MATSUMIN: Valve Caster

Just realised that I never posted a regular vero layout for one of my favourite guitar effects - the Matsumin Valve Caster.

It doesn't require power filtering, so you could easily drop the 100ohm resistor and 100u cap.  The Valve Caster was one of my first builds, and it doesn't have any power filtering and is super quiet.

Hi Colin - I still haven’t got around to making an amp. Might just be another giant rabbit hole for me.

There’s a few layouts that I forget that I’d made and never posted. This was one of them.

Good Today, one time i build Valve caster with 12ax7, but its doesn't work. Which layout is verified? Best regards 🤘

Hello. A 12AX7 is the wrong valve. You need a 12AU7 for it to work.

Hi, i have also 12ax7 valve it doesn't work with this layout. How did you do this? Best regards

Is it possible to use 12ax7? I have one from one old project and just wanna use it. Best regards

Nope - a 12AX7 will not work. Has to be a 12AU7, as it can run on the low voltage.
