Harley Benton Custom Line Thunder 99 Reviews

Great little unit but problems with the headphone output

I bought this pedal/power amp to boost my overall guitar volume and run 2 speaker cabinets at the same time (2x50W out is LOUD!). I play in a hardcore punk band with minimal effects. I have 2 stacked distortion pedals running into an Orange Terror Stamp which is being used as a preamp. I then connect the line out of the Orange to the input on the Thunder 99. It does not color the tone at all and just provides more volume to the speakers. This is exactly what I was looking for. 1 issue: - The headphone jack has a problem where audio is clipping no matter what I use for headphones or inputs to the pedal. Since my Orange Terror Stamp has a headphone out this isn't super important to me but it would have been nice to have the unit fully functional out of the box as it is not a used pedal and I did pay full price for it plus international shipping to the US.

Good Little Stereo Amp

Does What its Supposed To

Very surprised

It delivered a decent amount of power. It works out great for a small paddle board and is able to power to being used as FRFR

Doet wat ie moet

Gekocht om Boss GT core in stereo te kunnen gebruiken. Doet ie perfect!

Mini stereo amp

Lads, If you know what you need, a tiny stereo PA (my use) , or using with guitar, this device is a killer...

didn't work

arrived set it up as instructed had to find a new kettle lead to power it with the correct fuse and ratings as the adapter sent was incorrect ,returned for a refund . i was looking forward to using it but wouldn't power up .

Unbelievable Value in a small footprint

I have been looking for years for an easy solution to play in stereo without two amps and this has delivered. I know the Carvin Mach 100 is the same unit but this is still 2/3 of the prices with shipping to North America. I don't know why other amp and pedal manufacturers haven't jumped on this band wagon.

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

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.

Perfect solution for stereo portable setup

I use it for my Fractal FM3, its not the most powerful amp, after all its a pedal size amp BUT enough power to drive 2 2x12 cabs for practice or small rehearsals.

I even did a small club gig with it once, works excellent.

For what it costs + size + what it does, highly recommended

Easy way to get a stereo FRFR if you have PA or monitor speakers already!

I already own a pair of lightweight Fun Generation 12" PA speakers. Adding this and a couple 6.5mm to Speakon cables to my pedalboard gives me a very lightweight full stereo FRFR setup that is as easy on the back as it is on the wallet. Win-win in my opinion!

Cool stuff

I won't lie, i haven't had a chance to experiment with it much yet but it powered up my 10 w amp enough to power my v30 Harley Benton 2x12 as I'd hoped and I'm building a pedal board based rig right now to experiment more with it and hopefully I'll be able to play with a band with this rig when I'm done

Must have for the HX stomp

I’m gonna put up a video on YouTube

This is a must have for gigging guitarists with modelers

Brilliant

As a UK musician touring Europe, it is essential to travel light. How much lighter can you get than this wolf in sheeps clothing.! Couples with the Line 6 HX Stomp a treat

Great sound from a small pedal sized power amp.

You'll get full power if you use 4 Ohms. I bought a Radial Cabinet Merger and use two 1x12 Celestion Speakers both 8 Ohms running parallel into the Thunder 99 at 4 Ohms. Killer sound.

Great Quality, Great Value!

Purchased from the USA and with shipping still a great deal! Sounds excellent! Line in and phones out really increase the utility. Plenty of power to drive stereo Fender single 12 cabs.

Power supply side is requisite with the quality of the unit. Not a problem and expected.

Does just what I need it to

I'm setting up a compact, pedalboard based stereo setup and this is a really great piece of kit. I haven't experienced the shock issue some have been reporting and the sound is powerful and neutral. The only minus point is the size of the power supply, but it still squeezes under my board (just). Highly recommended.

Problems running in stereo over a stereo/mono cab

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.

surprisingly loud

powers my stereo 2x12 to levels loud enough for any small venue. the only bad thing I have to say about it is that the power supply is huge!

Will not operate in stereo at 16 ohms. Shocked me.

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 :)

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.
