Passive Pultec Air Boost
for Chroma, Mister Focus, & DIYRE Colour



There just may not be anything more gorgeous than strapping a pair of Pultec EQP-1A3 equalizers across a mix and boosting 12 or 16 kHz to add some top end galactic fairie dust. The sonic architects at Rogue Planet Command have commissioned Louder Than Liftoff to issue a high frequency boost for the Colour format faithfully based on this legendary passive EQ. Our unique incarnation is inspired by two variants of the famed vintage unit. In the late 1970's Pulse Techniques, Inc. debuted a solid state version of the famed EQP-1A3 that featured an API 2520 discrete op amp to provide make-up gain for the passive EQ network instead of the usual tube amplifier. There was also a rare version (EQP-1S3) that offered 5 and 10 kHz high frequency shelving settings. We created a hybrid of the two and integrated an expanded set of passive shelving filters with a 2520-powered make-up gain amp to yield a combination that pulls high frequencies effortlessly to the front of any track or mix. To ensure maximum tonal bliss, Rogue-Tec Air is offered with the same ROGUE FIVE‹¢ discrete op amp we spent the last two years fine-tuning for the Silver Bullet.

About Colour

Colour is an exciting new modular platform for creating your own custom analog signal chains. The ever-growing family of modules allows you to bring multiple stages of high end analog processing to your setup a la carte.

The Colour platform consists of Colours and Palettes. Colours are ultra-compact, swappable analog circuit blocks that snap into the Palette, and impart various types of analog color such as distortion, saturation, compression, and even echo. The Palette provides input and output controls, power, and support circuitry for up to three Colour modules.

Currently, the Palette is available as a 500 Series unit from DIY Recording Equipment. In the near future there will be rackmount and Eurorack versions of the Colour Palette as well.

Policies & FAQ

14-day No Hassle Return Policy

Try out our gear in your studio and, if within 14 days you're not satisfied, let us know and we'll issue a refund.

To be eligible for a return, your item must be "like new" and in the same condition that you received it. It must also be in the original packaging with all original materials (power supply, power cord, product card, etc.).  Please refrain from racking 19 inch rackmount gear during this trial period so that the faceplate and enclosure don't get scratched.

To complete your return, just give us a call or shoot us an email, and we'll send you instructions for packing up your unit and shipping it back.  Please note that you will be responsible for return shipping costs and we ask that you insure the unit for its full retail value to protect against loss or damage.  You are responsible for ensuring the products arrive safely at our shop.  Once we receive and inspect the unit we will issue a refund for the purchase price less the cost of shipping.  Units received in any condition other than "like new" may be subject to a restocking fee.

World-Class Shipping

We ship to (just about) any address in the world via USPS, UPS, FedEx, and DHL Express. When you place an order, we will estimate shipping delivery times for you based on your location and the shipping option you choose.  Delivery time estimates are given on the checkout page.  Once payment is approved, in stock products, other than Silver Bullets will ship out from Rogue Planet Command within 2-3 business days.  We ship Silver Bullets within 7-10 business days.  Once an order ships you will be sent tracking information via email and/or Facebook Messenger (if selected at checkout).  Please coordinate with the shipping company to have your package held for pickup if you know you will not be home when the package is expected to arrive.

Please note that the shipping rates for many items we sell are dimensional weight-based. To reflect the policies of the shipping companies we use, weights may be rounded up to the next full pound.  We may substitute UPS for FedEx ground service and vice versaWe also may upgrade UPS and FedEx ground service to USPS Priority Mail if we are feeling extra nice.  

Also note that international customers are required to pay all import duties and taxes required by their respective countries.  When filling out customs forms we declare the actual purchase price.  Please do not ask us to declare lower values.

If you reside outside of North America, we highly recommend DHL Express when ordering a Silver Bullet for the quickest delivery and with zero customs headaches.  If you are in Canada we recommend selecting USPS instead of FedEx or UPS since the customs process is easier and less money.

We require a signature for all Silver Bullet orders to help ensure you safely receive the package.

When can I expect to receive a response to my email or phone call?

Most emails or phone calls will receive a friendly reply within 24 hours, and often within just a few hours.  However, sometimes we get sucked into the glorious nebula of designing and building products.  Or need to do laundry, shop for groceries, or sleep.  We appreciate your patience as we balance the demands of our intergalactic commitments, and try to enjoy time off on the weekends.  Please don't be upset if an email you sent on Friday evening doesn't get returned until Monday or Tuesday morning.

Do you have Silver Bullets in stock?

Please check the FAQ tab on the Silver Bullet product pages for up-to-date information about stock, production status, and shipping dates.

How much will it cost to ship my order overseas?

Our shopping cart has a shipping calculator that is configured to estimate shipping to anywhere in the world.  All you have to do is add a product to the cart and then click the cart icon in the upper right corner of your browser.  At that point you can select your country, province, and enter your postal code.  A list of available shipping options will be displayed after you click Calculate Shipping.  As mentioned above, international customers are responsible for paying all import duties and taxes for their respective countries.

What shipping option do you recommend for European customers?

If you are ordering a Silver Bullet or 500 series module, we highly recommend that you select DHL Express shipping.  DHL acts as the customs broker and offers exceptionally quick door-to-door service.  We've been seeing packages arrive in the UK in 4-5 days.  There is no hand off with local postal services like there is with USPS so you will know where your package is every minute of the day by accessing the tracking information. They will require you to pay all customs and import taxes before delivering the package to your door.

My country charges high import taxes.  Can you adjust the customs value to help me out?

Sorry, but no.  As a rule, we declare the actual purchase price on all customs forms.  Defrauding a foreign government is not a wise business move.

Do you accept wire transfers, ACH payments, or Paypal as forms of payment?

We only accept payment through our online store using major credit and debit cards at this time.

How are you guys able to sell products of this quality level at these impossibly affordable prices?

We simply reject the notion that a middleman like a dealer or distributor needs to come between the guy that designs and builds the gear and the artist that uses it.  By adopting a direct sales model we have been able to pass that savings onto our customers.  Do you really want to pay 30% more for your gear?  All we ask in return is that you make lots of great music and help spread the word about our company and products.

Can I have my favorite pro audio dealer get me a Silver Bullet?

Sure, if you want to pay more money for our products.  See the question above.  Our pricing model does not allow for typical dealer margins.  Really.  If you'd like to order 10 Silver Bullets we'd be happy to give you a sweet discount though.

I just bought a used unit from some dude online.  Can I have the seller send it to you first to check out?

As a policy, we decline to get in the middle of third party transactions on used gear.  If you receive the unit and it requires repair please contact us and we can go over service options.
