I was recently given this little effects "box",from a friend.My first impression was...hum...just another little effects box with fuzzy,thin sounds.Whoe...was i surprised!The box is the Korg Pandora PX 4.Although it is not the latest of the series,it has some great sounds in it,along with rythems with bass also,and a loop effect.The size of this unit is very small,say 6 by 8 inches,approximately.It has some great tones/ cab sims,along with your typical effects,like auto wah,chorus,flange,delays,reverbs and even harmonizers and an octave divider.The cab sims are very good,in fact some reminded me of the "Redbox" i have used fairly often.The cleaner sounds combined with a "tweed"cab has a great tight,thumpy,low end sound.And the edgy were good also,and when combined with the cab sims were very usable.As for the the more heavier distortion patches,they also were good.The effects like chorus were good but lacked that super "thick"type" chorus,but are usable.And as a plus there are some cool "synth" sounds.Overall,for a "small/very small box,the Korg Pandoras PX4 is a very cool unit indeed.And the cost on- line is around $150.00 US dollars or less!So if you are looking for an inexpensive/great sounding desktop guitar effects unit,check the Korg Pandora PX 4 out,i think you will be pretty amazed also.
