Build Your Own Clone Message Board

Just wondering if the upgrade "mojo" kit really makes a big difference. Anyone built it both ways and compared them and can describe the differences? Thanks.

Well as you know BYOC claim -

With the Vintage Upgrade
Pack, the compressor has all the squish of
the CA3080E/2N5088 combo, but with a
more natural attack, more overall volume,
and better retention of high frequencies.

I have to say I am a little sceptical. What might make the most difference would be the 3080 OTA IC as the fab process and possibly even the internal circuitry may be different. I can't see anyone being able to hear the difference between one type of general purpose silicon NPN transistor and another similar type in this pedal. I think this has more to do with how obsessive you are about building as accurate a clone as possible.

But what do I know, I have to admit I have not built and used this pedal with either set of components. It would be an interesting experiment for anyone doing so, and / or adding the 'upgrade' to first try it with just the 3080 changed and still using the 2N5088s (or 2N3904).

I don’t claim to have the most critical ears but when I swap op-amps I don’t hear any difference between them. If not also swapping out the 2SC1849 transistors for the 2N5088s is the reason for this I don’t know. I didn’t socket the transistors.
