    Warwick Hellborg preamp transformer question

    I know AML as they are fairly local to me. And seen CAPI - the challenge will be getting them to the same/similar values as the hellborg ones Alternative I guess would be a non-inductor based semi parametric mid control

    Warwick Hellborg preamp transformer question

    I’ve got the basic circuit into KiCad now to build it as a preamp… Thanks to @vigilante398 I know that a neve style line input transformer will get me in the ballpark - so carnhill or cheaper OEP equivalent Output Di transformer is from the output of a 5532 stage - and I should be able to...

    Skeptical buffer introduces noise when harmonics switch engaged

    I was going to ask, did you get the polarity right on those tant caps?

    Relay Bypass – do I really need one?

    Though with a relay in the right place the audio path can be made shorter. One of the oddest things about pedal design is running the signal the whole length of the pedal twice from the jacks to the footswitch

    Jlcpcb and tariffs

    Problem is if you're just selling on the value and place of origin of the product is still china and then theoretically subject to Chinese tariffs. (there is similar issue with EV built in UK using Chinese batteries as more than 50% of the value is Chinese products. What you could do is build...

    Tayda UV printing - what counts as white?

    Typically in print white would be 0/0/0/0 - FFFFFF only works in HTML I don’t know how Tayda works but how I would normally do it is make a seperate layer called white, and then make a spot colour (as opposed to process colours) called white or whatever, and use that for that layer Same with an...

    Adding effects loop into pedal and avoiding ground loops…

    Oh! I thought it would be more complex that that!

    Adding effects loop into pedal and avoiding ground loops…

    I fully realise this will be covered on a thread or page somewhere obvious online that I haven’t found

    Adding effects loop into pedal and avoiding ground loops…

    I’ve searched, I’ve googled and lots of things about isolated power come up… If I wanted to add a switchable send return loop to a pedal design… presume buffer on send and return to avoid any impedance issues - is transformer isolation needed to avoid ground loops? Thinking of combing an input...

    Torso 🪚😱🟨 (Prunes & Custard/Curds and Whey)

    They are awesome - I don’t get changing the distortion bit idea, isn’t the distortion bit *the Wavefolding* bit - and then the diode ladder is after

    Warwick Hellborg preamp transformer question

    Well - first of all thank you Nathan Even if they can't sell something with you, what you managed to find out from them means we can work out what the design decisions would have been.... Its specs as you found are very very close a Neve line input transformer, wired backwards. So either...

    What's on the workbench?

    Going slightly back on topic - I tant it great @Robert has featured a few more bass players favourite pedals recently? Anyone got a 3leaf octavbre to loan him? The older one as the new one sounds a bit meh on a soundclip I heard (plus cult unavailable out of production stuff is the way)

    What's on the workbench?

    while the world is still an uncertain place, I'm glad I am young enough that some things are before my memory and experience. The Miners strike, Margret Thatcher, National Service, The phase where brown guitars were cool, the Cold War and the threat of mutually assured destruction, and now I...

    What's on the workbench?

    No idea who Stryper or Strypre are - before my time! Kilt = Stu G who was guitarist in the fairly obscure 90's band Delirious. or Deliriou5? as I think they styled it.

    What's on the workbench?

    I love the way that the signature pedal of a random British christian rock band I grew up listening too is a desirable thing now! Bear in mind that unlike the States, religion isn't a big thing and "Christian rock bands" have about the same following and cultural clout as skiffle bands do in...
