Ah I read about that - you can jumper pins 1 and 8

So... I have the same noise into either valve pre with two pedals... both with charge pumps. One is a John K Mini XO that is all gain and fizz anyway so you can't notice it unless you're listening... Mini XO uses LT1054CP - freq between 15 and 35kHz - typically 25kHz - so at the lower end that would be audible... The Vong came supplied with a ICL7660s which is min 5kHz, typically 8kHz ... 8kHz is about the sound I am hearing! so I need a TC7660HEPA or TC7660HCPA Mouser and Farnell have it - if anyone else has got a supplier that stocks them.... And given that I may have to pay a fairly large postage on one IC if anyone else with a Vong would like me to buy and post out to you... I mean the ideal is I test it first but...

I will report back

It’s the charge pump in the Vong I think

Question… and you may need to point me somewhere better to ask i have a schalltechnik Vong Filterung pedal I built sounds great, utterly silent in use i have a sushi box London Underground and a similar diy valve pedal, 200v plate voltage - sounds great and both pretty silent in use. put them together, in any order and there’s a high pitched whine. Separate power units and still happens. what’s going on and how can I bug fix? if I stick another preamp buffer between I can partially, but not totally filter it out. I thought I was impedance but it happens either way around.

Looked it up, less than 75ohm according to this https://www.creationaudiolabs.com/redeemer anyway I think I 300 as 300k so my misreading. I currently finding a valve preamp pedal into a 10M input isn’t great!

I can’t imagine that it’s that high!

it’s the one that says Vong

If you like my coffee joke I have a spare sticker … though if you did that enclosure for the subsonic filter you need nothing from me!

There you go, send your broken one to @lidl e and he will post you back a fixed one!

Comment on Cioks: they are polish and things get lost in translation sometimes Not a comment on Cioks at all but problem solving: Does the DC7 still fire up? If the model Fet has a hot/burnt smell and failed in some way could it be a failure in that pedal, which could be causing a short that has then heated up the DC7 too?

To be fair to them they have to be defensive a wee bit - they don’t want to accept liability and then have you turn around and say that you had a £5m neve desk powered by it and they were now liable for repairs or something. we’re you putting too much voltage into the model fet or something?

Depends…. https://kmraudio.com/products/universal-audio-la2a?variant=44941668090148&gclid=CjwKCAjwp6CkBhB_EiwAlQVyxUpHbcySo41xA1SvVY7Pg1U3z6Qptmph33lBjApnzDbzkPLS9g9NuRoCtZoQAvD_BwE …

If you are thinking Bass cab and amp direction one of the LFSys models and a clean sounding bass amp might work for you

It's not a DIY effect at all but thought this would be the place where gut shots of a v2 colourbox would be appreciated ... lots of things going on in there. And no I couldn't work out what the HPF was doing to work out how to mod it...

@jimbobothy warned me not to use too much - I’ve got 4 squares about 5*15 MM per pedal and it’s more than enough

What does “a little tired” mean, what do you look for in a good on board preamp? What (if any) extra control do you want? what preamps have you liked in the past and why?

It’s crying out for the top of the body to be shaped a bit like this ACG and follow the “bite” shape!

Fairfield barbershop on that list too… the SFT is literally a SVT circuit with transistors - I built a clone of one years back and it was very nice.

and matches the berg amp!

Nice! It looks lovely too

Ampeg and Line6 are both part of Yamaha so they probably would say they have more fully featured options in their portfolio

Neon pink LED under lighting?

how common model is it? will somewhere like ishibashi likely get a secondhand model in?
