microphone echo & delay fx circuit

[bernhix]

Hi,

Can I have a chance to get hold the schematic of the said echo and reverb effect? I will use it in adding echo for my Mics.
My e-add is d_stantman@yahoo.com.ph

I am in middle of making the delay using PT2399, after checking the performance will post the schematic if anybody would like to make it....

Cheers,
Anshuman

What is progress of your project and performance?

i recently found a kit from junk.Perhaps it is a microphone echo circuit.It has two 4558 and one pt2399.I will test it and post the results.

 

[sudhir kumar]

I have tested the PT2399 kit.It is working very good.I have added DELAY,REPEAT pots from the datasheet.I can say definetly that it is worth making when compared to its price and easy circuit.Surely it is not hi-fi but perfectly fit for home use eg.karaoke etc.
One thing more i want to add a DRY-WET pot to it,Please tell me the procedure.
thanks.

I have again tested above referred kit.Result is very very good for voice applications when using the delay and repeat timing very less(most usable).i have added presets for adjusting delay time & repeat.Photos are attached.If any body had made this circuit i want to know about their result.

PT2399 echo/reverb schematic

I want to add a dry/wet pot in this kit.any help please??????????

I have done it 20 days ago, sorry couldn't post the schematic and the kit pic... it sounds awesome, i made it for my electric guitar, you can give it a try and let me know how the performance is, PCB designing and etching is also done by me.... attaching the schematic (2 parts) and the snaps of the completed kit (taken from digi cam).... please let me know if you have any question....

Cheers,

PT2399 is available in bangalore ... i am building another one PT2399 along with compander NE571 which i used for my delay (MN3005)...
If someone else have good reverb/chorus schematic using MN3011 please post the same, i built the DOD FX-45, but not happy with the performance

Hi Sudhir,
I bought it from S P Road one year back, sorry couldn't remember the name of the shop, price was around Rs.100/- (less than MN3011 and MN3005 )
you can email me: anshuman.ivan@gmail.com

Hi anshuman , can you share your pcb design in pdf ???

Hi anshuman , can you share your pcb design in pdf ???

Sudhir, I am not really a professional PCB designer, i only build PCBs to meet my purposes, everything I do manually, draw the layout following the schematic, etching, drilling, etc. You can put much effort for your own design following the schematic. All the best.
