Great tube package
Had stock preamp tubes and replaced with JJ power tubes and Mullard lower gain tubes. Sounded good but wanted more drive. Replaced Mullards with JJ and sounded fine.
After some pedal upgrades decided to retube with this premium package. Very happy I did.
Clear, clean noise free when running dry. Run a Katana boost in front and some slight noise but handles the addition gain in preamp fine. EQ is more defined and its loud.
Well worth the investment with one small complaint: the poles/legs on the preamp tubes were slightly bent requiring some delicate force to straighten. Not sure why but made them work.
