I just put a set of old Evah regulars on my bass. I like the tone for both pizz (Belcanto'ss pizz is not my thing) and arco. I want to make sure that when I order a new set of EPs I get the best for my needs. How do the EP Weich compare to the regulars on the following points?: Volume tension for pizz ease of bowing / tension under the bow How's the thickess on the EP Weichs compared to the Belcantos? Last, my bass stays in tune for days, but I've put the Evahs a few days ago and I still need to retune several times on a practice session. I've read that they need to settle for a week or more. Do they keep in tune after this period or should I expect to retune too often?
