PCB

The Steel Panther 1987 is a new pedal that constists of delay and distortion.

There is not much information about the 1987 pedal yet. I have one, so I decided to look inside.

I was mostly interested about the delay implementation.

Delay

Delay is implemented using CD2399 chip. This is apparently the same as PT2399 chip, which I also have myself (but haven’t used yet).

It contains 44kbits of RAM where the audio input is sampled to.

Resistor on Pin 6 and selects the delay length, which is connected to pedal’s Delay pot. Datasheet states delay times between 31..342ms.

Opamps

Pedal also contains two 4580 general-purpose audio opamps, which are quite similar to NE5532.
