hi,new here, 1st like to thank Myles for this forum. i have gt solo 75 I've been using for the past 6 /7years . i've Been useing svetlana 6L6 & have never changed preamp tubes, stock groove tubes.i just sent for the bias kit & wondering if you have any tips for me about this amp.the only time it was biased was when i went to the svetlana from the gt's6l6 that came with the amp.i just thought i'd add it' a 1-12 combo & my playin style is mainly blues & R&b.
Thanx's nick
