[Harp-L] Blues Jr. Tube upgrade kit

["John F. Potts" <hvyj@xxxxxxx>]

Skip,

When i had a Blues, Jr. i installed this tube upgrade kit, which is  
also available from Eurotubes,  Before I put these tubes in, the amp  
was unusable because of feedback. After I put them in, the amp  
sounded sweeter and fatter and feedback was more controllable.   
Highly recommended.  Personally, I don't set up for a dirty or  
"crunchy" tone, but the BJ is a high gain amp anyway, and feedback  
was still a concern at higher volumes.  But the tube upgrade kit  
definitely made the BJ more harp friendly.
