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...

All true...

Just showed that pic to the wife and all she could see was all the wiring. Must tidy it up...

Ashdown didn't help their cause by writing a rating of 100w on some of these - mine was 100w, 4 ohm, but they are 300w. They're a nice cab. WAY heavier than advertised, but great vintage tones out of them. 20 was the number I had heard. If it starts to sound like it's struggling then turn it down.

AD5144ABRUZ100 I think it is (phone autopredicted that so assume it's right!). I hadn't given the current handling much thought to be honest, but for the initial project I think the 5 odd volt limit should be fine - it definitely won't work for every pedal for that very reason. I got lucky in that the Guma Antique I plan on grafting this to uses 4 100k pots, 2 lin, 1log, 1 inverse log. These chips are +/- 20% tolerance, again I'm going from memory as it's been a few weeks since I selected them and haven't looked at anything other than the i2c section of the dataset and the pinout since, but if they are that's same as the ubiquitous 16mm Alpha pot that seems to be used in most every analogue pedal nowadays.

That's great news. Keep us posted!

Somewhere between £320 and £350 would be my guess, but we'll see.

See my post above regarding the real terms price disparity of the Q-strip... Maybe it's a special case along with the amps - although I think the amp pricing basically says "we don't want to sell these outside the US".

Unlikely...

That was my first thought too... I would have thought for their first foray into the world of bass there would have been a balls out, fire breathing, all valve, loss leading, monster of a head with a ridiculously large cab, just as a statement of intent. This may be more practical, but it's a bit... safe...

So did I, hence why I set about doing this. I wanted to learn a bit more about coding with Arduinos/microprocessors too, so killed 2 birds with one stone, so to speak.

Initial thoughts... Darkglass Vintage Microtubes clone... with presets... But it should work with lots of pedal designs. It is restricted by the voltage the digital pot IC can handle and the configuration of the pots required. This one has 4 100k ohm linear pots (linear, log and reverse log responses can all be handled in software though). But a mixture of resistances would need more ICs which would get difficult pretty quickly. More of the same resistances should be easy as you can chain ICs together. Available values are restricted too - 10k and 100k seem the most popular, although you can get 200k and 1M just not in this device type as far as I'm aware.

I bought an Afterburner 4 just before Christmas to fend off D-Bird GAS... Seeing these pics... It hasn't worked....

Current project on breadboard. Not so much an effect per se, at least not yet... but certainly related! Arduino Micro controlling 0.96" 124x64 OLED display, quad digital pot chip and 4 status LEDs. Inputs from single rotary encoder (with push switch) and 2 momentary footswitches. Foot switches are notionally for bypass and selection of presets. LEDs for bypass state and current/next preset indication. OLED display for preset indication and menu structure for modifying and saving presets to Arduino EEPROM using rotary encoder for navigation. All sorts of possibilities with this!

Ha! Missed the Parkside logo before or i would have known! Don't often be in Lidl, but I'll get my folks to keep an eye out for ext time they're in stock.

I don't usually go in for natural Fender-type basses, but that looks wonderful! Health to enjoy! On a related note, may I ask where you found the soldering iron stand with the magnifier and solder reel holder? Want!
