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...

Works as it should and sounds great - not shocking at all

Drill-Head 01.11.2022

Bought this for use with a NU-X MG-30 mostly as I am trying to downsize the shear weight of my live rig. Have used it with a custom wired 4x12 and a home made 2x12 and so far it works exactly as it should. No issues with being shocked as mentioned in other reviews. I am in the USA and I had to supply my own plug for the power supply and I have no problems. This little thing works great it is plenty loud in the 2 configurations I mentioned that I am using it in and it doesn't seem to color the tone of my patches very much at all. I do wish it had some built in tonal adjustments on the pedal but not really necessary.

Both cabs I am using (though not at the same time) are wired for 4 ohms per side stereo and neither the Thunder nor the PSU gets hot at all.

So far so good - If the GPA 100 could use USA 120volts directly I'd buy one or two of those as well. This is the first Harley Benton gear I have purchased that wasn't a guitar. All 3 of my HB guitars are amazing so I took a chance on the Thunder 99 and I am glad I did.
Thanks.
