ATG Mark I-V
Unfortunately, there are a limited amount of photos of these instruments. It has been fifteen years since their inception. Several have been cannibalized to build the latter versions.
My first ATG, the Mark I, was a behemoth a 4-inch x 4-inch x 8-feet wooden beam fitted with turnbuckles for tuning and supported by altered snare drum stands. At eight feet it weighed around 40 pounds. It was actually two side-by-side “guitars.” Each had active EQ pickups. One side contained bass pickups and the other contained guitar pickups. The bass side used single 18-gauge wire and employed woven garage door cables for extreme low-end percussion. The guitar side utilized single gauge wire ranging from 18 to 24 gauge. It's neck was 5 feet, bridge to bridge.
The Mark II was the same instrument cut to fit in a travel case. Its length was allocated by the width of a storage area of our tour bus. This was the instrument I used with Pigface. Still a monster in size, it shut down several PAs with its low end frequency sound waves.
The Mark IV and V are the ones that I now possess. Having stripped the components from the behemoths, I welded streamlined frames. This cut the weight and mobility back substantially. They both fit into PVC tubes for transport and weight only a few pounds. The difference in design was important as they can now be played with a cello bow.
