Hey thanks Man! :) like I said it's based off the standard noise swash with some of the rack mount swash sprinkled in.. everything works now, including my custom CV control and LFO.. the switchable mixing is pretty dope too.. with a guitar input the resistor mixing is bananas as it mixes clean signal and motorboats and does weird shit.. the diode mixing is rad for self oscillating no input mode. It's a really fun device.

I've just taken a step further down the rabbit hole ;)

From buying complete kits to buying a load of components and some stripboard :)

I'm going to start gently with one of two DE schematics on Guitar FX Layouts, either an LP or OK as they share a lot of components.

If I manage to get it working then I'll try something a bit more adventurous.

Built a Model-T preamp based off the 1974 schematic. Zack from tagboard did a layout and it's pretty good. I modded it just a bit to get my Jfets to bias up. Used J113's, they sounded meatier than the 201s. I also am messing with the input resistors which are only present to remove RF noise in the amp. I may go with some toroidal chokes I got from China..

Also I always like reverse audio taper for gains so I got 2 C1M pots coming before I finally box it.

The model T has this mystique that surrounds it, but it's not so different from a Bassman with a few values changed and a presence control.. it sounds beefy dimed though.

Anyway heres the box, I have been using "Decoart Craft Twinkles" sparkle/glitter paint for over the top glitter shenanigans and it really sparkles. :)

Got some new boots at Cabelas .. stopped into Joann fabric and got the rest of the Decoart Craft Twinkles colors. So dope. Going to start drilling a custom enclosure tonight .. It's a surprise build that I've been pumped on for years. Steel enclosure though.. glad I bought some new bits.
