Quality Unit that freed me from 6 Power Supplies!

King B1, 10.03.2018
So i had a few new pedals and was putting together a board for a specific project, that could also be used for jamming/practising alone. A number of these pedals have a heavy power draw ( EHX Superego Plus / SDrum / Jamman Solo XT / Zoom Multistomp), well in excess of 100 mAh; which is what my standard multi-power supply can handle. So my hunt began to find a new power unit to rid myself of all these individual supplies and fly, be free!

Thomann is always a good starting point and low and behold there it is! The golden chalice of unlimited power! Well, 2000mAh anyway.

Im running a wet/dry 2 amp setup with some direct feeds to the PA too, but most importantly everything on the board (around 13 pedals) are all running from this little beauty. Ive added a decent quality 3 connection daisy chain lead running off one socket. i use this to power the lower level pedals (10-60mAh) and due to the quality of the isolated outputs i have no issue. Remember the 2 golden rules - total draw is no more than 2000mAh and 1 socket can only pull 500mAh max.

For less than £45 you simply cant touch this unit. Its the same foot print size as a pedal and comes with good quality leads.

Only 2 things to say of note, that aren't criticisms but are worth being aware of;

Being a European company this comes with a European power supply. Momentarily forgot this but a quick visit to a well known African rain forest and for £5 i had an adapter to convert it that locked in place.

Second point is that its a metal casing and will get rather hot due to the amount of power drawn, dependant on the quantity of pedals used. its drawing a lot after all!

I'm very impressed with this so far and yet again the quality of Thomann's own brand gear inspires confidence!

Serves the purpose with nearly zero noise

Shawn Lim, 12.08.2018
I've had my first unit sent to me faulty, but Thomann quickly sent me a replacement and it was working fine.

1. Great for pedal boards which use a few digital pedals which use high current power
2. Has a 18v y-cable for those pedals which can receive higher voltages
3. Compact size and light weight

1. I've owned the HB Power Plant Jr. before, compared to that, there seems to be a slightly higher noise floor in my signal in the exact same conditions. Not sure why, but it is so little that it is hardly intrusive. I have a noise gate that takes care of that easily at a very low threshold level
2. Build quality of the metal finish is not the best, there are some sharp edges around the unit. Nothing that can be taken care of with some light sanding to smooth the edges
