Rane TTM57SL.  Excellent+++ condition.  3rd generation - superior build!  Original box.This Rane TTM57SL is in the very best pre-owned condition.  This model is the 3rd generation of the TTM57SL with very important upgrades to the design, build and components, including:- Redesigned B Group buttons (for triggering effects, cueing, looping, etc.).  These buttons which are integral to various functions on the mixer are concave and slightly larger than previous generations, allowing for easier and more efficient access to their functions.  As well, where previous generations of the B Group buttons were notorious for going bad and unresponsive due to oxidation, the B Group buttons on this generation of the mixer have been vastly improved in that area and nearly impervious to oxidation.- New and improved potentiometers at all 18 points on the mixer (all rotary control knobs - EQ, gain, pan, output levels, etc.).  These have a stronger, more robust shaft than previous generations and are in general a much longer lasting part.This mixer has been used very little, very gently and only in a home studio environment.  Everything functions as the day it came out of the box.  All buttons function perfectly.  All rotary dials function perfectly, with tight fitting in-tact knobs.  All faders function perfectly, with knobs as tightly fitting and secure as the day it was purchased - That is to say, secure, but not impervious to removal if needed.  Both joysticks in the B Group section function perfectly.  All program inputs, mic input, analog outputs and USB port function perfectly.  Both the 1/4" and 3.5 mm headphone jacks function perfectly.  The 1/4" foot switch jack has never been used.There little to no cosmetic damage to the mixer.  The top faceplate has zero damage.  The graphic lines under the crossfader and line faders are completely intact, evidence of gentle and limited use.  The bottom of the mixer has a few very faint surface marks, significantly less than one would expect on a mixer of this age.  Cosmetically this mixer is 9.9/10.  Performance and functionality are 10/10.The mixer will ship in the original Rane box with original styrofoam supports, insuring safe transport.  Bid with full confidence.
