SOLVED Noise with the Sea Horse

Hello everyone, I rencently bought the sea horse kit.

When I engage the pedal I hear a sound like a "Pock" which it's not normal.

This is the sound in question.

But also I hear some noises in the background while the pedal is on.

It's very annoying ...

I have searched a solution for this problem, I have test the ship's gates of the TL074 and the LM324N and they are good.
I have put the PT2399 on an another pedal (Pitch Witch, great one !) and there are no problem so the PT2399 works too.

How to fix the LFO tick in the Sea Horse and Dark Rift

I've found a simple circuit mod that gets rid of the LFO tick in the EQD Sea Machine (Sea Horse) and Space Spiral (Dark Rift). It has been tested on both pedals. It's the same mod for both pedals, only the ref designators are different. Sea Machine: Remove C19. Connect a 10nF cap between pins...

I saw this post, is it the same problem with my pedal ?

If you want I can send some pictures of the pedal.

I hope that someone can help me !

Thank you very much for reading this.

Can you read which revision of the PCB you have? It should be written on it. If you bought it as a lot it’s possible you got one of the old boards without the fix for that built in. Follow Chicks advice on that thread if that’s the case.

Thank you very much for answering !

It resolves the thick's problem, I don't hear the noises anymore in the background.
The "pock" when the pedal is engaged is still hearing but it's very low compared to before the mod.

I have the PCB025 and there is no "REV 1.3" written.

I saw that there is also this problem with the PCB.

Sea Horse wrong schematic?

I think the schematic had a little problem, the pin 3 of INT pot should not be connected directly to the LED(D1), instead, it should be connected to the point between R31 and IC4.2's Output(Pin 7), so the Vf of LED won't effect the oscillator, and you will get a really tiny effect if you don't...

There are the componants soldered into the PCB so I can't see if there is the "wrong" connection.

Do you think my PCB has the "wrong" schematic ?

Is it just your switch popping now when you turn it on?

 

[thecakeisaspy33]

Yes it's that. When I push the footswitch and when the power is on.

I think all the problems are solved.
Thank you very much for answering and helping me !
