JJ valves a renowned around the world for their sound quality. They produce a smooth clear high end with a clean and clear treble. The midrange is full and well balanced with a tight and well defined bass end. The JJ produces a warm overdrive with a little compression and no harshness.

The JJ 6550 has proved an excellent valve for all applications. In my Marshall VBA400 bass amplifier the JJ 6550 has provided me with consistent and reliable performance. The JJ 6550 has a very lively punchy sound which will recreate all the modern bass sounds and also works very well on 5 string bass due to its excellent bass clarity. The low end bass response is very tight with plenty of depth and lots of clarity. So this valve will produce all the vintage rock bass sounds with ease. The JJ is also very well constructed with large anode plates and thick grade glass. The Marshall puts out a lot of low end and these 6550 did not show any mechanical rattles after extensive gigging, so can be fully recommended.

The set consists of 12 valves

3 Specially Selected ECC83S JJ for V1, V2, & V4
