This used Electro-Harmonix Lester K Stereo Rotary Speaker Emulation pedal is in Very Good condition with modest signs of handling and use.  

FROM ELECTRO-HARMONIX:

The EHX Lester K uses stereo outputs to provide a lush, realistic sound with either stereo or mono inputs. Tube-style overdrive is variable and the speaker balance can be fine-tuned. Switch between adjustable Fast and Slow modes to achieve that iconic sound when the big cabinet ramps up to speed and down.
