Help identifying a capacitor

[Gypsey Eyes]

Hi,

Does anyone know what the value of this cap might be? It's a small disc with 50 on it, no decimal or anything else. It's from an old MXR Preamp pedal.

50pF would be my first guess.

Looks to me also. And a glance at the schematic for whatever MXR model this is would verify that.

thanks guys. I couldnt find a schematic as this is one of the more obscure MXR pedals, the predecessor to the microamp I think. I got a 47pF cap - the closest I could find - will try it on the weekend.
