Agreed. I’ve played a couple of Dynasonic guitars with trestle bracing, and it wouldn’t be my first choice. OTOH, with Filtertron pickups, trestle bracing would definitely be my first choice. Even a big guitar, like my Gent, can twang like a Tele on the bridge pickup, yet warm up nicely on the neck pickup. Both pickups is a nice, crisp sound, and the feedback resistance is very nice.It depends on the pickups and the material. I think FilterTrons benefit from trestle bracing. They're bright for humbuckers, but still not single coil bright, so I think the trestle bracing adds a little focus to the tone. And a trestle braced FilterTron Gretsch is a great rock guitar, so the little bit of extra sustain and feedback resistance is handy too. For clean, twangy Dynasonic or HiloTron tones, I'll take a wide open hollowbody with nothing but parallel bracing under the top.
If they work for you, that‘s good. I have one soundpost Gretsch, and in fact I played it just tonight. Good axe.I have two MIJ hollowbodies with posts. Sometimes I wonder if I’m missing something not having the trestlebracing, but they both sound great and do well at high volumes on stage.
There was light and heavy trestle bracing back in the late 50s I believe...to which loudnlousy alluded. I believe my '59 Tenney has heavy. The only difference between it and the modern trestle bracing that I saw on my now sold reissue 6119-59 was that on the modern guitars the trestle legs connect to the back of the guitar and on my old one the trestle legs sit on little feet of wood.This explains bracing types: https://www.gretschguitars.com/support/specs-explained/bracing
Tone is more than bracing alone. Thickness of the top(3-ply vs 5-ply) is a factor too.
I don't have a preference but I only have experience with trestle and sound posts.
While I'm here...what do they mean with heavy trestle bracing? Does it mean two kinds of trestle bracing, or is it used to differentiate from ML bracing?
