i tired the KT77s in many amps. LOVE EM!! im not a huge EL34 fan ( i like some) but the 77s just rocked. Good in betweener of the EL34 & 6L6. Nice bottom end. great clarity. nice cleans. I know i had 34s in my VH4 & just swapped em or yucks..and it brought the amp to life!! In my Splawn..just killer!!
i just recently put a quad in a friends Orange Rockerverb. WOW!!! Lethal!! But still maintains that "classic" sound
The Gold Lions are a much better made tube than the JJs. i know alot of people had issues with the JJs failing. But what tubes dont fail these days!!
