USA Groove Tubes

AMERICAN MADE, worldwide played! Manufactured in the U.S.A.

with the highest quality materials, of which 70% are American

components, these are an exact reproduction of original U.S.-

built tubes. Because of that, you’ll get the same stunning results

you would expect from Fender

and Groove Tubes. Once again,

they come with the same red, white, and blue color coding for

simpliﬁed replacement without re-biasing and are matched for

improved harmonic balance; longer lifespan; equalized gain to

distortion ratios; and a wider frequency response!

Groove Tubes Substitube

This completely revolutionary Groove Tubes design lets you

convert any ampliﬁer powered by 6L6 tubes into a low wattage

EL84 powered scary-nasty-monster-hiding-under-your-bed-type-

beast by dropping your output power by a whopping 70% and

leaving you with the opportunity to really crank it up! Just plug an

EL84 into the Substitube and then replace the original 6L6 with

the Substitube/EL84 concoction! Presto! You’re ready to frighten

your neighbors! Of course, it also means you can play quietly at

2a.m. and still rock, but why would you want to do that?

Classic, high-quality tubes at a great price! Fender tubes come

available as singles, matched and balanced pairs, and matched

and balanced quads to ensure you’re provided with optimal tonal

performance and lifespan!

Groove Tubes

RED, WHITE & BLUE! You chose your groove! These are the very

tubes that come as standard equipment on every Fender ampliﬁer

that leaves the factory! Groove Tubes matched sets are much

easier to replace due to the color coding system, which eliminates

the need to re-bias your ampliﬁer at every tube change. Just match

your color and then pull out the old and plug in the new! As you

increase your ampliﬁer’s volume, Red tubes stay cleaner longer,

and blue tubes begin to break up sooner. The white tubes are your

middle of the road! Groove Tubes feature an improved harmonic

balance; longer lifespan; matched gain to distortion ratio; and a

wider frequency response!
