AMT TC-3 Tubecake

Effects PedalThe AMT has recently brought some truly impressive pedals with tube preamps and distortions.

The Tubecake is possibly the smallest power amplifier on the market, practically designed as a complement to the above-mentioned pedals that are around now. 3 watts in pedal form; adjustable in volume, presence and resonance (the low frequencies as a power amplifier can be adjusted here).

The point of the pedal is to not have to sacrifice the total dynamic power of a tube amp even when playing at low volumes (when recording, practicing at home or in small clubs, etc.). That is exactly what the Tubecake impressively masters.

Any 8-ohm cabinet can be connected. And by the way: 3 watts is not exactly quiet ....

This pedal is a small power amplifier which packs a lot of punch for home playing at least. It has controls for volume, presence, resonance and the speaker out is 8 Ohms. Presence and resonance gives you some options to shape your tone, but I find that resonance is more like a eq-like bass boost which hinders it's usability. Also if you are critical, the playing is not as sharp as on real tube power amps. But the purpose of this pedal is different so, I think it's a good partner for your favorite preamp or pedal for playing at home.

Remember to buy the power supply which is sold separately.

Good Tone, Could do with a bit more power.

Angelus502, 28.03.2016
Great sounding pedal but wont get over a vigorous drummer. Perfect for practice, or jamming with a buddy (maybe a quite band practice) if you don't want to drag a head around.

The tone out of this little power amp is great - better than the Harley Benton GPA-400 power amp (class D), better than my old low end solid state practice amps I still have kicking around, but its missing that special something only real tube amps have. So tone wise its about up there with a good solid state amp.

Power wise, hmm it does get pretty damn loud for a little pedal amp. But I'm pretty sure its not going to get over a drummer without a PA (I haven't played through it loud in a while). There is a youtube vid of a guy using a pedal board with a TC-3 and a 1x12" Cab thats mic'ed up and angled up as a personal fold back, but that's about the only way I could see it would work live.

Another Con is its only rated for 8 Ohms. I did email AMT and they confirmed that they do not recommend using with a 4 Ohm speaker I had without wiring in some extra load. Im not sure if it will work with 16 Ohm. This should'nt be a problem for most people though.

Also I haven't tried using this with a quad box, I dont know how well it will would drive 4 speakers. I'll check it out and update this for you guys soon.
