Great module, but lack of a build guide messed me up.Review by Dash508
This module sounds fantastic, sadly though, only one channel is currently working on mine. (A proper build guide would have been quite helpful).

Due to the lack of a proper build guide, I was able to successfully solder everything in place except for the LEDs which had no indication of polarity. (Only marking on the PCB was a single white dot, which as it turns out wasn't very helpful.)

After soldering everything and plugging it in, both channels worked beautifully, however, the LEDs did not light up.

In the process of attempting to remove the LEDs and invert them, I accidentally removed on of the resistor pads, destroying the upper channel.

If I had been givin some indication of the placement of the LEDs beforehand, I would have a perfect working module right now.

I will say again, the one working channel sounds and functions absolutely amazingly for the price and hp.

(If anyone else attempts this build, the cathode goes with the white dot) (Posted on 3/19/2017)
vactrol goodness!Review by rocketshipajax
Amazing Low Pass Gate module with sweet Vactrol character in only 2 HP! Can't be beat on price, size, or functionality of modules in it's class. Oh, AND it's Passive! (Posted on 8/17/2016)
