The Ibanez AD190 Time Machine is a bucket brigade analog delay in an 'amp top' box.

It has one 1/4″ mono input jack, variable pad switch for the input signal, two 1/4″ mono outputs (dry plus delay and wet only), 

Seven pots controlling input level, tone, delay time, regeneration (feedback), blend and two for a flanger mode “width” and “speed”

This has been modified so that the modulation LFO still functions when in delay mode - so now you can have modulated delay as well as flanging. There are youtube videos of modified units like this so please see there for example of the kind of effect you can get. 

Gets very gritty and dark with long delay times, sounds great with high feedback.
