I don’t know why they did it, it’s just a regular LM308 in a 14 pin package, with lots of unconnected pins, and two that are labelled “Guard”. I think they’re “rare” as they were only made for a short time, and the pins are gold plated also.

I was keeping an eye on that! Glad you snagged it and got some sound out of it. Post some sound clips if you get chance.

Very interesting. What a pity it's not a double, only gold version. :hihi:

Still messing around with it this week - there are two points that look like they should be were the distortion pot on a Rat would be, but I tried that and it weakened the distorted signal to almost nothing. Yesterday I tried a 2M2 pot there and it works! the value on the Rat is only 100K :hmm:
Clip on Sunday maybe

Whatever value sounds cool. Looking forward to hearing it, especially if it has a rat taste to it.
