Let's just say I'm sharpening my pencil...

The main problem you would have is deciding what is the "relevant range". 30Hz HPF cutoff? 40Hz? 10kHz LPF? 6kHz? Would be easy to make them switchable, but it adds to expense, complexity and enclosure size.

That's what a blue star means in the MS60B download, so probably means the same here.

The MS60b and B3n are different generations of product. By that I mean the B3, MS60B and B1on (and all the guitar equivalents) all use the same hardware/processor. The B3n is a newer design, new models, new everything really. It'd be like trying to run Windows 10 on an old 386. Wouldn't work.

Isn't that what the graph on page 4 shows?

Sorry guys, that came off as a really sarcey comment. Not intended that way - I was finding it hard to keep up!

This thread has turned into a big ball of confusion...

Yes. It's the depth parameter of the Ac Bs Pre effect. Between "bass pre" and "SVT" if the effects appear in the same order as the MS-60B manual. EDIT: seems to be in same place in B1on manual so if they're in the same order on the pedal that'll be where you'll find it.

Probably to closer match his other basses I'd think!

Just through headphones via a little behringer desk so not really transferable to this case Dan...

But if you're using the MS-60B why add an extra HPF? It has one on board anyway...

Been following them on Instagram for a while. They look great!

MS60B has the AC BS PRE according to the effect list on their website. If the effects blocks in the effect list are the same as on the pedal it should be between "bass pre" and "SVT".

Just a hole nobody has really filled. There's also an Australian built passive HPF that is 6dB/oct and TINY, but can't recall what it's called right now... EDIT: It's called the Tight A*se... If there's interest I could build a little run of the Vong filter when it's released. If I had more free time I'd put together a competitor for the Thumpinator myself. It's eye-wateringly expensive for what is essentially (and I'm just taking a wild guess without counting the pennies) £8 - £10 of parts... I might give this a bit of thought... I can think of 4 useful pedalboard tools of varying complexities along the same lines...

A lot of hardware cabinet simulators take advantage of the filter overshoot (the electronic term is ringing - it's a characteristic of the Q, or quality factor of the filter). The OmniCabSim is a prime example of a collection of filters designed specifically to be non-ideal.

This effect is mostly down to design compromises made to allow the filter to be variable. The filter is, as a result, not ideal. The Thumpinator isn't specifically designed to minimise this peak, per se, but the filter doesn't have to be compromised in the same way. The filter design used in the thumpinator has been around for donkey's years, it's a standard electronic building block (see any active analogue filter design textbook for a 4th order Sallen Key filter).

What strings do you use now? Go up a gauge and see if it helps. I went from Elite 40-100 to 50-110 when we tuned down a tone and the bass needed minimal adjustment so tension must have been pretty close. As Dood suggests use the D'Addario string tension calculator, it'll get you in the ballpark.

Unless you're spending super coupons on reproducing the fundamental a 40Hz roll off vs anything lower won't really be audible on a 5 string IME

Meh... all I can determine is that I REALLY don't like Dug's sound in that video. I'd like to hear it with a P-bass played fingerstyle, but my initial thoughts are it's definitely not for me...

Indeed! Chaining 2 of these together will have the same effect (in theory) as a 24dB/octave roll off. That's how these filters typically work, 2 identical 12 dB/oct filters in series.

The B3, MS-60B and B1on have the AcBsPre (Fishman Platinum pre model) that has an HPF parameter (depth by the look of the B1on manual).

For the DIYers among us, Julian Pohler (Mr. Shalltechnik04 - the guy behind the Guma Drive, Guma Antique and Growling Krizzly kits) is bringing out a combined HPF/LPF + DI kit soon called "Vong" (no idea what Vong means). I've asked him to keep me posted on when it's to be released.

Still love my Aria MAB20/5 that I spent most of my formative years playing. Recently dabbled on it a bit and it's sounding better to me now than it ever did! Have to agree with BRX (doesn't happen often!), there are Arias and there are Arias...
