Wanted: gut shots of a Proco Rat

[Feral Feline]

To be honest, I was surprised at how little difference there is between the 308 and the OP07 — Mind, that's just online yoootoob comparisons. I've got both chips, built a Rat but have yet to A/B the chips in person. I'll get around to it eventually...

Most of the A/B videos I've seen on youtube use two different units with the different chips rather than swapping it out of the same circuit. That to me completely invalidates the comparison since so many other variables are being introduced. I have yet to do the side by side comparison myself too. I've been meaning to do it for some time now.

Agreed, but...

Here you go:

Guess we better get on it and compare for ourselves! I don't have "golden ears", but I have friends who do.

 

[mnemonic]

I have a modern chinese rat with an op07 and a parentheses I made with an old metal-can Fairchild UA308. Set the same they pretty much sound the same to me. The 308 gates out easier with high output pickups and high distortion settings.

But I also pretty much just use it for doomy sludge stuff so maybe if I used a strat into a fender amp or something for crunchy tones maybe I would hear a bigger difference.

and sorry chuck I only have pics of my modern rat pcb on the solder side
