Re: BAJA Korg CX3 Rotary Effect [documentation]

Does anything like this exist on the market? I'm looking for this exact effect - it looks like it's pretty much a BBD chorus pedal that spilts the highs and lows and gives a similar effect to a Leslie speaker... And I want it this way because I want to plug it into a guitar or bass amplifier, as op...

Re: Himmelstrutz - Fitzo

I got the pedal opened up, removed the black goop, then had to remove white paint, then discovered that all caps and transistors values are sanded off. I'm guessing the last thing to do is measure each component with a meter? How do I go about doing that to find the value of each cap and transistor...

Re: SoulSonicFX - Stage Overdrive - The Klon Killer!

Looks good! I think I'll try this with an NE5532, with the second opamp used as a summing amp at the output, to mix clean and overdriven sounds. Hi, You can try also : IC1--TL071, IC2---MC33172N , IC3----ICL7660SCPA(max 12V). Power consumption:~5.5mA. IC1 ---NE5534 (more noisy and current rise to ~...

Re: Dumbloid [traced]

well, i'm really happy with the MC33172N and I tried a couple of 4458's (RC4458P, JRC4558D) and they had fizzy decays too. a JRC4562D sounded a bit better than the OPA2134 to me but still was a bit fizzy. the TLC2262 is one that I didn't happen to try since the MC33172 sounded so good, but I might ...

Re: ancient prophet boost/od/dist/fuzz

Sound good Jimmi. I agree with box, if that really is a 1N400x then it will conduct all the time and rapidly flatten your battery. Passing a current limited by the 100R resistor and the internal resistance of the battery in series. A 10v (or higher) zener would be correct but serve little purpose o...
