1 - the GRETSCH = it has a wonderful round, punchy sound, which I must say, I like very much. It reminds me of the 50s and 60s jazz recordings. I admit that You scored big time there Gregory.
2 - the DESIGNER = it definitely has the "modern" vibe in to it. Sound is EQ-d by itself, the bass drum, toms, snare - everything sounds fantastic. It's what a modern bop drum set SHOULD sound like!!!
3 - the TEARDROPS = definitely more timid (and with less volume) than the GRETSCH set. I guess it would be a perfect gigging kit, at least that would be my choice...
So Gregory, when we talk about sound, I guess (for me) the Designer and Gretsch share the same place - but in a different direction. It's fantastic that You have both, because You can either go with the modern sound, or with the vintage great gretsch sound. The teardrops, on the other hand, are mild, non-aggressive, modest = and that's what makes the perfect for a kit for every gig. It would be up to You to give the final touch, regarding how You want to sound, with the teardrops...
I love threads like this. For a guy like me, who'll probably never get in touch with so many kits, they're a perfect source of valuable information regarding sound characteristics.
Thank you Gregory, for sharing these sound experiences...
