Simply unusable
F#, 06.04.2020
I read too many negative reviews of this product yet I decided to trust a Thomann product due to it's Thomann in house brand and usually I am fine with their stuff and I end up buying it attracted by the promoted features . But ho boy how this product disappointed(I don't even want to call it an amplifier) reached a level of rarity that I encountered not so often.

Pro: it's small. period.

Cons: One con to rule 'em all => It is not properly electrically isolated (log story short) and it makes and heck of a noise that you can cover only if you are playing or can be attenuated if you just touch the strings of the guitar. not what i want to have to deal with or to do . it's happening just with this device, with other amplifiers I do not have and never had such kind of problem.

I still have trust in Thomann products. And I will try to have it replaced despite I received it just a little bit over than a month ago.

Have a nice day!

Great idea...but
SlackboyJim, 03.10.2019
I got excited about this product early on in 2019, and ordered it for arrival in July. Product arrived ok, and worked a charm with Mooer compact preamps meaning I had a HUGE amount of tonal and volume choices from a very compact pedal board. The Thunder was loud enough in to 2 x 12 to keep up with drummers in bands (match that impedance, though!!) and was "clean" and uncolouring. Even the size of the volume meant I could gently ride my level when the band got excited. BUT....
After 1 month of use I found I was getting electric shocks from the unit. I isolated it from the rest of my gear and so ONLY the pedal and PSU were in use, and sure enough 5-8V were measured. I could "solve this" by plugging in to an earthed product but that isn't right. Unit is being returned and I'll update you when I have news...

Good value for money
LooneyLoo, 19.11.2019
I have an AX8 and bought this to power my 2 x 12 cabinet. I gig weekly at a relatively big venue and wanted something that would compete with the drum volume level. It does it's job fine and I find it quite transparent, it does not colour the sound. The only issue I have with this is that sometimes I get electric shocks from touching it!! it's quite annoying and I usually avoid touching it when it's powered! Apart from that it's a good budget power amp. Don't know if I would recommend it though because the electric shock issue is quite a problem for me...

perfect for its price
ettern00b, 15.12.2019
I was fairly impressed with what this poweramp pedal brought to my setup. for it's price it does exactly what you'ld expect.

No more lifting heavy amps for gigs.

Nice feature: you can even use this pedal with 2 instruments together. When both inputs and outputs are used, the Left will only output to de Left and the Right input will only output to the Right, zo this pedal saves the weight of 2 heavy amps for gigs.

One of my best purchases i've done on Thomann

Con : the adaptor is to large (it's larger then the pedal itself)

Will not operate in stereo at 16 ohms. Shocked me.
AdamCham, 29.01.2020
Will not operate in stereo at 16 ohms. literally shocked me when touching the input cable and my guitar strings.

If using this to power two cabinets ( presumably under 16 ohms ) It sounded great and was plenty loud to keep up with loud drummer.

The power supply is very bulky and is comprised of cheap plastic.

When connected to the HB 2x12 cabinet in stereo mode, it pops and cuts out when i strum.

I cannot recommend this if you plan to use 16 ohm speakers in stereo.

works as advertised :)
Poo Ninja, 20.12.2019
I've only had it for a week sounds great and works with 220v 50hz and 110v 60hz. You 110 folks will need to swap the power supply input cable for US outlets (you probably already have on on something your not using.) So far plenty of power for small jams etc
I'll edit this post after pushing it to the limits :)
the mute switch is great for silent start up and shut down to prevent damaging sound from pedals or processors from hitting your cabs.
