I usually use 2k2 resistors for the LED, but if that's too bright, try 4k7. The diode is for polarity protection between the power source and the circuit, so you'll want a diode with as little voltage drop as possible. The 1N4001 will certainly work, but better to use a 1N5817 or 1N5819.
Hi I just put this together and work like I figured It would aside from the echos being much louder than the dry. Is there an easy way to add a mix or resistor change to reduce the repeats volume ? Thanks for all the layout by the way. Great work here.
BUT - Oliver Ackermann currently has this pedal on his A Place To Bury Strangers pedalboard and has mentioned in interviews that he designed it to have the drive and repeats intentionally blow everything else out.
That having been said: the following idea is basically the mix pot from the Catalinbread Montavilian and, if implemented here, it will most keep the overdrive in play. From pin 2 of the TL072, run a 12k resistor to the anode of a 1uF electrolytic cap. Connect the cathode of that 1uF cap to leg 2 of a B100k potentiometer (this will be the mix pot). Connect leg three of the mix pot to leg 3 of the Feedback pot, and leg 1 of the mix pot to ground. You may need to raise the value of the 12k resistor since the signal coming off pin 2 of the op amp has so much gain. This idea is untested - and also, bear in mind, I only SORT of know what I am doing here...
Looks great! Do you have a schematic for this, or go straight to DIYLC?
ReplyDeleteThere was no schematic for this. Just the card as is.👍
ReplyDeleteThere is a hand drawn schematic on my desk actually...;-)
ReplyDeleteTHis one is now verified, once again by Henrik.
Cool! Any chance you could share a photo of the schematic?

ReplyDeletewhat size resistor should i use for led and would 1n4001 be correct for diode ? thanks

DeleteAwesome !!! cheers man for your help .
Deleteso sorry to be a pain but 1 more question....the 1.2nf cap can i get away with a 1nf instead ?
DeleteSure, no probs

ReplyDeleteShort answer: yes, you should be able to do that.

Thanks, very easy to try. I didn't know about the pedals intention. I can get some really gnarly rhythm riffs with the loud repeats as is.
