Yeah... if those old pedals with electrolytic caps haven't been used in a long time, those e-caps will dry out just like an amps filter e-caps if it doesn't get any use.
I have one of those Blue ESR meters, too. This is a very useful diagnostic tool to have...

Do you plan to use it for anything else but effects pedals?

I've been looking at that on Ebait for a while now too but the curve tracer is a bit too dear for me too! been trying to find the lowest priced one but no days on that. If I find one I'll give ya a heads up so we don't bid against each other ,just in case! All the good stuff is priced too high but it's worth it if it serves it's purpose well and the pockets are deep

Looks like the Peak tester is a joke for real world testing 12 volts applied voltage max
for what I want it needs to apply 100 volts. Oh well live and learn turn and burn

Damn... Those real curve tracers really are expensive: $10,000... WTF?
I liked them both(the chips).
Do they sound different?...yes. A bit. Seemed to be more upper mid and high on the last bit.
Well done demo sir!

The vintage Motorola LM308 is installed in the 8-dip socket. The modern LM308N is hanging on the upper edge of the pedal:
I hear the same difference too. And of course, I like them both also!

Well done Sysco, & nice playing. I'll need to give this a proper listen later. I did listen to it on my phone (without earbuds) while in the rattley old work truck & "think" I could hear a slight difference, though I'll need a better listen to be sure. I do know that on DIY FX forums the Motorola TO-99 (metal can) LM308 is considered an up-grade, though I've never done a comparison. ApparentIy the TO-99 chips were only used in the early prototype Proco Rats. I grabbed the NOS chips because two of them were only about 2 Aussie bucks dearer than an over the counter purchase of current production (Chinese) LM308's. Cheers

Thanks!
Silly me... I forgot to mention... I used the old lady, after not touching her for a long time...
Yeah, I used my old '71 SG Standard, that has a set of Fralin PAF humbuckers for the demo. This guitar has always had a very embedded wooly-ness to its tone. What ya hear on the clean signal in the demo is pretty indicative of that wooly-ness that I'm trying to describe.
Nope.Seriously, am I the only one here who doesn't have a vintage SG?!??
