Verified PurchaseI have used JJ valves in many amps including Blues Juniors. I have bought from Valve Tube Guitar Amps since i first heard of them. I have never had any problems with either the valves, the service or the delivery.
Verified PurchaseA must have for any Blues Junior. Yes you can calculate and use fixed resistor values, but this little board is so quick and easy to install you dont even need to remove the main circuit board.
Verified PurchaseThese work well with my Fender Blues Junior amp. They are quiet with a smooth tone & sufficient volume.
Official dealer. Valves tested in-house. 180 day warranty.
