I got a little caught up in the moment, as one can have a tendency on eBay, and purchased a Roland TD-7 Turbo module. I got for a pretty fair price, about $170, and it came with a rack mount tray and all the manuals. I was hoping that perhaps since it lived most of it’s life in a rack it would be in excellent condition, and I was right. . . almost. Apparently sometime after it was pulled from the rack, but I believe still attached to the rack tray, it was dropped. Something must have caught the volume knob on the way down, as it was way off kilter, and jammed against the faceplate.
It could still be turned with a little extra force, but I also found that the headphone jack wasn’t working properly. I was a pretty disappointed, and pretty P.O.’ed, but I tore it down to see what I could do. I often times will tear my gear apart before I plug it in anyway; maybe some of you can relate. It turned out that I could bend some internal framework back into shape and snap the volume pot back together and I was in business. Like I was hoping, the rest of the unit was in pristine condition, so overall, I was happy. The seller played dumb, and I can’t really say if he knew it was screwed up before he sent it, but he wouldn’t even admit there was a possibility, even after I said i wasn’t worried about it. He said that if there was any damage it must have happened in shipping. Too bad he packed it in two layers of the big bubble wrap, plus peanuts.

I have already found in my research that the TD-7 may not be the best solution for making the mesh headed drums I want, but we will see. At the very least it will help me get my feet wet, and I can upgrade the module later, if I find a need.
