I've been buying my first headless 34 years ago and since then have been owning and playing hundreds, really, of headless basses. I never had a problem with the clamping system as long as you cut the strings after clamping them with the needed pressure of the hex screw. I've put some White Nylon's on my Leduc U-Basse 4 fretless and simply noticed that the G string needed more screw pressure when clamped. After that it was staying in tune perfectly and I could detune it and retune it without any problem. Before that, some headless fretless basses have had Black Nylon's without any issue at all, even my sixers. Check your clamping screw, the clamping side must be slightly flat rounded (slightly flat ball shaped to match the pressing point) without any asperity that could cut the string. If you have this kind of hex screws, you are in big problem, so round them much flatter and it will be fine :

🤣

Sadly yes... No packaging means no insurance.

This is what happens when you drill in the dark and fit the tuners when drunk. Or maybe it's a new MDP prototype ?

The mighty 80's best ever cover band. ... I think people will know what it is.

Paris Midi or Vienna Midi are perfect 80's tribute band names.

One finger keyboard.

Nice name for an 80's tribute band. You should suggest it. 😉 I'm kidding.

Already proposed before. 😉

Small County.

Don't Panic.

Nail Varnish.

Dx7.

Simple Ballet.

A Flock of Snowflakes.

They indeed offer the exact same full 30 days satisfaction warranty for U.K. customers, so you have nothing to pay for the return. Their lawyers are true donkeys, as U.K. is outside EEC, a simple sentence would void that free return warranty. 🤦‍♂️

What would be very interesting too is the basses these strings were fitted to. I've also tried almost every strings on the market and have noticed that excellent strings simply reveal the real character of a bass, so a dull bass will sound dull and a dynamic bass will sound dynamic, and so on. There's also another relationship that your tests seem to confirm, but that many refuse to admit, but let's wait for your basses list.

Ask for photos...

If you need the cut, yes, than go for the OBP-2 which is a bit more aggressive, simply due to the faster trace of cut/boost, so a bit more feathered settings are required. 😉

The BTB 575 is an old model from around 2010 that has been quickly replaced by the BTB 675. If there's an N in the denomination, it's certainly an NTF model, which simply means a natural finish. https://thebassgallery.com/products/ibanez-btb-575-mfm https://www.musicstore.com/en_OT/EUR/Ibanez-BTB-675-NTF-Natural-Flat/art-BAS0003145-000 2009 Ibanez Catalogue, BTB series :

Do you ever cut your EQ or only boost it ? If you only boost it, than go for the best ever Aguilar, the OBP-1, and it's a FET transistors preamp, which are way more musical. You'll also have the option of a passive path with a tone control. Best of both worlds.

Thanks for all the information. Here's a photo of the back of this bass, looks like an Energy with some added features, no ?

Excellent work and beautifully looking fretless bass. Congratulations !

It's new for @Cliff Edge, hence my answer. 😉
