Even though the 1987x shares the iconic "Plexi" front and rear panels as the famous 100 Watt 1959 SLP, it has its own distinctive sonic personality. The 1987x has a more aggressive tone in contrast to the 60's 'Plexi's'. The 1987x is reminiscent of the 70s with a heady, sweet/aggressive tone.

These tonal characteristic are what define this as a respected all-valve head. Marshall has painstakingly gone through endless care and effort to ensure that the 1987x remains true to these tonal characteristics while holding eye-watering aesthetics. The only addition to this re-issue is a tonally transparents Series FX Loop.
