to Benefit Chicago's Haymarket Recovery Center

NORTHFIELD, IL, October 11, 2016 - Schroeder Amplification today announced its role as a key organizer and supporter of the upcoming benefit auction for Haymarket Center, a recovery facility in Chicago, IL. The seven-day online auction will begin on October 17th, 2016 and will be hosted on, the online marketplace for buying and selling musical instruments and gear.

Schroeder will donate the first two prototypes of the as-yet-unreleased Jeff Tweedy (Wilco) Ramjet Preamp, a dedicated high-end guitar preamp designed to deliver a wide range of clean to overdriven tones in the studio or on stage.

The mission of Haymarket Center is to aid people with chemical dependency in their recovery by providing professional care. Founded in 1975, Haymarket is the largest not-for-profit community-based adult detoxification, residential and outpatient substance abuse treatment facility in Chicago.

"For many years I've wanted to do more to help better the lives of those struggling to overcome alcohol and drug abuse," said Tim Schroeder, president of Schroeder Amplification. "I'm proud that this dream is finally going to become a reality thanks to the help of Haymarket Center, and the participation of Jeff Tweedy."

Tweedy added, "Tim's gear has been a constant for Wilco on stage and in the studio for years, and this new preamp is a fun and useful recording tool. I'm very happy to be a part of this effort to help the auction raise money for such a good cause."

The Jeff Tweedy Ramjet Preamp is designed to provide some of the guitar tones that Tweedy used throughout Wilco's Star Wars album, achieved in part by overdriving the recording studio's mixing console. The Ramjet (street price around $2,000) embodies Schroeder's design philosophy of combining traditional guitar amplifier circuit design with audiophile-grade internal parts usually found only in high-end audio components. This enables the Ramjet to deliver wide frequency response and dynamic range and go from pristine clarity to richly saturated, harmonically complex overdrive and massive distortion. The two Ramjet Preamps will be signed by Jeff Tweedy and Tim Schroeder. For more details on the preamp please visit

"At, we live to help musicians find that perfect piece of gear to make their music. We're thrilled that this auction will give music lovers the chance to get their hands on a unique, new preamp while also benefiting a great cause," said David Kalt, CEO and Founder of

"As the largest residential drug and alcohol treatment provider in Chicago, serving over 16,000 men and women each year, we continue to be strained in our providing services that are in need more now than ever," said Ray Soucek, CEO of Haymarket Center. "Due to the State of Illinois not funding these services at the level of need, we are so grateful for Tim Schroeder's help and support. Having someone show generosity in this way not only helps raise resources, but also brings attention to the need."

The auction will begin on Monday, October 17th at 12:00 pm Eastern Standard Time and end on Sunday, October 22 at 12:00 pm EST. In addition to the two Schroeder/Jeff Tweedy preamps, other auction items will include a pair of Audience ClairAudient 1+1-V2+ high-end loudspeakers, a vintage VOX AC50 Mk III amplifier and assorted vintage guitars. All items will be offered with a starting bid of $1.00 and no reserve. The auction will be open to bidders in both the U.S. and internationally. Payment will be accepted via PayPal, etc. The Schroeder/Tweedy Ramjet Preamps will be accompanied by a Certificate of Authenticity.

Key Jeff Tweedy Preamp Features and Specifications

The Ramjet Preamp is a culmination of 14 years of design. What makes the Tweedy Ramjet version different than the standard Ramjet is that its controls and functionality have been streamlined for the specific tones Jeff favored when getting to know the first prototype. He wanted to be able to "dial in" those sounds without twiddling the multiple knobs and switches found on the original version. These tones just happen to be the same sounds which can be heard on Wilco's Star Wars album: that ridiculously cool overdriven Neve channel sound!

Tube Complement:

(2) 12AX7, (1) 6V6. Each tube has been selected by ear for its individual position in each prototype.

Front Panel (left to right):

- Standby switch

About Schroeder Amplification

Schroeder Amplification was founded by Tim Schroeder as a natural evolution of his decades of experience as a master luthier and amplifier technician. Tim trained as a luthier and audio technician before opening Schroeder Guitar Repair in 1991. During this time he began development of amplifiers to complement the guitars and ultimately founded Schroeder Amplification, currently located in Northfield, Illinois.

Schroeder's "guitar amplifier meets high-end audio" approach makes it the only company to extensively use audiophile-grade internal components in guitar amplifiers. Usually found only in high-end audio products, the use of such audiophile parts is evident in Schroeder amplifiers' full frequency response, exceptional touch sensitivity and ability to go from crystalline clarity to richly saturated, harmonically complex overdrive. Schroeder's growing artist roster includes Jeff Tweedy, Nels Cline and John Stirratt (Wilco), Jake Cinninger (Umphrey's McGee), Andrew Bird, Rusted Root and Modest Mouse to name a few.
