A 12-output isolated pedalboard power supply whose variable 4-9V rail is aimed at vintage germanium fuzzes.
Watch
Supercool Pedals' clip asks whether a power supply is ruining your tone, which is the question isolated outputs are meant to answer, and Home Studio Simplified covers why supplies fail.
Why it matters
Twelve fully isolated outputs cover two 18V rails, four switchable 9V/12V rails, four 9V rails, one 9Vac output and one variable 4-9V output, which is enough for most large boards without a second supply. Isolating each output keeps noise down, and the input is switchable between 115V and 230V. Cables, converter plugs and Pedaltrain mounting brackets are included, and the unit weighs 2.35 lbs.
Note
Truetone's switching-mode flagship brick, whose variable 4-9V output is favoured for vintage germanium fuzzes and whose isolated rails keep noise down on large boards. Sweetwater lists it at 4.8/5 from 184 ratings; Reverb's product record dates the model to the 2010s.

“The Problem: Many pedalboards suffer from power-related noise issues caused by poor grounding, daisy chaining, or improper voltage distribution.”
