I’ll pay any amount for what’s considered the best koma on this website, or particularly one that allows for the most projection and resonance. Please let me know if you have an idea! Thanks!
Just get the tallest one.
If projection is what you’re after, higher action is going to lead to a louder sound. It’s also going to be harder to play, so keep that in mind.
Honestly speaking, koma are pretty minor in terms of overall impact to sound color - but the impact of height on sound force can’t be ignored.
Thanks for the info!
