....They came in the post today! Whacked them on the bass, and had a bit of a scrape and a pluck.
I was quite surprised how thin the g string is in diameter, but the rest of the set seems fairly standard in this regard. They certainly respond very well to the bow and put out a lot of volume. The sound is extremely focused and is at the moment on the bright side, I think I'm going to remove the baroque style bridge (heartless and wingless, Gerold's response upon receiving a photo of it was 'without heart - how would you like to live without one?' - Seriously though he did express concern about the suitability of the sound for orchestral playing, and now I have his strings on the bass I'm inclined to agree with him) and put a modern style one back on to tame a bit of the zing. The thinking behind that whole experiment with the bridge was to try and liven up the sound, and I can see that now I've got some strings that really work that this is unnecessary.
The lower tension feels great for both hands, my bass has a 43 inch stop and a chunky neck. It's tiring to play at times even running fairly user friendly strings like Belcantos, Passiones, etc.
I imagine it'll probably take a few weeks for the strings to really settle in and for the instrument to really adjust to the lower tension, and I'll report back once a more sensible bridge and the RED SONOPHIL tailpiece wire have been installed. But right out of the box I think they sound extremely promising indeed, so much so that I'm thinking I won't be going back to any of the offerings from other companies in a hurry. Or ever, really.
I'd be very interested in trying some of the gut strings he offers, but at present I think I'm happy to leave that adventure for another day. Hope this is of some interest to anyone reading all the hype about his strings - from my limited experience I'm already confident in saying that installing a set of Sonores string is extremely unlikely to result in anything other than a significant improvement in playability.
