Evah Pirazzi Slap (Synthetic core E, A + Plain gut D, G) String set (used). I put these strings on my instrument new in January 2024 and used them for almost two years, until last Saturday (October 18th). I used them about once a week (for a 2-hour jazz live performance). (I mainly practiced on other instruments). The string tension is weak, so they are easy to play and don't put a strain on the fingers. The strings have deteriorated, but they are still usable. You can listen to the sound, etc., from the recording (WAV file, about 2 minutes) of the live performance on October 18th (Saturday) below. http://baian.net/251018_evahpi_slap.wav Also, I have uploaded a live recording using these strings to YouTube, so please take a look below. https://www.youtube.com/channel/UCEExc-FMmwd8qqI7Lq3Bu2g According to Soundhouse, these strings are introduced as follows: Evah Pirazzi Slap double bass strings are suitable for rockabilly, jazz pizzicato, and Baroque-style arco playing, which frequently use slap techniques.
