Fender GT-6550-R DUETS (RATED 1-10)

BIG TUBE BASS AMP TONE One of the highest-output 8-pin pentodes available. Originally manufactured in the United States by G.E.®, it delivers 35 to 50 watts per tube and was original equipment in amps during the ’70s and early ’80s. A big, clean, tight tube with amazing headroom and performance and great power and dynamics. The highest-output power tube in this family. This 6550 is slightly easier to push into distortion than the original G.E. version and has a harder response than the «C» for tighter, quicker response. Good for bass amps and metal, when more pronounced note definition is desired with just a touch of distortion.
