It's official - I am making the Octavius Squeezer my one and only bass synth. So I'm unloading my XO ehx Bass Microsynth. I'll probably end up regretting this, but that's the way it goes. XO means this is the new, compact, true bypass version. This is an excellent unit. A classic. What else is there to say? Mint condition, perfect function, in original box with power supply and instruction sheet (for some reason, the preset templates were not included, but you can get these from ehx). Original rubber feet on bottom, no velcro or residue. SOLD.
