zZounds Gear Experts Say...
Originally used in early Vox amps, these Groove Tubes have regained popularity as a result of its subtle overdrive distortion.
Overview
These tubes are good quality, long lasting type with a slightly aggressive edge when pushed into overdrive.
EL84 Type (typical power ranges from 5 to 8 watts)
These are the most common low-power pentode, popularized in early Vox AC30 amps. They were rediscovered by Matchless amps and now currently used by nearly every tube amp company. They produce a quick, soft overdrive distortion, great for recording but usually too low volume for live gigs.
