Your general opinion of this product.
I didn`t know if I was going to like this amp the first day I had it. On day two I decided to have a look inside, I found they had it loaded with some no name Chinese tubes. I dug around in my tube accumulation and found some good Russian made Groove Tubes and installed them, this gave an instant tonal improvement. I think Vox is doing this little amp an injustice by not using better tubes.
I then began to wonder about the Chinese made Celestion speaker that came in it so I ordered a Jensen Mod 10-35 and installed it. The little amp now sounds more articulate, with clearer highs, nicer clean sound, and it still overdrives nicely when you increase the gain.
More experimentation with other tubes may reveal even better improvements in tone. Don`t be afraid to experiment, it can add further enjoyment to this well put together little amp.
