The 18W head is a classic British amp in a compact format.

It delivers the typical open crunch of the late sixties – direct, warm and very dynamic. With its two channels (Normal and Tremolo) it covers a lot of ground: from a clean, slightly broken-up tone to a strong tube drive. The built-in tube tremolo is part of the sound – organic, soft and very musical. As a head it pairs easily with different cabinets while staying compact and rugged.

The 18W combo with tremolo is the classic British amp in its purest form – two channels, a simple layout, a clear tone.

It sounds open and lively, responds closely to your playing and, at around 18 watts, reaches power amp saturation early. The built-in tube tremolo is soft and musical – not an effect, but part of its character. Available as a 2×12" version with more space and depth, or as a compact 1×12" for the studio or smaller stages.

The 18W TMB head is the evolved version of the classic 18W amp – with an added EQ and a little more gain on tap.

Its voice leans towards the JTM45, but at a much lower volume. It stays compact, yet sounds bigger, punchier and a bit rougher than the tremolo version. Ideal for blues and rock players looking for real tube tone at moderate volume. The amp responds directly to your pick attack, volume and pedals, and is easy to keep in the sweet spot.

The 18W TMB combo is the version of the classic 18W amp with an extended EQ and a little more gain on tap.

Its sound is inspired by the JTM45, but it stays much quieter and therefore practical for everyday use. It delivers the typical British tone – open, dynamic and with a lovely crunch. Available as a 2×12" version with a full, room-filling sound, or as a compact 1×12" for the studio and rehearsal room.

The Plexi 45 follows the circuit of the early JTM45 – to me one of the most important classic amps of all.

Its sound sits between its Fender roots and the typical British tone – warm, round and open, with that fine, musical compression when you turn it up. It responds sensitively to pick attack and volume while always staying balanced and punchy. With the right speakers you get exactly the tone that shaped so many later rock sounds.

The Plexi 45 combo is based on the classic circuit of the early "Bluesbreaker" amp – hand-wired, rugged and immediate in its tone.

It delivers an open, slightly compressed tone with a fine response and a very natural transition from clean to overdrive. The two 12″ Greenbacks provide the warm, singing sound people associate with the British blues rock of the sixties. For smaller stages the amp is also available as a 1×12″ version.

The Plexi 80 is the big version of the classic JTM45 circuit – with four KT66s, around 80 watts and plenty more headroom.

It keeps the open, smooth character of the original, but responds tighter and with more authority in the low end. The tone stays dynamic, clear and warm – with that supple response that shaped the late-sixties sound of so many British bands. An amp for everyone looking for the Bluesbreaker sound at full stage size.

The Plexi 50 is the classic British rock amp in a manageable format – based on the circuit of the early Super Lead 50.

Two EL34s deliver enough power for any stage while staying easy to control. It responds directly to pick attack and the volume knob, and sounds open, rough and alive when you turn it up. The amp works beautifully with pedals – especially boosters and overdrives. To me one of the most versatile classic Marshalls when it comes to character and dynamics.

The Plexi 50 Master Volume is inspired by the British amps of the early eighties – more gain, more control, without losing the classic character.

Thanks to its cascaded preamp it delivers punchy overdrive sounds without having to push the power amp. The master volume gives you good control over volume and distortion, while the core character stays open and defined. A classic eighties sound – honest, powerful and precise.

The Plexi 100 is the big classic – based on the Super Lead 100 of the late sixties, with four EL34s and the sound that shaped generations.

Open, raw and direct: turn this amp up and you get exactly that feel – dynamic, biting and with long sustain. The tone always stays musical and responds sensitively to pick attack and volume. Many people associate this sound with Hendrix – and not without reason.

The Plexi 100 Master Volume takes its cue from the British amps of the early eighties – with extended gain and a flexible master volume.

Four EL34s provide the typical punch and openness of the classic Super Lead, but with more preamp gain in reserve and a stronger low end. The amp stays full and dynamic even at lower volumes. In the low input it delivers clear, three-dimensional cleans, and with boosters it responds immediately and musically.
