Was just going to post the same thing., great group and Jon has posted lots of helpful information. Here's a video where he shows to setup things on the Stomp for a dual-input bass, The main 'trick' is to pan the inputs fully left or right on the 'split' at the junction between the two audio paths:

Cioks posted an interesting video about using one of their supplies to power a HX Stomp (among other pedals), and also show the exact current draw of the Stomp also:

I stand corrected, the Two10 was 12 ohms at that stage (before I installed the 12/4 switchable option).

I did use a Two10 (8 12 ohm) + One10(8 ohm) in (loud!)rehearsals for a bit, but ended up just using the Two10 as it sounded like the One10 was being driven too hard in that combination; both cabs received the same amount of power, of course. If you are running at a lower volume / power level that results in the One10 not being driver so hard (and also really sounding like it's being driven hard), then using both cabs might work, but for me I wasn't so keen on the sound. So now I use the cabs separately, and I also fitted the 4/8 ohm switchable kit that Bareface provided. The One10 is absolutely killer for something I can carry via tram or taxi - we have no car - and easily fills a rehearsal room or small cafe-sized gig room.

Lachy Doley, a chap from my home town of Adelaide in Australia, is worth checking out. He's a great Hammond / whammy clav player + blues singer: https://www.youtube.com/watch?v=-HkuI3EOBCk

My favourite example is this ('Heartbreaker' isolated bass part): https://www.youtube.com/watch?v=vULgqDEDbiY&list=PL93E8111846B6E16F&index=2 Sounds pretty wretched, by itself, but in context sounds amazing. I played part of this track to my wife, who knows a decent bit about music, instrumentation and bass, and she initially thought it was some 'idiot who sounds like crap doing a Zep bass line cover'. 😄

A good video if for no other reason that it reveals a lot of 'classic' bass parts in isolation sound like a mess of string noise, fret buzz and unbalanced tone, yet in a mix they sit perfectly and sound awesome. For a bass amp / cab noob like myself mucking around on a Helix Stomp it's quite a lesson on NOT setting up patches that round and full through headphones at home only to find they disappear or don't suit in a band mix; better to try and get something similar to these isolated tracks that, while not perhaps 100% satisfying to listen to at home, sound much better in context with drums + guitar etc.

If you have an iOS device, I can recommend one of the 'drummer' apps by this developer: https://itunes.apple.com/us/developer/lumbeat/id590278231?mt=8 I have the Funk, Rock and Soft apps; each comes with a bunch of pre-programmed patterns, or you can enter your own, and each one has a 'jam' setting that determines how random the patterns becomes (but in a completely musical and interesting way). There's an overview of an older version of Funk Drummer here: https://www.youtube.com/watch?v=Vdfi7kwfmF0

I wasn't sure where the best place to post this, so here goes - there's a 'new' CV 60's P for sale in a music store local to me in Tallinn, Estonia: https://stanfordmusic.com/en/products/guitars/bass-guitars/fender-squier-classic-vibe-p-bass-60s-owt-bwb-detail I've seen it on the floor on a stand, but haven't played it. The people at Stanford speak / write English, and claim to ship internationally. Might be worth a punt. If someone is dead set on having it they might want to see if they can put it on hold and then I can go along and check it out; for all I know there's a good reason it hasn't been sold after (presumably) some years, but the market here is quite small and a bit weird in terms of what sells and what doesn't.

@GisserD - Thanks for posting this patch. I received my Stomp yesterday, and was struggling to get some cleaner sounds with it - the vast majority of the bass presets seem to be angling for the 'driven tube amp' tone. Using this patch as a starting point I've already got a few great sounding variations (essentially just changing the amp / cab model, and modifying the cross-over point) to use at a jam tonight. Awesome!

Supply current is one attribute of a power supply, but only one - if you are drawing too much current from a power supply I can almost guarantee the supplied voltage will drop and that the regulation of the supplied voltage will be less than optimal. IMO this device would be much more useful showing the actual voltage being read too; without this the current reading alone is nowhere near as useful. Regarding the 'wildly inaccurate ratings', manufacturers often overspec the current ratings on the safe side, or they know that (for example) digital pedals may draw a lot of current when they first start up but have lower drain after that. I doubt this device has a 'peak hold' function, so it might not capture important information even about the current rating.

I purchased a Tech 21 Sansamp Deluxe VT pedal from David, which was exactly as described, and appreciated the care he took to ship to me in Estonia. Thanks David!

It depends on what you mean by 'tracking'. Do you want to: a) generate a control voltage in proportion to the perceived pitched of the input signal? OR b) do a simple division (eg octave down) or multiplication (octave up) of the input signal? I did mix up these two in my previous comment, apologies. My understanding with the Pigtronix pedal is that they are doing a), and to the best of my knowledge this hasn't advanced beyond the level of the Korg MS20 (for one example); the technology here is a couple of decades old as the limits of what you can do with analog processing had been reached already back then. I'd be pleased to be corrected if I'm wrong, however anyone coming up with an all-analog pedal that does a) will do no better than what has been done previously in terms of tracking accuracy and latency. With something like the EH Microsynth, it has various stages that filter the input signal, and then what I guess I'd call 'mathematical' circuits that detect the pitch of the input signal and then divide it for the octave down or multiply it for the octave up; this happens in essentially real time, so the latency is as close to zero as you can get. So, yes, what you wrote is correct. The big 'but' here is also what you wrote, i.e. the tracking is not perfect and can track the octave (or other!) harmonic of lower notes instead of the note itself. With digital pedals, they are simply applying DSP to the input signal so there's not really 'tracking' involved, hence why pedals like the POG-series can deal with more than one note at a time and track more accurately ('perfectly') than (say) the MXR Octave pedal (and many other similar designs). An interesting design is the Future Impact pedal, which based on a reading of the manual has both a 'mathematical tracking' section (with very low latency) and also DSP-based pitch-to-frequency section (with higher latency).

No matter what, all-analog synth pedals will have issues with tracking accuracy and pitch-detection latency. Guitar-based demos are very misleading from this point of view, as the pitch detection latency is proportionally less the higher the pitch of the source material. For consistent latency that is pitch-independent IMO it's better to stick with the excellent synth sounds to be found in modern digital pedals or to use outboard (iPad / PC) based processing. You won't find much or any improvement after the release of the Cockerell-designed EH Microsynth in the late 70s in these areas, or at least with the pedals I've tried (admittedly not the one under discussion but the latency is clear to see/hear on the bass demos of this pedal).

Likely not -that Xotic device can only provide a maximum of 80ma, whereas the adapter supplied with the Eden chorus pedal has a capacity of 400ma; whilst there is no exact information (why not? lazy effort Eden!) on the current draw of the pedal it's unlikely they would provide a 400ma-capable power supply unless the pedal actually needed most of this. It's also important to note that the pedal + power supply are DC centre-positive, not negative as on the vast majority of effects. Again, a poor effort from Eden IMO, there's no good reason why this should be the case. So if you use a different adapter you'll need to make sure you can flip the polarity, and if you do try any voltage doubling advice be sure to use a polarity reversing cable. The extra power supply thing was annoying enough for me that I built up a cable with a 15V voltage regulator wired up, so I can now run the Eden pedal from the 18V outlet of my Strymon supply. People should also know the pedal is not true-bypass; it has some kind of FET or transistor bypass.

It seems that a non-modded MXR EQ is pretty wretched, noise-wise (see video below). Also, it's non-true-bypass, in case that makes a difference. Source Audio make a good EQ with true bypass, has a few (slightly fiddly to access) presets: https://www.thomann.de/gb/source_audio_programmable_eq.htm

The support guy didn't get back to me as to actually when the firmware update would be released, but someone on talkbass deduced it was 'February or March' from a NAMM video where it was also discussed. Here's hoping!

I've got a GK Plex preamp, and it's been a bit noisy with what sounds like switch-mode power supply noise using the provided adapter (rated at 9V/1A), so got hold of a Strymon Ojai R30 supply, which has multiple channels rated at 500ma of current. Enough for the GK Plex, which has a 500ma @ 9VDC requirement in the manual, right? Not so fast... after some experimentation and back and forth with both GK and Strymon support, it turns out that the Ojai 'ramps up' it's voltage to the connected pedal in such a way that the Plex won't 'boot' properly'. By this I mean the Plex ends up with most or all of it's indicators lit up, doesn't respond to the footswitches, and doesn't make any sound. Using a current-doubling cable, that combines the current from two of the Ojai's channels, makes practically no difference. The GK support chap wrote this: ---- The issue is the power ramps up when you turn on the Ojai. I've discussed this issue with Strymon and they confirmed. If you plug the Plex in after the Strymon unit has powered up to it should work fine. We are working on a firmware update that will allow the Plex re-check for full power a few seconds after it is connected. This should address the issue. ---- So, good news, once the firmware update comes out, but meanwhile the Plex will only work with it's included adapter; despite what he claimed I couldn't get my Plex to work with the Strymon supply, no matter what. Oh, and GK support confirmed this firmware update will also change the 'double-tap to tune' functionality, which is another positive change.

I purchased a Two10 from John, and not only was he kind enough to deal with the extra hassle his end to print and assemble the shipping documentation for it's trip to Estonia, he also packaged the cab in such a way it was essentially impossible for it to get damaged. A good bloke to deal with. Thanks very much, John.

You might find the crackling pots clean up with a number of rotations. For the sockets there could be a layer of oxidation on the contacts; inserting and removing a cable / plug a number of times could well take care of this also.

That pedal is in the same class as the EH Microsynth and other similar pedals - it does basic frequency division / multiplication on a filtered input signal; it doesn't actually convert the input signal to a control voltage as is the case with the pedals you are talking about here, so there is no latency.

"No latency' is a lie - it's impossible. The manufacturer says as much in the comments in the video, but I guess "with no latency" for analog pitch detection in the video title gets people's attention better. The best results I've had with Pitch -> Voltage conversions has been with Harry Bissell's reworking of a Bob Moog circuit, there's a full DIY version out there somewhere.

Pitch -> CV conversion for bass is inherently difficult / 'slow' / unreliable, and in my experience practically unusable for timing-critical bass parts (i.e. almost all of them).
