Ibanez 10 series pedals - common problems?
I've recently took out a load of pedals that I had in storage, quite a few from vintage Ibanez, Boss, Dodd, MXR, etc etc... all were ok except for four late 80's Ibanez "10" series pedals. A DL10 Digital Delay, CP10 Compressor, MS10 Metal Charger & a CS10 Stereo Chorus, all of which are just simply dead. No power recognition, nothing. Surprisingly, the one pedal I thought WOULD die was the DDL10 Delay II. But that one is fine.
Is anybody aware of common faults with 10 series being unused for several years? and what are the chances it's just dry joints? shame to waste these classics. They're boxed and everything! meh.
