The Infamous and rather difficult to find, Ibanez BS10 Bass Stack Pedal.
Often these things happen... Pedal is designed and made, interested isn't great and they stop production a few years later. Later, much later, a rather famous player is discovered using the pedal and talks about how great it is... only he's not using it on bass but on guitar.
It's a great Bass Overdrive/Distortion pedal (fer sure) but it's also a bit of a secret weapon for electric guitars.
It's somewhat a quasi Rat style pedal but without the tone control being quite as active/filter as on the Rat.
Part of the Ibanez Power Series or "10" series, it wasn't produced in the same numbers as a Tube Screamer - and you don't see them too often.
This Used pedal is in Excellent condition with only a few small scuff marks - as seen in the picture.
There is a slight bit of dirt/scratch on the Drive control (around 11 o'Clock) but it has gone away after use. Seems that this pedal has been sitting around for a while.
Can be powered by a 9 volt battery or Ibanez/Boss style power adapter (not included).
