GROOVE TUBES GLORY COMP ALL-TUBE COMPRESSORREADY TO SHIP TO GT DEALERSANAHEIM, CA (January 20, 2005) – Announced last year, Groove Tubes’ Glory CompAll Tube Variable Transconductance Compressor has gone through rigorous testing in avariety of professional applications, and will soon begin to ship to the company’s dealers
and international distributors.
“Engineers who liked our ViPRE will love the Glory because it’s just what they havebeen asking for: a no compromise, transparent, rich all tube compressor with virtually no
trade-off in frequency response loss even in the most compressed settings,” says
Aspen Pittman, Groove Tubes founder and president. “In addition to its incredible soniccharacter, Glory Comp offers features that have never been found on compressors at
any price. The studios using it, including that of legendary engineer Greg Ladanyi, feelthat it’s one of the best ddddynamics processors ever made. We wholeheartedly agree!”
Employing seven high quality, hand selected Groove Tubes to drive a custom-wound
output transformer, the Glory Comp makes use of variable transconductance tubes fortheir superbly linear modulation of the input signal. Known for their smooth response toprogram material, variable transconductance tubes have been employed in some of themost revered vintage compressor/limiters such as the Fairchild 670.

Page 2Glory Comp's fully differential and floating design includes dual isolated output taps onits proprietary output transformer so it can interface with both -10dBV and +4dBu signal
levels without sacrificing signal quality or degrading noise specs. Compression ratiosfrom 1:1 to 6:1 are available, as are standard Attack, Release and compression
Threshold controls. In addition to release times from 25ms (linear release mode) to 2
seconds, users can choose between logarithmic and linear release modes. Like theViPRE, the Glory Comp implements several high-quality ceramic multi-decked switches(instead of less expensive potentiometers), for maintaining the balanced signal path andalso for allowing for easily repeatable settings. Also like the ViPRE, the Glory Comp
provides a custom-built, backlit VU meter that can display in nine different modes.
The Glory Comp also features a built-in sidechain EQ with adjustable low and highfrequency filters, along with an internal or external sidechain source selector.
Completely unique to the Glory Comp is the Glory knob, which adds low-order evenharmonics to the compressed signal. The Glory Knob has several creative applications(like adding perceived fullness to a bass without increasing signal level, or similarly
bringing out a vocal or a solo instrument in a mix). The Glory Knob's labeling allows
adjustment between Earth (no effect) and Heaven (full effect).
The Glory Comp will soon be available through Groove Tubes Pro Audio retailers, with asuggested retail price of $3,499 (USD).
