I’m kind of afraid to ask… It forces a rush of compressed air into the tone wood molecules and makes them vibrate more quickly. As a result the bass resonates faster, making the sound sweeter, generates a more purposeful tone, and thusly the player becomes faster, with improved technique and accuracy, and becomes more God-like. 🤣 You did ask.

Happy Christmas one and all! What if it’s vintage tonewood? 🍿 I’m also assuming that a longer g string screw on the bridge saddle makes it sound different also Edited 5 hours ago by Geek99 Quote

As for that screw in the G string saddle, I’m selling them for £40,000 each. Right, who wants some Magic Beans then..? Quote

The bass came without the correct 6-32 intonation screw (actually a bolt). The original would be 1 7/16in (39mm) long. I sourced some 2in bolts and cut one a bit longer, as I suspected the original had been lost because it didn’t adequately engage with the bridge saddle. This topic is crying out for a PhD thesis! 1 Quote
ezbass Posted 4 hours ago Posted 4 hours ago My J type has Delano pickups, which are actually split coils in a single coil casing. These are wired to a VBT config. I can achieve 5 tonal settings from this, not including the tone control (.100uf) roll off: if 6 o’clock is typical 50:50 blend, 5 and 7 o’clock give either a more neck or bridge flavour of the mid position, whereas anything beyond those points is either all neck or bridge.

That’s the thing, once you back off a stacked volume control or a VVT volume more than one notch out of 10, I don’t hear any further change.

JapanAxe Posted 1 hour ago Author Posted 1 hour ago I mentioned earlier today I had 'another idea' - I've implemented it, and it works! When thinking about what didn't work for me about the stacked-knob setup, the main issue was the tone pot taper, where there was little effect until the bottom quarter turn of the pot. I removed the extra 56nF caps and added a 510k resistor between the wiper and the 'hot' lug of each tone pot, thereby converting the existing 500k tone pots to 250k with a somewhat different taper. The tone pots behave much better! Curent plan is to to stick with this, but also acquire a 3-control plate and build it as Vol/Switch/Tone or Vol/Blend/Tone. Watch this space... 1 Quote
