Awesome idea.
Hope it works in the cp5 pre. That could make a great combo.

Pretty awesome. Color is just outrageously cool. I can see a tweaker for boost amount and jumpers for frequency. Is there a saturation circuit in addition to the 2520? Something to react more extremely to the input knob on the palette? |

Nice to see the Red Five-20 popping it's head up in public. We're just about to start seeing even more of em....
This looks to be a nice addition to the color palletes....

Something to react more extremely to the input knob on the palette? Hey Noah! Yeah, Colour is certainly getting some great options! You have that correct. The pin header on the left is where you select frequency. You have options for 3, 5, 8, 12, and 16 kHz shelves. You then can control the amount of boost (0-12 dB) with the little HF Boost trimpot. The design is faithful to the original Pultec EQP-1A3SS circuit to a "t" with the exception that I opted for shelving filters (sans inductors, which makes it more like the EQP-1S3) and omitted the input and output transformers. But...you can always put some CTX modules in front of or behind this module and get some transformer vibe in the signal path. Or if you want to add a little tube flavor you could follow it with a Pentode, which I suspect would sound quite lovely. So to answer your question...there is no additional saturation circuitry. The circuit would respond to increased input gain the same way a real Pultec would, minus the transformers of course. The DOA will give you the characteristic grit, punch, and presence you expect from a 2520-flavored op amp as you drive it harder. I chose to load the DOA as if it was driving a transformer so it will have some coloration. gouge - Yes, this new module would pair up especially well with the new CP5 preamp Peterson put out. That's kind of why I chose to release this one now. Of the few ideas I've been developing I felt this one would be the best complement. Brad |

I sent you an email about it?  |

Oh cool! I didn't know you had Pulse. I don't recall getting your email. Feel free to email or text me.

You guys have any suggestions for sound clips you'd like to hear? Anyone want to provide some mix or drum buss clips?  Brad |

Brad you just keep coming up with cool ideas and bring them to market !
You my man are one of the contenders for my " I want what he's smoking " award!

Thanks, Eric! You just totally made my day. I just create the things I want. I think I have a brain that needs to be designing/creating something 24/7 or else I feel like I'm being idle and useless. My friends tell me I need more vacations and relaxation.  Plus I kind of see the Colour format as an outlet for me to make an artistic statement of sorts--in a punk rock kind of way I get satisfaction giving classic (expensive) pieces of gear the finger as I miniaturize them and sell them to fellow mortals for $129.  By the way...it just hit me that if you add additional jumpers to the frequency header you can achieve in-between frequencies and frequencies lower than 3k. Pretty cool! Brad |
