Dec 11, 2024 · Without really thinking about it I looked at the PCB, saw three diodes in what could be a asymmetric soft clipping configuration, along with op amps and a 1Meg trimpot for adjusting the boost and jumped to an SD1 as the basis for the design.

Mar 29, 2024 · To be fair, I think JAM pedals have done something more than just use a boost based on a Tube Screamer. It looks like asymmetric clipping, and two op amps (TL072). I had the opportunity to play this one of my mates, for me the boost at full was way too much, so we took it …

Jul 20, 2020 · I briefly owned a JAM Rattler (damn you, covid) and I loved it. How does it differ from the classic Rat circuit? can any old Rat pcb be modded to be similar?

Mar 6, 2025 · Does anyone know what Pro Co has done to the RAT to make it a FATRAT? I'm talking actual circuit and/or component changes not sound/features. If anyone has any gut shots or an actual verified/traced schematic that would be great.

Ratt Deluxe is the best-sounding and most versatile RAT PCB you will ever need. Of course, you may always hand-wire the pots instead of board mounting. With SIX multiple clipping options (see our Clipping Chart in the Build Document) and our version of …

Sep 27, 2023 · I’ve been liking the sound of the Jam Pedals Rattler and was considering trying to make a version of it. Their website says “put in the time and R&D to make it more responsive to picking and fretting nuances resulting in an open, dynamic, overdriven tube-amp feel!”

Nov 30, 2015 · This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts.

Nov 17, 2024 · I've always been into the RAT sound, but this thing is on a whole other level. They boast quite a bit about their selection of NOS components as the secret...

Jun 16, 2024 · My pal wanted a Rat clone. I made it for him today. I’ve got to make an enclosure for it but maybe next weekend. I’m pleased with the layout and with how it sounds. This is the second Rat PCB. I laid it out better and left room for larger components. It’s less noisy. What chip are you using ? What clipping diodes ? What chip are you using ?
