I tried to resurrect my Zoom 9030 yesterday but I have found a very strange behavior:
The compession and distortion effects seem to do nothing except zero the signal...
Time to say goodbye?

My first thought is Why?

but if it has an internal lithium memory battery, replace that.
Then try a factory reset

Thanks for the answer.

Why? It's just a matter of curiosity (can it still be used for some projects today and spare some bucks?**) and affection...(it stayed with me until VG99 in 2011..) I replaced the lithium battery just yesterday and did a factory reset. At a closer look, The Zoom 9030 has a main-board and a daughter-board connected by wires. One of those wires my be damaged..I'm not too much into electronics but I was puzzled by the fact that all works fine except when I put Distortion on .. and the signal goes away. Intriguing isn't it?

** I might have a venue in the future and I was trying to avoid bringing the VG99 with me as I won't need very much beside clean chorus, lead guitar, clean delay guitar..

The only normal reason for the distortion to zero the signal is because the effects loop is activated (if the unit isn't faulty)
(I have a 9050 and I'm assuming the 9030 also has the effects loop for dirt)
Maybe it's setting itself for external on the distortion patches, although you'd expect a reset to fix that
Also, the distortions in those are analog, so maybe there's a fault but only in the analog section
Could explain why it's only patches with distortion settings that fail while other patches are OK

Great insight thank you :)!!. Can I assume the second board is the analog section or the loop is short circuited in a way?

Not sure about a short circuit, I'm not really a tech but it might be a failed component on the analog board
I know the Zoom 9002 has a common failure because some cap eventually fails from age...there's a fix for that (I have a dead one here)
Maybe the 9030's have a similar problem with aged caps but I've only heard about LCD display failures which is fairly common

Solved. I bought a GT-1 early late November - Early December!
