I went back to check continuity again, just to make sure I have the right pin order. But now I'm not getting anything. When I check pins 1-5 for example I get short beep, then no sound at all.

The pedal is the old Rangemaster circuit. I've upload pictures.

I believe that I have it working now. I'm able to get the correct -9v. But I'm getting a slight hum in bypass mode and extremely loud hum when the board is engaged. I understand that I will be getting some hum from the pedal not being in a box, but maybe it's because I have Q1 connected to breadboard to try different transistors. I found something unusual when was checking for continuity of the potentiometer. Normally what I do is check continuity from the board to each lug of the pot. Then I place a probe on the wiper from the board and the other probe on lug 1 for example, then I move the pot and listen to the tone from the meter. When I do this I'll hear the tone when the pot is turned all the way up and loss audio when I turn it down. Now I hear the tone with the pot fully on and when I lower the pot the tone is distorted.

These are the Voltages

Pin 1   +4.05
Pin 2   +4.64
Pin 3   0.00
Pin 4   -4.32
Pin 5   +8.97
Pin 6   +5.51
Pin 7   +4.06
Pin 8   -8.96


Thanks

Is there a method of search just my posts?

Thank you.

Ok, I've now added the charge pump (7660scpa, jumpered BST) but when I check with a meter, I can see the +9v coming in from the DC jack but when I measure at the -9 G points I get a reading of 0.01 Volts. I then tried measuring at the IC 3 ground and 5 -9 Volt and I get the same reading.

Please help.

Thanks

I populated the board for -9volt D1, D2, C1,C2,C6,C7,R1. And have omitted the rest. Do I need to add the charge Pump?

So, I need to omit D6, D7 and D9. Is D8 part of the signal path?

On the board there are D8 and D9, in the instructions build D8 is Red 3mm LED. I'm assuming that D9 is also a Red 3mm LED.
Is this correct?

Thanks

Nevermind, I figured out that the sw is for the clip switch.

Which number pin for 3pdt footswitch gets connected to the board where it is labelled sw?

Thanks.

Thanks

I built the Deadringer 2 without the battery snap. Do I need to jumper the holes?
