These seem really impressive. I'm surprised it's not verified. Can the usual LED lug on the stomp switch be left bare, or is it best to have the usual indicator LED, and the rate one too??
I've been thinking about this....and maybe it's best to connects two wires from 'rate Led -' and take one to the led -, and one to the stomp switch led lug. (This would mean the led starts to flash when the effect is engaged? - someone put me out my misery before my tiny little mind pops 🤣🤯🤷🏼♂️)
Haha Anders should beat people in. The led on the board will show the rate regardless of whether the effect is on or off. So you would need a separate indicator.
Wait - Sorry! Does this mean I take the wire labelled 'LED -' on the board to the stomp switch....and then from the stomp switch to the physical LED minus leg?
I'm so sure I've built this to plan....I've checked so many times, but sad to report it's not working for me. The LED pulses with the rate, but I get no effect. Silence on the middle switch position and clean bypass on 1 and 3.
I'm taking a crack at this. I had the same problem as Ian, checked the schematic and resistor at I/20 should be 470R, not 470K. Now the modulated signal is audible but very distorted coming off pin 9 of the LM13700. It's clear going in to pins 10 and 12. Voltages are: 15: 5.25 14: 4.58 13: 4.58 11: 8.75
Works really well! But does anyone know how to make it more neutral sounding? It adds a quite lot of treble to the signal to my ears. I would also like to increase the available depth; could it be the 4,7K resistor in the upper left corner?
I built it last year (using another layout obviously), and it is a very recommended build : easy, and great sounding!
ReplyDeleteSecond, I built it last week (other layout) and like it very much, especially the swirl position
Delete3rd! Totally worth building.

I would just add a separate status led. But you could try omitting the led- on the board and instead running that side of the led to your switch.
ReplyDeleteI wonder if if you had both the status LED and the rate LED, the status LED would blink continuously even when in bypass??
ReplyDeleteI checked tagboard effects and that doesn't have the rate LED and obviously I don't want to build that one because I'm dirtbox4life 🤜🤛

ReplyDeleteNice. Thank you 🤜💢🤛
DeleteMaybe a 4pdt stomp switch can work by grounding the LED in bypass?
Delete🤯
DeleteHey Anders...I'm getting the box ready for this...what's the final word on the LED?
ReplyDeleteUpon seeing the size of the board, I'm hoping to just use one...😳🤣
Hey Ian. I would only use the Rate LED. You can connect LED- to the footswitch just as you would connect a normal indicator LED.
DeletePerfect! That's the answer I was hoping for! Cheers!
ReplyDeleteWait - Sorry! Does this mean I take the wire labelled 'LED -' on the board to the stomp switch....and then from the stomp switch to the physical LED minus leg?
ReplyDeleteSorry to be tedious
Yes, ditch the board connection LED-, LED- should be connected to the switch only.
DeleteBecause pin 4 on IC3 is ground!🤓

I'm perplexed!
Good to know it wasn't just me struggling.
ReplyDeleteI also tried the tagboardeffects version with no joy
Found it! Had a super tiny pad lift. So many hours lost! But it works great now.
ReplyDeleteWell done! In was left questioning the if all my chips error genuine...
DeleteExcellent!
