Product Description


Read about the Juggernaut Preamp from Grammy award winning Producer/Mixer/Bassist John Spiker:


The Juggernaut Twin is a two channel 1RU (19" outboard rack unit) class A discrete, transformer switchable, impedance selectable microphone preamp. The Juggernaut Twin is an expanded version of the Juggernaut 500 preamp (please see all the basic details of the Juggernaut 500). If you are already familiar with the Juggernaut 500 read on, if not please take a moment to read about the Juggernaut 500 which has more details about the standard functions and tonal options that we have built upon to create the Juggernaut Twin.

The Juggernaut Twin is the ultimate in microphone preamps, the king of flexibility, the sultan of tone. It's the preamp you have been searching for your entire life, it IS just THAT awesome. It has even more features than it's brother, the Juggernaut 500. The new added features have opened up even more possibilities for today's modern engineer. It is THE DESERT ISLAND PREAMP. We've provided more sonic choices than any other preamp on the market. The larger 1RU rack has allowed us to expand upon the design philosophy we established in the Juggernaut 500, which is versatility versatility versatility. With more physical space in the 19" outboard unit compared to the 500 series card format, it allowed us to give the end user more options. No longer will you need multiple preamps in order to get the right sounds for your recordings; you only need one, the only one that can give you the tones and textures of many....the Juggernaut.

What is the difference between the Juggernaut 500 and the Juggernaut Twin?

The Juggernaut Twin has all the style and flavor as the original Juggernaut 500 preamp plus these cool new additions...

Output transformers can now be switched via pushbutton on the front panel, allowing the user to access all 4 transformer combinations by simply pushing the input and output transformer buttons of your choice.

We have added dual outputs on balanced XLRs on the back of the Juggernaut Twin, something that can be very useful when recording in the studio or on location. We have also added +4 dbu line level inputs on XLRs, to send in your line level signals to fatten up or color your synths, stereo mixes, or individual tracks.

We've added a FAT switch which uses passive inductors/chokes; this gives you the ability to mellow out the high-mids and gently lift the low end to give that extra low end emphasis on key sources like drums, bass, vocals, etc.

And finally, we have provided the ability use the iron or nickel input transformer in the instrument DI path, you can still choose transformerless DI as well, this is selectable using the new Line to Mic switch via pushbutton on the front panel.

All of these new pushbutton features are incorporated into an intelligent and intuitive interface on the front panel.


Excerpt From TapeOp Magazine Review

"I'm not going to be at all coy about this. I won't pretend to be neutral as I describe the Juggernaut Twin mic preamp. I am smitten. After months of owning it, I find myself still reaching for it and discovering new sounds. I've developed a few favorites, but this thing is an all-you-can-eat sonic buffet. This two-channel unit will never leave my rack.


The Juggernaut Twin is just an incredibly versatile mic preamp that offers anything from huge, transparent sounds (think Crane Song Flamingo) to darker, smooth sounds (Neve). This box delivers the goods over and over. I continue to reach for it first in most applications, and I'm waiting for the novelty to wear off, but I think it's going to be a long wait." - Jim Chapdelaine
