I just now joined so I can post here.
long time guitar player. started in 1965.
presently I am playing mostly
slide. I play on lap steels, pedal steels, electric and acoustic guitars.
my pedal steel is tuned E9.
one lap, my 1940 Epiphone Zephyr is tuned C6.
the other lap, 1939 Epiphone Century is tuned in open G, sometimes D,and once in open E. it's on loan now.
my acoustic is usually tuned standard but sometimes I tune to open G. my Martin GT 16 really likes that tuning.
my 83 stratplus stays in standard.
my new Highway 1 tele has been tuned to open D.
I use both glass and steel/chrome Dunlop slides. a heavy slide is used on my pedal steel; that's a 1974 Sho-Bud. 10 strings three pedals and four knee levers.
I look forward to reading about what you are into and have discovered.
