Marshall2555X Silver Jubilee 100W Tube Guitar Head

Independent shopping perspective
The Korena take
Marshall’s 2555X is a 100W tube head that brings the original 2555 panel feature set into current production. Pentode/Triode switching gives you a full-power setting and a setting that halves the output. At the back, five speaker outputs span 16 ohms through 4 ohms, replacing the original model’s impedance selector. External chassis bias points also make re-valving and servicing more direct. Each amplifier is built for the mains voltage of its destination country.
Strong match
Who this is for
- Guitar rigs needing a 100W tube head with a switchable half-power operating mode.
- Setups that require speaker connections from 16 ohms down to 4 ohms.
- Players who value accessible external bias points for re-valving and servicing.
Consider the trade-offs
When to look elsewhere
- Use in a country with a different mains voltage than the amplifier’s fixed country-matched configuration.
