"Fabulous Fred Mod" on any Groove Tubes manufactured Brick, to be performed by APD, Aspen Pittman Designs company's in house service department. Our turn around time is usually one day from receipt of your Brick. "Fabulous Fred Mod" was an official Groove Tubes ECN (Engineering Change Notice) that was scheduled for the next run of GT Bricks. However it was never implemented to any production run of Bricks because Fender bought GT and discontinued all the GT audio products back in 2008.

So, if you have a Brick, it is certain that you will NOT have the. "Fabulous Fred Mod" (although we have performed this mod for a few high profile local friends in the LA area). Ffm mod increases system gain by 10+dB and extends the frequency range at both ends of the scale...

Fans included the top names in the industry including legendary bassist Leland Sklar, pictured here with his "great tasting" GT Brick! "Fabulous Fred Mod" only makes it better, noticeably better! The Story behind the Fred Mod. Aspen Pittman, the owner/founder of GT, told his GT engineers to "go play" in the engineering department and come up with some factory upgrades where ever possible.

As the Brick was one product Fender indicated they would continue (but didn't), hat was a prime target for upgrade. One of the GT engineers, Fred Bova formerly with A&M studios, came up with a fabulous mod for the very popular GT Brick that corrected some original design flaws. Aspen really loved what it did for our Brick, so we named it the. Following a year of chemotherapy and with his health restored, Aspen began building his unique 32 channel all tube based live large format recording studio in the original GT factory building which he still owned, and he still uses these Brick.

Ffm preamps daily at his APR (Aspens Place Recording) studios. Aspen still maintains a lab there in this building located in San Fernando (2.2 square miles of heaven surrounded by Los Angeles), and also continues to design and develop new products for himself and other clients. Your Brick will be upgraded at Aspen's own lab... A few years ago, Aspen launched a new company, APD; Aspen Pittman Designs. These new APD line include: Aspen's patented Center Point Stereo Spacestation v. 3, a stereo powered monitor that produces a 3D stereo image everywhere in the room; a new version of his TEC award winning GT Convertible condenser mic for stage and studio, the Dual Top One (DT1) with a removable ball top for use as either a vocal or instrument mic; a unique magnetically attaching steel mesh pop filter, the PFM; and also Aspen most recently released a dual tube, dual OD pedal for guitar called the Duo-Tonic. There is an extensive archive of GT product catalogs, schematics and other ECN for these products on the Aspen & Associates website.

Ffm upgrade thru his APD company. Ffm tube preamps have higher gain (+10dB) and extended high (and low) frequency response... And overall MUCH flatter frequency response as compared to the original Brick circuit. We also change out the gain pot to a different type. A 5K reverse audio taper pot.

Ffm Brick's gain transition is much smoother and equal you don't get 90% of the gain in the last 20% of the pot's travel. But rather, an improved equal and gradual gain change. See the attached "before and after" gain and frequency response graph from our Audio Precision computer test systems here in our APD Labs. The top RED line is the Brick. Ffm gain and frequency curve. It has near perfect flat response from 20Hz to 20+KHz, plus a +10dB gain increase over the stock Brick, shown on the lower BLUE line. Also notice the stock Brick has a noticeable (and audible) roll of at both ends of the frequency response curve, as compared to the Brick. Your Brick should be in good working order when you send it to us. Upon receipt, it will be evaluated on our Audio Precision test systems before and after, and you will get a printout of this in your return package. NOTE: if your Brick (or ANY GT audio device such as ViPRE, SuPRE, Glory COMP, etc) is not in good working order and needs repair, we highly recommend Paul Morte Technical Services in Orange California. We are not a service center, they are. And they do that job very well at reasonable prices. "Fabulous Fred Mod" is extensive and requires total disassembly. It takes about 1.5 hours to perform plus adds many new specialized parts, which are added and/or substituted. This mod also upgrades the GAIN pot to a special reverse audio tapper pot that allows a much finer gain adjustment.

So, instead of all the gain in the last 1/4 of the pot, it is even thru out the range... And it actually improves the sound a too!
