while it's best if your slots are embossed and reed work has been done you can still do a minor but not optimum ob gapping set-up w/ hardly any pain.
for gapping info see choppajoes videos. there are lots of others too.
it's best to be able to see what you are doing so....
remove your cover plates and choose your gapping tool.
if you have a harp like a GM or SP/20 you need something thin like a paper clip, bobby pin, toothpick, etc. this is to get past supports in the comb slots.
i start on the bottom 456 reeds. these are the reeds that sound when you ob, not the blow reed.
gap them fairly tight, but not so that they choke or stall when you draw. it's best to work on one hole at a time.
when those are done gap the top reeds tight by pushing up.
if gapped too far the reeds either won't respond or respond only as an overblow. if they only ob this a good sign. in either case it means it's time to open your gap a bit.
gently press down so the reed will sound it's normal note without choking. now try the ob technique. you have to go back and forth pushing up or down till you get it right for you.
this is just a very general description and only meant to get some obs out of your harp. embossing, using wax, nailpolish, chapstick are things that are debated often.
i'm not going to bother going there.
hope this helps. ----------
