Re: opinions on VOX Pathfinder 15R
I had 2 Pathfinder 15s, although neither had/has reverb. One of them has a 12AX7 tube in it, although i can't really hear the difference.
The clean sounds are good, but personally i don't like the overdriven sounds. I ended up swapping one of these amps for a Pathfinder 10, which strangely sounds better despite having a smaller speaker.
I usually set the amp up for the most ammount of clean sound, and then use pedals in front of it for overdrive. The clean sounds are good quality for a s/s amp, and i often use these little amps as a kind of 'reference' amp when changing pickups or making other sonic changes to a guitar, to eliminate the 'magical' extra qualities from a tube amp. The tone controls work well and i've never had any trouble shaping a clean sound to suit a particular guitar. The tremolo works well, too.
It probably depends on your particular application when using the amp, but if you are to use a s/s amp that has been provided, the Pathfinder is not at all a bad way to go. Of course the speaker can limit how much good sound you can extract, but that applies to any amp. I've used mine into larger speakers and it held up well. The Pathfinder's 15 watts won't be the same as 15 watts of valve power, and it will start to sound harsh at a certain point, but below that point they sound great.
Best bet would be to give it a good workout when you first get to plug in, run through the type of stuff you're gonna use it for and see what you get, and how much. But within it's limitations it should give you a pleasant and useable sound. Let us know how it pans out for you.
