The Advantages & Disadvantages of the Marshall JTM 30

Here are the advantages of using the Marshall JTM 30:


  • Suitable for any playing style and musical genre.
  • Easy to transport and set up.
  • Simple and easy-to-use controls.
  • Has an affordable price.
  • Delivers consistent performance over time.

Now, here are some of the disadvantages of using the JTM 30,


  • Limited headroom: may not be loud enough for certain playing situations.

The JTM 30 is a phenomenal all-valve amplifier, but its limitations make it less suitable for players who need more volume, tone-shaping options, or a cleaner sound.


The price of a Marshall JTM 30 amplifier can vary depending on the unit’s location, retailer, and condition. The amp has since been discontinued, but on average, you can find a used JTM 30 for $500 or its replacement model, the Marshall Origin 20W, for around $600 to $800, and that’s brand new. There’s also the JTM 45 head, in which the JTM30 was inspired, but that will be a lot more expensive.

Used or vintage JTM 30 amps can be found for sale. Their prices can vary depending on their condition and rarity. 

They might be less expensive than the new ones, but it’s important to inspect and test a used amplifier before buying it.

Marshall JTM 30 alternatives

The JTM 30 is a good choice for those who prefer a clean blues tone, but it may not be suitable for everyone. Here’s a comparison with a few other amps to give you a better idea of what the JTM 30 has to offer:

Fender Blues Junior: The Fender Blues Junior is the same size as JTM 30, but it features a different tonal character with its all-tube, Fender-style circuit. The Blues Junior is well-known for its clean and articulate tone, making it an incredible option for players who prefer a clean sound.

Vox AC15: The Vox AC15 is an all-tube amplifier similar in size to the JTM 30. The AC15 is known for its British-style tone, making it an excellent alternative for players who want a classic, jangly sound.

Orange Crush 35RT: The Orange Crush 35RT is a solid-state amp that offers more volume and headroom than the Marshall JTM 30. If you want a more aggressive, heavier tone to suit your playing style, then this amplifier might be for you.

So is the Marshall JTM 30 the right amplifier for you? 

Well, it depends on your playing style and tonal preferences. 

If you want an amplifier that provides a warm tone, has simple controls, and is affordable, you should try the JTM 30. However, if you need a different tonal character, a different size or a different price point, one of these other models may be a better fit for you.


If you’re seeking that classic overdriven sound in a compact and affordable package at a reasonable price, you should definitely consider buying the Marshall JTM 30. 

Whether you’re playing in a small club, a large venue, or a studio, the JTM 30 can deliver the classic Marshall tone you need. However, the JTM 30 has its limitations. Ultimately, you can decide if this amplifier is for you if it meets your requirements, but it’s worth trying it out.
