Case Study Effects Lastlight Transistor Based Boost & Overdrive

The Case Study Effects Lastlight Transistor Based Boost & Overdrive is a transistor based boost and overdrive pedal, housed in a pedalboard friendly 125b enclosure with top mounted jacks¹. Pedal of the Day, reviewing it in October 2025, notes that cranking the Gain takes the pedal into distorted, fizzy fuzz territory¹.

What it does

The Lastlight covers a wide gain range. Crank up the Gain and the reviewer found it moves into distorted, fizzy fuzz territory, so players after heavier textures can reach them here. The same review notes that while the pedal is capable of producing higher gain fuzz-like tones, it really shines in the low to medium gain range, which makes it a candidate for players who mostly want a touch of grit or a clean-ish boost rather than full-on distortion¹.

The Gain and EQ controls are central to the design. Pedal of the Day's verdict: the range of the Gain and the EQ "really make this a special dirt box." That combination of a smoothed-out gain sweep and a wide-ranging EQ is what the reviewer singled out as setting the Lastlight apart¹.

Enclosure and layout

Case Study Effects updated the original design's enclosure to a pedalboard friendly 125b enclosure with top mounted jacks. Top mounted jacks keep the pedal's footprint narrow on a board, since patch cables enter from above rather than from the sides¹.

Where it sits

As a boost and overdrive in one box, the Lastlight overlaps with the territory covered by boost pedals and overdrive pedals, with enough gain on tap to brush against fuzz pedals at its top settings. For players comparing options, the reviewer's point of difference is the gain knob's sweep and the EQ range rather than raw maximum gain¹.
