Guitar World Verdict

Flattley’s The Ace is good-sounding boost pedal with plenty of whomp delivered with sensible tonal options. It’s ideal for giving you that extra push and emphasis for solos but is equally adept as an always-on component, adding a buffer and boosting signal strength with enhancement for your core tone.

The latest from Flattley Guitar Pedals, the Gloucestershire, UK-based effects company, is The Ace, a clean boost/buffer with the advantage of having a Tone knob to target the boost. It features a blue halo light ring showing its engaged status and a topper on the footswitch, giving you a bit more to aim for when switching.

The Ace’s tone stack is the same as that in Flattley’s Solaris Pro fuzz and boost pedal and is designed to deliver an effectively flat sound when the knob is central, with a bass boost to the left and a treble boost to the right. The most neutral position of the Tone knob isn’t totally flat, but kicking in the pedal yields a subtle change in the midrange that seems to thicken your basic sound.
