The Ibanez UE-300 is a relic from the 1980s when multi effects were becoming popular but predates the popularity of digital effects. This unit has an all analog signal path with a compressor, overdrive (tubescreamer), and chorus all built into one unit with a master bypass switch and effects loop. The pedal sounds great but after thirty years the hardware is a bit tired. This rehousing narrows the pedal by almost two inches and also provides the opportunity to install soft-touch footswitches, all new jacks, a bypass switch for the effects loop, and convert the pedal to run on DC instead of 110V AC. This ended up being a big project but the end result should provide years of reliable service and sounds great!
