Vox Valvetronix AD50VT 50w 1x12 Guitar Combo Amp

Sound Quality

I play hard rock/old punk and a little power pop on occasion. I use gibson les pauls and explorers with humbuckers. I've played marshall heads my whole 20+years of playing, and some others along the way. I never use effects. This amp sounded great on the Vox and JCM800 settings. It sounded a lot like my JCM900 head and 2 x 12 cab with just it's one speaker! The higher gain models are a little noisy, but every high gain amp has that. The rectifier sound is horrible - I couldn't even hear it over my drummer at practice. Very good sounds, but not enough volume.


I played it for a long time at the store, then bought it and brought it home. After the first half hour of playing it in practice, notes started to tail off into a digital crackly sound. I'd read the manual and knew how to use/defeat the noise gate and all. The two other problems on that very first day: the "Power" knob (1 watt - 50 watt) on the back was unuseable in the full 50 watt position without making uncontollable squeal and noise. I don't have squeal with any other amp. So I'm paying for a 50 watt amp, but can only use less power. Then the amp was making crackling noises even when I had nothing input to the amp. At first I tried different cables and all, but it was certainly the amp. I'm pissed that these are unreliable and made like crap, especially since I was digging the sound. I could never play out with that.

General Comments

I wish it had worked. I liked the sounds. Effects were pretty bad, especially in the pairs, but I would use them much anyway. I may try one more in a couple of months. It's a shame that they can't put out a consitstenly working amp. I was looking for a nice portable practice amp/small (super small) gig combo that would save me from lugging a 1/4 stack and head around. This was almost it. Maybe I was just unlucky, but I just read another review the mentioned the same problem...
