Is a high quality nat. gut really more expensive than, say, a high quality multi? Let's compare a premium nat. gut that costs 35 bucks against a premium multi that costs 15 bucks. Ok and let's say that this nat gut retains it's playability/tension for 35 hours (of playing), while the multi retains it's playability/tension for 15 hours. Then, the real cost of these strings would be the same. Actually, nat. gut would be more convenient, because you would have to string less. Is this how this works? Edit: Of course, the above refers to a full nat. gut job versus a full multi job.
