Alesis S4 Quadrasynth 90's Polyphonic 1U Rack Mount Synthesiser Sound Module

The S4 is the rack-mount version of the QuadraSynth. It's a 64-voice digital synthesiser with a whopping 16 MB of sample ROM, and was the first synth to offer the ADAT Optical Digital interface. It also featured the same multi-effects processor as the QuadraVerb 2, drum kits based on the D4 drum module, 4 assignable control knobs, one PCMCIA card slot, 48kHz clock input, and 4 audio outputs.

The S4 is undoubtedly a powerful and flexible synthesiser capable of creating rich sounds - both acoustic and electronic. It uses digital additive/subtractive sample playback synthesis to create high quality stereo grand pianos, organs, strings, drums/percussion, brass, woodwinds, new and classic synth textures, and more. (Vintage Synth Explorer)

Color is not the same as picture, too light, assembly is harder than it should be
Size: g:Square Table with Umbrella Hole, Color: Light Grey
I had higher hopes for this table given the 80 dollar price tag. The gray finish is MUCH brighter than what is displayed in the picture. What's advertised matched the gray Adirondack set that I currently have in my yard, what came in was about 5 shades lighter. The assembly only had a few steps to it with a total of 8 bolts but it was more difficult that it had to be has the holes didn't line up very well and I actually had to bend one of the metal pieces to get the screw to line up. I ordered this piece initially to serve two purposes, the first was to add more stability to my ever blowing over umbrella, the second was to add a matching table piece in-between my two Adirondack chairs. This piece does neither very well. It is too light in color to match and serve to complete the set, and it is not heavy enough to add any layer of stability. For these reasons, I cannot recommend this piece.

Nice, but...
Size: g:Square Table with Umbrella Hole, Color: Black
Second one I bought. So I do like it, but for the price they could include an extra screw and washer. Also it would be much more convenient if the holes would line up correctly. That's why I gave only 3 stars. But it is a nice table.

Durability
I was very satisfied with the quality of another Best Choice Products: Ice Chest. So, I was happy to see the umbrella stand, weighted by water, was available by this company. It is, once again, made very resilient and strong to withstand tipping over. I'm a happy customer of this company's products!
