hi rnolan,
As i said to MJMP i need to ugrade most of my ada gear so the Eprom have to be replaced anyway, and even it doesn't fix... it will help for sure !
About the store button it doesn't feel different than others... i mean, when you press, it clicks the same way... it's not beat up. Everything is fine until you push this button :
no red led on... and no store mode (you only stay on the last parameter value) edit light and changed parameter keep blinking and nothing else (matters
)
About Editing, everything is fine too : press edit for entering "edit mode", change preset parameters (Tone is changing too)
I replace once again the battery and put on the stongest I had, it's a 2032 type with 2.6volts. I 've inverted polarity to check... no more!
And you're right, i've no possiblility to load factory preset since the store button is unable (well ! that's fine... I prefer my preset !)
What is the deal with RAM chip ? this is something I've ever checked before !
