Finally, the knobs have arrived. At first, I was sus as to why the package was so big? Big as in A4 size? Did I order a lot by mistake? It turns out that these friggin’ knobs are guitar knobs and not the ones I wanted which was about 1/3 of the size. Shows how […]

20260330 Razor Crest The Reminder
OK, this is one of those Projects I’ve let it simmer for quite some time. I meant to pick it up after our Move to another place which I can say, is finally our very own Home. But that turbulence only settled last year. I have put the Project away and once in a while […]
