Here's a really cool Alesis QS6 keyboard from the '90s that works perfectly and sounds great. This has a new black with white text LCD screen and this comes with the power supply. Features 61 keys (not weighted,) 64 voice polyphony, 16 part multi-timbral, 512 preset/128 user sounds, digital effects based on the Quadraverb 2, pitch wheel, modulation wheel, 4x assignable control sliders, MIDI In/Out/Thru, Sustain pedal, Assignable aux pedal, stereo L/R outputs, headphones jack. A really nice keyboard with great sounds and can be expanded with sound cards that can still be found online. There are numerous videos on Youtube worth checking out to see, hear and learn more about this keyboard. In overall good condition with some signs of use, but nothing major. The button cover for the power button is missing, but it can be turned on and off. It's a common issue for these models. From a smoke free home.

$300 or best cash offer. I will consider trades for other music gear.

This is located in FORT WORTH.

IF THIS AD IS STILL POSTED, THEN THIS IS STILL AVAILABLE.
