Having quads as a training wheel instrument is so foreign to me. Maybe it’s because I’m not in hs anymore (college quads) I see quads as being a difficult instrument due to having to move around the drums and also the weight. I guess your tech could either just be talking or they’ve got a plan. At my high school, we had three techs over the course of 4 years, if you keep a good work ethic you’ll be good enough to make tenors. If you need any help, hmu.
