I don't know much about them, but I suspect that Lindsey Buckingham may have used one (or a variant) in the early 80s with Fleetwood Mac. He alluded to it in an 80s-era interview once, but didn't mention the specific brand and model.
Were there other Ibanez models that had echo, overdrive and chorus?
Gonna open it up tomorrow and see what its all about.
The compressor sounds like my old trusted CL9, the one that comes along for slide duties.
I cranked the compressor to goose the TSwhateveritis and it's awsome.
One output is dodgy - bad jack probably, but for 20 bucks its a keeper for my blues sets.
