This is the RODENBERG GAS 909 DISTORTION, also used by Steve Lukather. I purchased it new, but the sound wasn't what I expected, so I stored it for a while. It was only used indoors. I've confirmed it's working, and there are no issues like crackling. There are no noticeable scratches. I couldn't find the original box, so I will ship it in the Bogner box shown in the photos. Please note that the box is Bogner, but the contents are the GAS 909. The instruction manual (Japanese) that came with it at the time of purchase is included. Basically, no returns or exchanges, except in the case of the sound not working upon arrival.
