As with previous incarnations of the Pandora, Korg's propriety
REMS modelling technology is used. The device is mainly driven
with sole purpose control knobs although changing parameters
in effects etc. require use of simple menus.
A useful phrase trainer is provided, as are basic drum and
bass patterns for practice, whilst the aux in jack allows connections
to external CD, MP3 or other audio sources.
In summary and after a few months of use I find the 4D is extremely
useful. Its small size means it can fit into almost any instrument
case and can serve extremely well at jams, band practice, and
for silent late night practice at home with headphones. Its
chromatic tuner function, with its large backlit display also
makes it excellent for tuning up when changing strings or maintaining
your instrument even in dark locations.
Sound quality is also excellent with a good selection of effects,
as well as amp and cabinet models, although not on par with
more expensive modellers but nevertheless good enough for the
range of intended applications for this device.
