The Caline CP-49 Midlander is an overdrive pedal made by Caline, a maker known for low-priced effects1. It is a Tube Screamer-style overdrive circuit built around the RC4558 op-amp chip, the same chip family used in the Ibanez Tube Screamer line that this design follows2.
What it does
As an overdrive rather than a distortion pedal, the Midlander pushes the guitar signal into clipping that mimics a tube amp working hard, adding warmth, sustain and midrange growl rather than the heavier, more aggressive clipping of a distortion pedal. Its Tube Screamer-style design means it follows the most widely copied overdrive circuit in the pedal world, one known for a midrange hump and a tightened low end2.
The RC4558 chip at its center is the op-amp long associated with that circuit family, and its presence in the Midlander places it squarely in the classic Tube Screamer lineage rather than among the many modified or original overdrive designs on the market2.
