I'm bumping this thread to give a bit of feedback on the MegaBeat Audio "Darth Fader" pedal. It arrived yesterday and it's great, exactly what i needed, and lovely and simple to use.
You just set the fade mode from the 3 options in, out, or "in out" (this last one alternates between in and out each time you press the pedal), set the duration in seconds from 1-40, and set the depth of the fade, which is how many decibels of the volume you want to fade down or up by, up to a full 60db maximum. If you turn the knob up all the way it fades all the way, half way and it fades half way, etc.
It's also got 3 preset slots and very good large sized LED indicators which are easy to read at a glance.
It has true bypass, and works on 9V battery or any standard connection centre negative PSU with the right power rating. I'm using it with my Boss pedals PSA-240 power supply and daisy chain cable and it's working great.
The build quality is very good. The external switches and connectors all look like good quality, tough, and hard-wearing components. The first thing i did when i got it was to crack it open and take a look while removing the included battery. It's hand made, and hand made WELL with good wiring and connections, and a fairly rugged looking PCB. I was particularly impressed by the warranty offered. It has two years all parts and labour and free shipping included, which shows they have a lot of confidence in the quality of their pedals, and they seem to offer a very personal level of customer service. They even threw in a free daisy chain cable because the order was delayed by a few days while they waited for some parts to come in, which was a very nice touch.
It cost me €169 including shipping. That was an introductory price, down from it's usual €199 price point. It's a little expensive, but it's basically a hand built non mass-produced pedal which should last me a lifetime, and looks like it comes with really good quality customer service to boot, so i can't really complain, as it looks like it offers very good value for the money.
Overall, this is a great pedal if you're looking to be able to fade loops or effects in or out, or modify volume levels in a signal chain on-the-fly to get different levels of crunch or distortion in your sound for example. There's nothing else like it available over the counter anywhere that i could find, and I'd have no hesitation in recommending it if you need a pedal that does what it does. I've only had it 24 hours, but i can already tell it's going to be an indispensable part of my guitar setup from now on.
