THE Preamp Tube for Getting the Front End of British Tone!

Note: all of the Groove Tubes tubes and sets we carry are "Mediums," or in the 4 to 7 range.

Groove Tubes has been manufacturing, importing, and grading quality power tubes for two decades. No stranger to Sweetwater, Groove Tubes founder and energy source Aspen Pittman has paid us numerous informative (and always entertaining) visits through the years. His tireless pursuit of perfect tube tone has resulted in Groove Tubes' reputation for consistency and premium quality. Want proof? Fender tube amps now include Groove Tubes as standard equipment, and true tube aficianados worldwide swear by the tubes and pro audio products Groove Tubes makes. For premium tube tone, choose Groove Tubes!

The GT-ECC83S preamp tube represents the classic "Euro" type tube, with medium to high gain and a linear frequency response. The GT-ECC83S gives you a very clear, even tone with good bass character. This tube type was long used as standard equipment in Marshall and Vox amplifiers. For those who change first stage gain preamp tubes to change the character of their amps (remember, this can be done in less than a minute without tools, adjustments, or a "tech"), the GT-ECC83S is definitely an essential.

Sounds great

I tried this in my Le Bass pedal. This tube has a different sound than the original that came with the pedal. I like this one better. Good stuff!

Groove Tubes GT-ECC83S

Replaced the preamp tubes in my Peavey Classic 30 from 12AX7's to Groove tube ECC83S's and what a nice change. The Peavey tubes are not junk by any means. They were Electro-Harmonix in my amp and were fine but my amp needed just a bit of tweaking. Only takes 3 tubes and no tech work since I didn't change the power tubes. A nice way to dial your amp in for just a few bucks.

Tubes make a difference

Bought 2 of these. Replaced a Chinese tub in a mic pre and and an MX 2000 effects unit and sound quality improved in both dramatically. Easily noticeable.

Quality tone

I installed as an upgrade to MIC Amps. Can't go wrong with these. Not too proud or thin. Just good tonal presence.
