Thanks, Cody, that answered at least two of my questions right away!

Thanks, Brian. There's a link on the commonsound website that says, "forum," but doesn't work.

Anyway, my question(s) is about the Phaseur. I'm building the pedal with the pcb and and bom, but there're no notes, so  appreciate any support y'all have:

1) will the \"9203\" type LDR, in the link below, work in the project?

2) Do I bend and face the LDRs toward to the rectangular LED?

3) Do I have to make a cover for the LED/LDR combo, like in a unvibe or is pairing open in the enclosure?

Thanks so much!

Hi All,

I'm having a difficulty accessing the 4ms forum, currently; it might be down. Can I ask a 4ms question on this forum or can someone recommend a more appropriate place to do so?

Thanks!

Hi All,

I'm getting some pretty serious popping in this feedback looper (diagram below). Does anyone have any ideas of how to mitigate it? Would a pull down resistor/circuit work? If so, what components, values, and placement do I need to install one properly.

Also, I'm curious if it would work to wire a Bacon Bits into this circuit. This is how I was thinking of doing it:

1) use a toggle 3PDT switch
2) wire the "input" of the Bacon Bits to the "input" of the feedback/loop circuit
3) wire the "output" of the Bacon Bits to the "send" of the feedback/loop circuit

Additionally, I have not wired the Bacon Bits into the feedback/loop circuit, yet. The popping is happening with the just the feedback/loop circuit.

Thanks for any help!

Hi All, I'd like to build a feedback looper as described in this link: http://media.tumblr.com/tumblr_lfwjj510Ya1qemwmy.gif.

I'd also like to add a bacon bits boost to the pedal. I figure it would be easy enough to put a toggle switch in series with the power supply with for the boost to turn it on and off. However, I'm not sure how to wire the boost to 3DPT switch so that it is before the looper "send."

Basically, I want to wire a boost PCB into the looper pedal so it's like having a boost in front of whatever is in the loop. I would greatly appreciate it if someone could please give me some ideas for how to do that, thanks!

Mine drops volume on the filter section, and I haven't found a remedy for it yet. It might just be the way it is.

Thanks!

Both sample/hold and filter settings worked first try, but I was attempting to mend a volume drop in my filter setting and replaced R15 with a 100K resister, which I read about someone trying on this forum. It didn't work, and in the process of the swap, I think I blew out IC4. I'm getting quite different readings between IC4 and IC5 and some "0" and low voltages on IC4 that I don't think are correct.

ok, thanks.

Thanks for your help.

Yes, and I'm not getting any sound out of the sample/hold side.

Hi, the sample/hold feature setting of my sharkfin is not working; the filter is fine. The sample/hold was working, and I think I blew out IC4. Does anyone have the voltage values for that IC? I'm getting what I think are some weird readings, and I want to compare. Thanks.

Hi All,

I love the Sharkfin I just built, but it has a noticeable volume drop on the filter setting. I've checked and rechecked the components and played it directly into my amp--no pedals before or after--and it still drops volume. The sample/hold side is fine and sounds great, finally have it dialed-in pretty well. But I'm hoping someone might have some ideas on the volume drop. I'm also relatively new to pedal-building, so if there's a standard debugging or fix for volume drops, I'm not familiar with them. Any help would be greatly appreciated, thanks!

I just build a Sharkfin and it fired up first try and sounds super cool! But I need assistance with two areas:

1) there's a noticeable volume drop from the bypass signal when the filter is engaged. Does anyone have any ideas about why that might happen and how to fix it? Is it a circuit issue or a rig issue?

2) I followed the build doc instruction for setting up the sample/hold function, but I'm wondering if anyone has any additional suggestions for dialing in a well-articulated sample/hold sweep?

Thanks!

Thanks, Paul, I definitely need to build an audio probe!
