The New Marshall JTM1

For it’s 50th anniversary Marshall is introducing a line of 1 watt tube amps inspired by some of the classic Marshall amps that we all know and love.

The first out of the gate is the Marshall Limited Edition 50th Anniversary 1960′s JTM1 Combo. This amp draws from the earliest of the Marshall line, those direct decedents of the Fender 5F6A Bassman. I’m not sure how closely the circuit emulates an original JTM45 since the JTM1 only has 2 12AX7 tubes. The original used 3, 2 for the preamp and one for the phase inverter.  The JTM1 also uses a single tone knob as opposed to the Treble/Mid/Bass tone stack and presence control found in it’s name sake.

Regardless of what the circuit looks like, what matters is the tone and getting classic Marshall tone in a 1 watt package is certainly appealing. It achieves it’s low output by using a 12AU7 for power rather than of a pair of blazing KT66s or EL34s.

Here is the Marshall product demo video.

 

Like all of the 50th Anniversary, 1 watt, all-tube heads and combos, the JTM1C is built at Marshall’s factory in Bletchley, England, with a huge amount of expertise and pride. Each and every amp is painstakingly tested the good old-fashioned way by plugging in a guitar! The low power switch on the rear panel is a neighbor friendly feature that drops the output down from 1 watt to 0.1 watt.

The combo includes a celestion 10 speaker with 8 and 16 ohm external speaker outputs.
