The Bugera Veyron Mosfet is the only bass amp close to that requirement: https://www.talkbass.com/threads/bugera-veyron-mosfet-eq-analysis.1459228/

Same here, gutted. 😢

Yes, the original pot for the volume is a 25 kOhms log, but was replaced later with a linear one. 100 kOhms log for the bass and 1 megOhms reverse log for the treble, but again linear one will do the job perfectly with a more useable progression.

You didn't answer @tauzero, but if you solder that 25 kOhms pot between the preamp output and the jack, your bass will found way better than with the non matching 500 kOhms pot...

You could have used the provided rubber clip system instead to attach this Noctua fan (which are the only really silent fans available): it would have been way more fast and easy. 😉 I've done this modification to all the amps with fans that I came across.

Worth checking the early 90's Yamaha TRB Slap Cut series too. 😉

Calling @Andyjr1515 !

So was Hans J. Kullock, who died in 2021, the founder of the MAI in Nancy...

So the volume pot is after the preamp?

You still can wire the pickup directly into the preamp and put the 25kOhms pot at the output of the preamp, so it will work more or less like a real Stingray preamp. 😉

In Brussels, you can try these: https://saibrussels.be/ https://www.sound-academy.co/en-us/ville/bruxelles https://www.iad-arts.be/formations/son In Nancy, France, you can try this, the equivalent of the Berklee College of Music in Europe: https://maifrance.com/

Le Fay pickups are made by the Dobbratz brothers, the two owners of Le Fay. Andreas Richter is now making their preamps: https://www.richter-ee.de/

It's 4 pickups in fact... 😉

Congratulations @admiralchew ! I played a few Ritter's a long time ago at the Frankfurter Musik Messe when I still had hair (and they were very long) and I clearly remember Jens asking me to remove my perfecto brown leather jacket before even thinking touching an instrument... Amazing basses, amazing finish, amazing tone, amazing versatility, amazing ergonomics and amazing look, but I would be afraid to take it outside home... Talking about gifts, here is one, bought brand new, from my wife a few years ago, and not even on a special occasion:

Hélas, Anti, I only have that old Arpège schematic.

Waiting for the message for mine, what is your serial number range?

Superbly done deffreting job too!

I knew that I had the 1982 preamp version schematic somewhere. Here its is @p4ul : And the layout:

Not to frighten you @p4ul , but even Patrice (Vigier), when he was still active, simply changed the complete board as the earlier one were prone to big issues, but it's always fixable by a tech who knows what he does. 😉

Looks wonderful, and at 1424.9925 Zlotys, it's an excellent price for a brand new one. 😉 Congratulations!

There you can find real LM 4250CN: https://elw-elektronik.com/epages/d0dee231-ab0f-4fe3-b9b2-78e23c1b0b52.mobile/de_DE/?ObjectPath=/Shops/d0dee231-ab0f-4fe3-b9b2-78e23c1b0b52/Products/00092517&Locale=de_DE

The preamp from Musik Ding is available by batches, worth checking the site from time to time. The TL061 is certainly the closest replacement for the LM4250CN in terms of sound. There's a difference in tone with the tantalum capacitors, it's tighter with less emphasis in the bass region compared to the usual electrolytic ones. I've compared loads of different iterations of this preamp from the epoxy to the last version. On a fretless, I tend to prefer the tantalum version, but with flatwounds on a fretted bass the electrolytic version is just fantastic.
