Funny ad, but the amp looked interesting.
A quick google came up with this: http://www.rissonamplifiers.com/ Risson Amplifiers are designed and built by master engineer, Bob Rissi.
After leaving Fender in 1967, Bob became Director of Engineering at Rickenbacker, where he designed the famous TranSonic series used by Led Zeppelin, Jeff Beck, Steppenwolf, Cheap Trick, Strawberry Alarm Clock and many others. Bob left Rickenbacker to start Risson in 1970, where he built a variety of models that were purchased by renowned musicians like Slash, Lita Ford, Poison, Motley Crue, Al Perkins, Glen Campbell, Rick Vito, Joe Walsh, Rick Nelson and countless others.
My first tube amp head was a Risson ETA 80. I bought it at a Torrance Ca. pawn shop for $260 when I was 15. It was kind of like a JCM 800 with 2 6550's and more gain.
Check out the eBay ads. Seems this guy has stored half built amps for "decades" (the builder, not the guy who posted the ad) and has slapped them together now to sell on eBay. Just put Risson is search under musical instruments. He's trying to sell 112 "half stacks" for $2300. Oh myyyyyy.
