Aha, having the bass and treble control on a stacked pot instead of the mids and mid fq (what peavey did). No need to drill extra holes. I did not think of that. I should be able to source one of these from a European seller, too. Thanks !

Yup, a friend of mine had really bad luck with some OTAs he paid good money for. Banzai is super slow, makes so many mistakes in orders and sells fake shit. I suppose the only reason they are still doing business is the huge variety of products they have.

Difficult to find a concentric 50kB and Dual 100kC with a center detent

Last week I got a used indonesian Cirrus BXP (left) for 140 €. I did some basic maintenance and setup . Its preamp was noisy so I built a little something on vero. The millenium preamp with the parametric mids. Schematic can be found here...

Thanks André @disssa and JohnK @johnk_10 for the inspiration !

Yup! Thanks for collaborating with the other TBers and delivering the schematic above !

Hello all, I used the Peavey F800B schematic uploaded in talkbass to design a pdb . Got is fabricated and built it yesterday. Must say that it is a quite squeeze and my poor planning with the eagerness to finish it did not help. I was not sure about how to power it so I built a vero based on a...

And there's more coming along...

Local electronics store. They had around 20 pcs in stock for a euro each a year ago. I was not aware of the unobtainium status. I should have bought them all. Nevertheless, I found out LF347 also works well as a replacement. That's so cool ! I came really close to buying a rack like you...

I have some history with Peavey products. I auditioned for a local band four years ago. Eventually they didn't choose me as their bass player but I managed to snag a Peavey mk3 bass head they had in a corner collecting dust. "Broken, Something smelled burned inside. 10€ and its yours" It seemed...

Yup, that's me sharing the EDB-1 schematic from the unit I traced.

I have the schematic for this one ... Funilly enough I contacted Peavey customer service to ask for the schematic of their EDB-1 and the guy on the other end of the line told me that's the closest match to what I was looking for.

You are right @lowpitch ! Thanks for noticing. I recorded a sloppy demo to send to my friend.

Fast forward 3 months later ... I have designed a PCB for this circuit, got it fabricated and built the pedal. As @Blackboarcult mentioned Vol2 can go to signal out. I have only heard the actual circuit from youtube videos so cannot really compare but I would say it sounds pretty damn fine with...

Perfect ! Thanks a lot !

Good job , John. Very inspiring. Would you mind sharing the schematic for the PS and the filtering section ?

Thanks for the reply ! I have updated the schematic according to your suggestions , tried to make it a bit more compact , added decoupling caps on the ICs and did some other small corrections. Now to design the PCB.

Thanks for the encouragement fellas. I can follow your suggestions @Blackboarcult and give it a try . I am just wondering R12 is 22 k and R14 is 270k. Do they really form a voltage divider ? (honest non-sarcastic question)

Hello everyone, A friend recently reached out and asked if I could clone the Ampeg SS-150 preamp for him. I found the schematic of the SS-70 (the combo version) which sports the exact same preamp as the SS-150, just a lower wattage power amp. pic1 The preamp has two channels and jfets to...
