It's been a while since I've seen one of these and I know there has to be a lot of people with a setup they enjoy.
Over the years I made the progression of stock RB1 -> ION setup like RB -> ION with various parts switched. Played a lot of RB drums... a lot. After moving across the country with my girlfriend in late 2010 and not playing drums until summer 2011, I started pro drums for the first time on this:
I used a stock RB1 kick with attached Pedal Metal and the ION brain and cymbals but added the Yamaha DTXpress IV racking and pads I bought from my brother before the move. From there I slowly added pieces in and took others out and moved them around to experiment. I found out about and bought the MIDI adapter in February 2012, the same time that apartment building caught fire and we lived at my friend's for a month. Big place for one guy, he had an entire unfinished downstairs... so I setup my tv and drum set down there and finally messed around with using the Yamaha brain. In March 2012 we moved back across the country again and I messed around with the kit for a little while in the apartment we had. Now we own a house and I have good space in my home theatre room for my set to expand a little:
It's been a fun and expensive five years. Post away!
