So.. I got this Vox Cambridge V9159 used off facebook. Apparently the man who owned it had a music store and this was his little amp he played at home in his dining room for fun. This man passed away and his son is selling off his music stuff that was left from the store and what not. I liked it mainly for the price and I thought the sound was good enough when I went to check it out. I don't know exactly when it was made but from looking into it it looked like a model that was produced around the year 2000. Anyways.... to my point. It seems like the more I play it the more..... zippy it sounds. In a good way. Is that possible? At first the clean sound was a bit..... lackluster but now it seems like it's livened up. I realize that it's a solid state amp with a tube preamp and I've always dialed in a little bit of gain and a tiny bit of vibrato that you don't even notice, to get some warmness from the tube. Which seems to work. But it seems like lately I've noticed a more.... I don't know it's hard to explain but a bite to it and resonation when I'm playing it clean with the gain way down (has a gain knob and a volume knob) that wasn't there when I first got it. It has always sounded really good with the gain turned up a good amount but even that might be a more biting now. I don't play it very loudly mostly but it has gotten a workout a few times. Is that possible? Almost like the circuitry and stuff sounds a bit better now that it's had energy running through it somewhat regularly. It probably sat for a while. Not sure how many years but it was definitely not being used when I bought it. Either that or it's something with my guitar sounding better which I also bought around the same time. But that one wasn't as neglected I don't think. Anyways... I'm happy with it. I would've preferred an all tube amp but I didn't quite have the budget for it. I gotta buy tires for my car before winter and the budget is tight so I was trying to be wise with my money. I paid 110 for it. What do you guys think? Can that happen or have you ever noticed this before with any of your amps?
