Caline: CP-60 Wine Cellar Technical Review & Teardown

@Jo Bass Thank you for demoing this pedal! This pedal was given to me by Caline Technologies as a thank you for helping out with the CP-81 voltage/noise issue. This is my review of the pedal. This pedal is actually an awesome, inexpensive, & useful preamp DI pedal! There is an RC4580 op amp driving the XLR, a 4558 op amp driving the 1/4“ buffer circuit, and the drive circuitry is two TI074C quad op amp chips. All very good quality parts!! This is not a true bypass pedal, contrary to what the website says. You need 9 volts powering the pedal in order to pass any signal through, even if the pedal is disengaged. The 4558 op amp runs the buffered 1/4“ in/out, and the footswitch bypasses that circuit from the drive circuitry. It’s not a big deal, but in the traditional definition of “true bypass“ this pedal is not. The XLR is a genuine electronically balanced DI output. There is no ground lift switch becau
