This is making me very sad. A previous owner must have used an aggressive solvent to clean this KORG PME-40X.

Wow, that's a strange and rare choice of replacement knobs!

Beautiful! Very clean!

Ah, I didn't see that at first look. How very strange! GDR components in an American amp?!

What good things come from Germany?!

I received another PME-40X pedalboard this week. I opened it today and I immediately noticed the familiar stench of a blown spark killer - yet another one! The shop that I bought it off has a tech who replaced the old spark killer with a small blue MKP capacitor of lower capacitance (0.01µF instead ...

What an awful design! Good luck with the rest of the story!

The other idiosyncrasy is that the DC ground flows through the pedal housing - there is a wire from the boards to the screw that holds down the LED, and the circuit flows back into the boards through the sleeve of the input jack. Weird. And frustrating until you figure it out because nothing works ...

Phew! What an annoying job. But now it finally works again? Which one of the sandwiched boards had the worse capacitors that needed replacement? Only the board with the through-hole components features electrolytic capacitors, am I right? The "unknown" pic is the test of one of the 10uF capacitors. ...

Maybe swapping some capacitors for tantalums could be helpful to approach the vintage sound?

Today we can only speculate how the fuzzes from back in the day might have sounded when they came fresh out of the factory.
