The Mesa Boogie Studio 22+ amplifier uses 4 x ECC83 preamp valves (also called 12AX7), 1 x Balanced ECC83 for the phase inverter and 2 x EL84 matched power valves/power tubes.
Note: The original Studio 22 also uses the exact same set.
Over time your valves will lose their tone and their power. A brand new set of valves will get your amp sounding like new again. We always recommend JJ valves for the Mesa Boogie Studio 22+ amplifier. This is because they guarantee you get awesome tone and long life and they don’t cost a fortune.
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.
So restore the tone, the power and the sparkle to your guitar amplifier. Treat yourself to a brand new set of valves today.
If you have any queries about replacing your valves please get in touch. We have over 30 years experience so one of our team will always be happy to help and advise.
We also recommend that you take a look at our FAQ section before you contact us. Here we answer all the most popular questions we get asked each week. We also give you lots of useful tips if you have not changed your valves before.
The reason we don’t sell Mesa tubes is that Mesa doesn’t make amplifier tubes. They simply buy them from the main five manufacturers, of which JJ is one, and then rebrand them. We think they are overpriced.
However, what Mesa do promise is their valves are perfectly matched and biased for this amp so you don’t have to rebias the amp. That’s great – and we guarantee that too, but without the hefty markup because we buy directly from the valve manufacturer.
