Hey.

It is almost exactly the same. Maybe a different model? But Guyatone, no doubt. Thanks!

I asked a local guy and he gave me an interesting answer. "Since the Dynacomp and Ross compressor have been copied dozens and dozens of times since the mid 70's it is fairly impossible to find out exactly what compressor it is, given the CA3080 and the position of the trimpot it definitely has it's origins in the Dynacomp, but not exactly, because it has 3 pots. 100K A is volume, 500K C is comp, and the last one A504 must be attack or tone. Otherwise it would leave too many options to choose from, but given that this circuit has been "floating" inside the enclosure it narrows it down a bit, because massively produced brands like Aria and such had the switches/jack soldered on the pcb to reduce the workload". So in his opinion the circuit looks like a Locobox, but their catalog does not have a 3 knob compressor, so it leaves us with Guyatone PS-003 (if the third knob acts as a tone) http://www.effectsdatabase.com/model/guyatone/ps00x/ps003 or Frontline 178828 (if the third knob is attack) http://www.effectsdatabase.com/model/frontline/series3/178828.

I agree, it really looks like an old Ibanez pcb. I tried to look for this pedal and i saw that a lot of cp9's are made with lm13600.

Maybe in the really old ones they used CA3080 design? I have no idea.. thanks everyone!

Thanks for your answer! My question is not exactly fair, just wanted to see if someone would recognize some particular element of the comp.

I just got it today on the side of a deal. It is old and in bad shape. i am going to restore it, just don't know what compressor it is.

It has 3 potentiometers, 100K A, 500K C and A504.

Hey.

Ok, problem solved, it was just the horrible power supply.

Sorry for wasting your time.

and thanks!

Hi Jon!

I don't have the schematics, only vero layouts.

Hello.
I made a overdrive multi-box including: red llama->rat->super hard on. When i turn the sho on, i get a terrible noise (most likely from a cheap power supply) does anyone have a go-to filter layout ?

Thank you very much! Now i know for the future how to get help more efficiently. The tremolo started to work when i simply jumped input and output. Maybe it's not the way it is supposed to, but sounds good! Thanks again mgwhit!

Hello.
I built an Kay tremolo clone, and now on testing i can hear the actual tremolo chopping away, but no guitar signal. if i strum hard, the i can hear the guitar for a second. what could be wrong in my build?

What do you guys think. is it even worth trying?
I have 2N2222 germanium and silicone versions.
do you think it can be possible to use one of each in a fuzz face clone?

Ok! That seems interesting! Have to try that.

Any idea how to include also a led to dpdt switching? I know it would be easy just ti use a 3pdt - switches which i have plenty, but the effect i'm building is so ridicolously small, that any stompswitches won't fit.

Oh yes! I have also thought about relay controls and been fascinated by it, however for the time being i need to go and get dpdt or 3pdt switch,  because i need to mail my effect out very soon.

Thanks kothoma, i thought that it probably wouldn't work.
