Problems running in stereo over a stereo/mono cab
Boef, 01.01.2021
This little amp is quite a wonder. It has 2x50 watt (by 4 ohm) independent stereo channels and gives enough clean volume for a club gig at 8 ohms too. The sound is excellent and in comparison to my Pearce Gr2 the sound of the thunder 99 is a bit thicker. I had a problem running it in stereo over a 2x10 (16 ohm speakers) cab that was wired for stereo and mono use. Solution is to use a breakjack on both the (-) and the (+) of the cab, when using it in stereo. A cab wired for stereo and mono, uses a breakjack on one of the speaker (+) inputs to allow for stereo use when a second jack is inserted and mono use when this second jack is removed. On standard stereo/mono cabs like Marshall both the (-) of the speakers are connected together. This gave the problem that the Thunder 99 stuttered and gave no signal when using my tremolo/panning effect which threw the signal back and forth from left to right. I don't know why this problem only happened with the stereo tremolo/panning effect and not with any other stereo effects from the same pedal. So this problem can be solved by using a breakjack connection not only for the (+) but also a breakjack connection on the (-). I discovered this problem because it didn't occur when I used 2 separate cabs. So it's a brilliant and loud power amp with a great sound. I think a lot of Kemper users will be happy with the Thunder 99.

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...

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!
