peppermill vero - offboard wiring

[jeff g]

I'm building the ROG Peppermill on vero using Torchy's layout, but I can't figure out the offboard wiring. 

I was going to use the 'offboard wiring 5' diagram from Tonepad, but I don't know how the LED is hooked up.  Whenever I've used a 3PDT and LED in other builds, the LED goes to switch and DC jack, but on Torchy's layout there are LED + and LED - connections from the board?

Also, where does output go?  In searching the archives, I found one post where it mentions that Vol lug 2 is the output - so, Vol lug 2 goes to switch (top right)?

thanks

well, I'm still trying to work this out.

I've searched the archives, compared other vero layouts (e.g. Dragonfly), compared with other builds I've completed and tried to sketch out the layout, but I still can't figure this out.

It's the LED off board connections that are confusing me.  Maybe they're called something else in other layouts?

Can anybody help me out on this?

Thanks

Assuming you mean this layout http://aronnelson.com/gallery/album28/ROG_Peppermill then yes the output is from volume 2.
A lot of layouts don't include the LED at all so you have to figure out where to connect the LED and current limiting resistor yourself. On this layout Torchy has put the current limitng resistor on the board, its the 3k9 resistor. So you just wire the Led+ to the anode of the LED then the cathode of the LED to the switch and the return from the switch goes to LED-, which is ground.
Hope that helps

Thanks Slacker, it's starting to make sense to me now, but...

I assume LED+ from the board goes through DC Jack first, then to LED anode, and then to top centre of switch (without a resistor between cathode and switch)?

Then, does the return from the switch come from the same switch lug?

Also where does the 9V+ from the board connect? - I thought these usually go through the DC jack, but the LED + is going there?

Sorry for all the questions, but these off board connections are different than I've used before and when I try to plot it out, there don't seem to be enough lugs to accommodate everything.

Second row down on the left is the 9v+. Thats where your battery or power
jack would connect. The LED + wire is only for the LED +

[jeff g]

I'm confused again.

Wouldn't the middle row / left lug on the switch be the board IN connection?

I thought that 9V+ from board connects to DC jack / top lug, then through the indicator LED to switch?

Maybe it's the text explanations that aren't making sense, is there a layout wiring diagram anywhere that shows this particular wiring?

[Torchy]

Its not that hard if you think about it logically.

[fixr1984]

I'm an idiot. I meant on the right.

Thanks Torchy

I know it may seem obvious to some, but it's a bit of a learning process for me and I find it hard to understand why there are so many different methods of offboard wiring !

Anyway, I wired it up using your diagram, but it's not working (no sound bypass or engaged).

I'll troubleshoot now, but in the meantime I wanted to check if I wired the IN/OUT jacks correctly - as is, there is only one connection per jack - correct?

Two...the ring terminal needs a ground connection.

This is tacked to my wall just above the bench because I'm always forgetting the basics of stompbox wiring:

Thanks Dano and everyone else in this thread - it's much appreciated

I have a layout wiring diagram above my bench too, but it's not the same.  I guess that's my difficulty right now, I can't figure out what the basics are - layouts look different to me.

Anyway, I've got it working, using a combination of the wiring layouts posted in this thread (i.e. LED wired per Torchy layout, grounding per Dano / tonepad layout).

As for sound, I'm not sure it's working as it's supposed to.  I get a nice clean boost, but when gain is up high, I get a farty / buzzy / torn speaker kind of sound - but the farty sound doesn't sustain very long and it's more pronounced on low strings. 

Anybody else have this?

Well it sounds like you have the offboard wiring correct now (if you are getting a clean boost). Have you adjusted the trimmer to about half of the supply voltage? In other words if you are using a 9v battery, the trimmer should be adjusted to about 4.5 v if memory serves me....

Keep at it, it can be frustrating, but you'll learn all the pitfalls pretty quickly
