This is the discussion thread to my extensive KORG PME-40X report. If you have anything to contribute, please share it here.

Nice writeup pepe!

Very interesting read, Pepe. Looking forward to the rest of it!

Thank you! Since I don't have original pictures of many of the effects mentioned in the chronology of Japanese multi-effects, it looks a bit sterile, though.

So if anyone can supply own pictures, I would be very grateful!

Things can be edited and added anytime.

Very nice, thank you for posting all the cool info!

I still have a UE305. I used to have two, bought them years apart from each other in the 90s. One was very clean and the other pretty played and a little rough. When I went to sell the rough one, I noticed that they had consecutive serial numbers! Wanted to keep it just because of that, but having $$ for other pedals won.

Consecutive serial numbers are fun, indeed! I think I have two KORG PME modules with consecutive numbers ...

very cool! I'm reading through all of this, excited to hear more about the PME40x units. it has occurred to me the pme40x system is affordable I might have to get into it!

It is still affordable. It is one of those vintage systems that is flying under the radar for many years now.

I am working on the documentation in the background, always trying to collect as much information as possible. Yesterday I bought one of the last two remaining manuals that I haven't had as a physical copy yet, the KPH-401 Phaser manual, which will arrive with the post in the next days.

Should someone own an original KDW-301 Dist Wah manual, I'm willing to buy it off for 20 EUR plus shipping!

I don't have any decent pictures of the original box of the PME-40X pedalboard, and neither of that of a Yamaha PSE-40A or any manuals or packages of the Yamaha-branded effect modules. I would be grateful for any photo that I am allowed to use. Thank you very much in advance!

I'm 100% positive that the Korg units are really killer, because... Korg.
I'm 100% positive that I don't need another rabbit hole of pedals to go down...
