Marshall JMD1 100 Watt Head

Marshall JMD:1 100w

Looking for great sounding valves for your Marshall amplifier? You’ve come to the right place. 

Best valves for the Marshall JMD:1 100w head.

The Marshall JMD:1 100w amplifier uses 2 x ECC83 (also called 12AX7) preamp valves and 4 x EL34 matched power valves/power tubes.

Over time your valves will lose their tone and their power. A brand new set of valves will get your amp sounding better than ever.

We always recommend JJ valves for this amplifier. This is because they guarantee you get awesome tone and long life – and they don’t cost a fortune. We also sell original Marshall El34 valves for those owners who specifically want the Marshall brand.

Remember, JJ is one of only five manufacturers of valves in the world. So don’t pay higher prices for valves from the same factory that have simply been rebranded by other companies.

Order your valves below and hear the difference.
