Fixing a broken Electro Harmonix slide potentiometer

I recently acquired a 1981 Electro Harmonix Graphic Fuzz with two broken sliders.

The Overdrive and the Vol sliders had both been broken off. 

Here's what the broken overdrive pot looked like. 

Luckily smallbear electronics sell drop in replacements! 

The slide pots are:

Overdrive = 100k 

Dynamics = 100k

Sustain = 100k

EQ pot 125–2000 Hz = 100k 

4000 Hz = 10k

Vol = 10k 

So I needed 1 100k and 1 10k potentiometer.

Here's what a brand new CTS 100k linear potentiometer looks like: 

The only 10k CTS slider smallbear sells is reverse log and here's what that looks like:

I installed the 100k linear overdrive pot and it worked great. The 10k revLog for volume worked too, but since it was reverse logarithmic most of the change happened at the bottom of the slider. Not sure if the original is linear or logarithmic. But it was most definitely not reverse log.

Hoping they hadn't changed the insides of these CTS pots. I decided to just replace the lever part. 

You open it by carefully bending these 4 tabs:

The new one:

and the old one:

Here's what the inside of the old one looked like:

Then you move the lever from the new pot to the old one. Luckily it fit perfectly: 

Then you put the top part back on top of that.

And TADA! 

A repaired CTS slide pot! 

And here's what the pedal looks like now:

I replaced the old white slider tops with new ones from tayda for a uniform look.
