MarshallJTM45 30W Tube Guitar Amp Head
1/6
Independent shopping perspective
The Korena take
30-watt reissue of Marshall's first amp, built around 5881 power tubes and ECC83 preamp tubes. For players chasing early Marshall breakup rather than modern gain.
Strong match
Who this is for
- Blues and classic rock players who drive the amp with guitar volume
- Studio use where 30 watts breaks up at usable volume
- Pedal platform for players who prefer dirt from stompboxes
Consider the trade-offs
When to look elsewhere
- Modern metal players — no high-gain channel here
- Anyone needing channel switching; this is a single-voice amp
- Players wanting clean headroom at loud stage volumes
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
30 watts
Reaches power-tube saturation at volumes a small club or studio can handle, unlike a 100-watt head.
Detail 03
3 x ECC83 preamp tubes
The classic Marshall preamp complement. Gain builds gradually rather than slamming into distortion.
Detail 04
32 lbs
Light enough for a one-hand carry to the car, unusual for a tube head.
Detail 05
26" x 10-1/4" x 8"
Standard head footprint. Sits on any typical 4x12 or 2x12 cabinet without overhang.
Final check
Know before you order
- 01Head only — cabinet and speaker cable are separate purchases
- 02Always connect a speaker cab before powering up a tube head
- 03At 30 watts, good tone means real volume; a bedroom setup will fight you
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Is 30 watts loud enough for a band?
For most clubs, yes, mic'd or on its own. It will break up sooner than a 100-watt head, which is the point of this amp.
02Can I get metal tones from it?
Not on its own. This is early Marshall breakup, not modern high gain. You would need an overdrive or distortion pedal in front.
03What do the 5881 tubes change?
5881s break up earlier and sound rounder than EL34s, giving the amp its softer, more vintage character at lower volumes.
04Does it have an effects loop?
This is a vintage-style circuit, so plan on running time-based effects into the front end unless the rear panel says otherwise.
