Groove Tubes GT-EL84-S Duet (Grade 8, matched pair)
New European version with even more response, higher power and warmer tone.
Most common low power pentode, popularized in early Vox AC30 amps. Rediscovered by Matchless amps and now currently used by nearly every tube amp company. Quick, soft overdrive distortion, great for recording but usually too low volume for live gigs
