BQ 500 Bass head
Jezzaboy, 09.03.2019
I bought this just before Christmas intending to use it in the house as a practice amp plugged into my computer. At the same time I was looking to buy a decent DI box but having read the specs and for the price, I thought I might be able to use it live.

One of the things that attracted me to this amp was the line in and headphone socket, something every amp should have but some don`t which is crazy in this day and age when playing through a amp isn`t practical due to noise.

Using as a practice amp, this unit is ideal, small with lots of sound available via the eq and a nice compressor via the Thrust function.

Usually I gig with a Ashdown ABM 500 but on my last gig at the last min, I decided to take along the TC as a back up. As it fits in a laptop bag, I stuck it under the car seat. At the soundcheck, my ABM started to play up, a loud buzzing noise making it unusable. "Have you got a di box?" asked the sound man, I have a spare amp I said. Got the TC out of the cab and plugged it into the Barefaced cab not knowing what to expect.

Well, after a bit of tweaking with the eq, I got a sound I liked and I must say the small TC done good. Even the band mentioned how good the sound was. Good sound out front as well.

So what I have is a small class D amp that saved the day for the the price of a decent effects pedal, a great home practice amp and a 3 year warranty from Thomman.

Will it replace the ABM? I don`t know as I love the kick I get from a old style amp but I would have no hesitation in taking the TC along and gigging it in the future. And even if I use the ABM the TC will be coming along just in case.

Basses used: Fender Nate Mendel P bass, Sandberg California P bass.

Amazing for the price
Loris2011, 05.01.2021
I've compared this little amp to many others before deciding to buy. Its really incredible how much power it packs. At the moment it drives 2 GK cabs for 500 watts together and it doesn't feel like its breaking a sweat.

The sound is really natural, it feels like there is little to no digitalization going on which is cool for a class D amp. Personally I like to have a rather sterile sounding amp. You cannot go wrong with this guy for the price. Do not buy this amp if you are looking for a ton of options however since it only has a simple equalizer and some compression which does not seem to do a whole lot.

Finally it looks and feels very nice. Clean finish and solid production.

Tiny powerhouse
marcus_j, 15.03.2021
Small, light, cheap, powerful and no unnecessary features. Nice, clean sound and the compressor is really useful.

I was a bit worried that the fan would be a bother for practice but either the fan doesn't work at all (which would, of course, be bad) or it's temperature controlled and only kicks in when you have been playing loud for a while and the amp electronics start to heat up.

Super lightweight and super loud
Jason S. Thompson, 18.03.2021
I purchased this head to be used for live applications both in the EU as well as US (universal power babyyyy!) and also because it is EXTREMELY lightweight and VERY loud.

Full disclosure - I ended up returning this shortly after it arrived because the bassist in my band changed minds about having 2 heads, and we kept the Quilter BassBlock that we've been using for the past year or so.

The Quilter has some more gain controls and I feel can be used effectively without pedals, while the BQ500 doesn't have much texture on its own. It's a great power amp, and if you want simple (yet tweakable) controls for a pure tone - the BQ500 is great for you. If you rely on pedals for your tone shaping - GET THIS AMP and use it as a power amp.

The compressor feature is interesting, but I prefer the tweakability of pedal compressors rather than a built-in knob. But again - this is just an added feature so no harm in it being there!

All in all - I'd recommend this head if you need an amp to make your pedal tones LOUD. If you're looking for a bass head with some more character, however - I'd recommend a Quilter BassBlock ;)
