Sustainiac vs Veyz Sustainer

Sustainiac installed in a 1985 Ibanez Roadstar II [RS-440]
Bridge Pickup = DiMarzio Super Distortion
Peak Current Draw @ 9VDC = 42mA

Veyz Sustainer installed in a 2022 Epiphone Alex Lifeson Les Paul Custom Axcess
Bridge Pickup = Epiphone Probucker 3
Peak Current Draw @ 9VDC = 200mA

I have installed the Sustainiac in 5 guitars and am really invested in the sound and control, but, I liked the gold hardware look of the Red Ruby and Maniac Music does not have a gold cover sustainer pickup. I came across Veyz that had a gold cover pickup that integrates the sustainer driver and a separate neck pickup under the pickup cover.

From the Video, it seems that the Sustainiac has more "power", but that may be due to the difference in Bridge pickup that the sustainer uses to create a feedback loop. The Ibanez Roadstar II has a DiMarzio Super Distortion and the EPI Red Ruby has the EPI ProBucker 3. The Veyz Sustainer has a Gain control that is presently maxed out... I will try to raise the Neck pickup a bit to get the Sustainer Driver closer to the strings.

I measured the Peak current draw of each system to see how the systems 'eat' batteries... the Sustainiac has much lower current draw which means that the battery will last longer...
Veyz Sustainer Peak Current Draw @ 9VDC = 200mA
Sustainiac Peak Current Draw @ 9VDC = 42mA

The cost of the Veyz is about 1/2 the cost of the Sustainiac.

It took a while [more than a few months] for my Veyz Sustainer to reach me after a few prompts over What's App, but this was the risk that I was willing to take to get the 'look' that I wanted for the guitar... thankfully I received it and it looks and operates as expected.
