Caline: CP-60 Wine Cellar Bass Driver DI Pedal: Technical Review & Teardown

‪@jobass‬ Thank you for demoing this pedal!
• Caline CP-60 Wine Cell...
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 because Pin 1 is isolated from the case. The DC negative is also isolated from the case. This may explain why a switch was never part of the design. The 1/4" jacks are grounded to the case, and there is about 11 kohms resistance between DC ground and XLR pin 1. This is typical for the design.
I would say this pedal is a good clone of the Sansamp Bass Driver DI pedal, maybe not as gritty or have as many features. It is a clean preamp with plenty of flexibility in tone control for a two band EQ that boosts and cuts. It def has cabinet speaker emulation on the XLR which is a nice feature.
Bottom line, buy this pedal!!
