[quote name='Stylon Pilson' timestamp='1456334690' post='2988023'] I get what you're saying, but it doesn't seem right to say "hey, I've got an explanation, but one of your symptoms completely contradicts it, so how about we just pretend that symptom doesn't exist." I'm sure all will become clear in time. S.P. [/quote] I'm not pretending it doesn't exist - but if it were a problem with the bass, then CamdenRob will have noted the pickup issue plugged in to an amp long before using the recording kit. Everything else, the phasing sound and the doubling effect is a very normal occurence when using audio interfaces with a DAW, usually in it's default settings. - I hope to be able to exclude what is the most usual cause (to those experienced with DAWs) and if the problem still exists, continue to locate it. - Maybe that comes across as confusing, but I blame many years in IT break-fix.

[quote name='Stylon Pilson' timestamp='1456333977' post='2988011'] Software monitoring was my first thought, but: S.P. [/quote] I feel it's a red herring. The 'phasing' sound is a result of two signals, one of which is being delayed (latency) - as the two combined will cause certain frequencies to be cancelled out and others to be summed.

Just had a quick look at GarageBand - on your track you are recording on there is a button called 'input monitoring' - if you enable that setting, that is the sound coming back from the computer (including any plug ins / effects added to the track in a DAW) turn this off and the problem will go away, but you won't hear that processing. The alternative is to find where your 'dry sound' is being added and mute that. Without knowing your full signal path, I can't isolate that straight away.

The way I get round this problem when recording is to turn off any software monitoring on the computer and directly monitor my bass sound *before* it goes in to the computer. For example my interface I use allows this functionality built in - though my recording set up pretty much does away with too many latency problems anyway, I am speaking generally about this issue. You 'll need to track down where the worst part of the latency is occurring.

Ok, this is a familair one. It sounds as if you are hearing both your direct sound and what is called 'software monitoring'. You are indeed hearing a doubling. Your direct bass sound is instantaneous and that is what you'd like when recording. However it sounds as if somewhere you are also monitoring the sound out of the software too. This is subject to latency. This is the time for you bass sound to go in through the interface, be analogue to digitally converted, processed by the computer then back out to the interface to be digital to analogue converted. Even the very best pieces of hardware out there still suffer from this but to a much smaller degree. The worst case is that a lot of effects units that you plug in, even before using your computer are subject to their own latency - add that to the computer's latency and any other 'digital' effects boxes you have in the path too will only compound the issue.

[quote name='Bigwan' timestamp='1456236192' post='2986873'] And a veroboard layout has pretty much been done for me! [url="http://www.sabrotone.com/?p=3173"]http://www.sabrotone.com/?p=3173[/url] Just remove the noise making circuitry from the schematic, adjust cap and pot (and series resistor!) values around the 2 filter stages, and change up the last opamp stage to incorporate a volume control to the design and it's done. Should fit in a 1590b no problem. [/quote] Crickey! That's great!

A very swift and easy transaction from a long standing BassChat member! Thanks Andy!

Happy Birthday chap! Well, i;d also go for the 'birth year bass' - I've just done the same for my 40th. I adore the bass to bits and it wasn't even an expensive one - '76 must have been a good year! Well, Bohemian Rhapsody was at number one as I entered the world. Thanks Queen for writing me such a brilliant song to arrive to ha! Ok, anyway, back on topic - my other choice would be to choose a custom bass! Ok, so it might take some time to actually get it, but how about something special that just screams 'you'. Just a really great bass you won't want to part with. I like that idea.

[quote name='tauzero' timestamp='1455900369' post='2983507'] IIRC that gives a 12dB/octave rolloff for both HPF and LPF - you can simply cascade two identical filters to give a 24dB/octave roll-off which might be better, at least for the HPF if you're looking at thump elimination. [/quote] Maybe that sort of Thumpinator roll off would be beneficial, though for my useage I'd be looking at winding that filer point all the way up to around 300hz - But I don't want to build anything until I've tested the theory!

I recall seeing a post on a P.A related forum where users posted the gut shots of their power amplifiers. Maybe you've planted the seeds for a very interesting thread that quite literally lifts the lid on manufacturers designs. Open up and say "aaaaaaah", the Doctor is ready for his next patient!

[quote name='Bigwan' timestamp='1455795173' post='2982458'] Apologies for the rushed nature of this - just hacked a few old schematics I had together to give you the gist of the thing... [attachment=212628:for dood.jpg] The 11k+Vr2 and 5.6k+Vr1 are a standard resistor in series (therefore setting the minimum value) with one half of a ganged/stereo pot as each filter needs 2 values to be changed equally at the same time. Just need to tack a volume control on the end somewhere to cut the added volume down. Or not if you've got something appropriate next in the chain to do it for you. Edit: Oh and the Broughton just uses a TL074 quad opamp. [/quote] Yup, I understand that! Brilliant! Thank you! In comparison, here's the Rolls Crossover offering HPF, LPF and about 20dB gain boost as I understand it. http://www.rolls.com/pdf/IS_SX21.pdf

[quote name='Bigwan' timestamp='1455739855' post='2982043'] Spent a wee while looking at the Boughton L+HPF and think I have the circuit figured out if you're interested dood. Could draw it up for you. Will be adding one to my own "to do" list! Speaking of my "to do" list, it doesn't seem to be getting any shorter... And just to add to it I've ordered a Mad Professor Blueberry clone kit from Pedalparts. No intention of building the Mad Professor version but it's a good starting point for the bearfoot or bjfe version. A few part omissions and a bit of inventive wiring will do the business! [/quote] You've got the L+HPF? How are you finding it? Yes, yes please I would love to see a schematic for it Thank you so much!
