[Harp-L] Blues Jr. Upgrade Kit

[Craig (Skip) Effress <effress@xxxxxxxxxx>]

Hello All....Has anyone tried the Fender Blues Jr. Upgrade Kit that 
Harp Depot sells for $29.95?   The kit consists of 3 replacement tubes 
(one ECC81, one ECC832 and one ECC835S).......I'm thinking of getting 
it, but I'd first like to hear from anyone who has tried it and can 
comment on what the kit will do to make the Blues Jr. more harp 
friendly.....I'm looking for a more "crunchy", "dirty" tone from my 
amp.....Thanks very much for your help.....Skip
