tc electronic BQ500 Bass Head

This is a really good class D amp for the money. Solid build and super clean sound. If you're looking for a lot of watts in a small package, you'll probably be very happy. However, it has no sonic personality of its own. It's like playing through a good PA amplifier. Don't expect the classic TC sound. The EQ is helpful but not colorful. The gain control is just there to set input level - don't expect any grit or overdrive. As others have noted, the compressor cuts a lot off the high end, so I don't use it.

I put a SansAmp in front of it, and that combination sounds great. When I want some grit, I kick in a TC MojoMojo pedal, which I bought for guitar but turns out to be fantastic for bass too. And if you want compression, you'll probably be happier with an outboard pedal.

Don't get me wrong, I'm thoroughly happy with this amp. I just wanted a power amp, and that's how I use it.

There’s a lot of different opinions online regarding bass rig set setups on what you should use and what to avoid. I got lost in the noise on many different forums speaking about this, but I decided to purchase this on reviews from people with the same outlook as myself.

I’m a very simple ‘plug in and play’ bassist, and this amp stood out to me because that’s what it allows me to do. With the pedals I use (distortion, chorus and an EQ pedal) it just amps up my tone and keeps things simple. 99% of the gigs I play have a sound guy and use a DI for FOH so it’s more than loud enough with a single cab that I use for monitoring on stage. Very responsive EQ to fine tune your tone! The ‘thrust’ compressor seems to have a minimal impact on the sound but it’s a nice feature to have (it’s still early days so it may be better than I give it credit) A compressor pedal would be more beneficial but for the price of this amp I don’t expect it to be groundbreaking.

Overall, this head is fantastic if you’re on a budget and want to upgrade from a very heavy combo amp (like myself) I can’t wait to get gigging with this thing and break it in!

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.

If you've never had your own rig and decided to buy one without investing too much money - this amp is the perfect option. It also could be a great backup amp as it's light and quite small.

Control: just a few knobs will help you to dial the tone you like. EQ is very understandable. However, Passive/Active switch position is reversed (known issue with this amp). Doesn't bother me, but might be a problem for perfectionists.
Thrust control is useless for me, but I tried and felt it cuts quite a lot of treble. Not my cup of tea.

Sound: I play STD Fender Jazz Bass through GK CX210 cab, for me the sound feels warm, transparent, with enough of punch and bass. Wide range EQ can help you to reach desirable sound.

Fan is not very loud, but I haven't pushed it hard yet.
I might change my opinion and add some more details in the future, but so far I'm pretty happy, especially for this price.

Add:
- 100~240 volts main input is the best thing TC came out with!
- With one 210 cab plays nicely with 2 guitarists and a loud drummer.
