I use this in the effects loop of both my all-tube and solid state amps, and it sounds great with either. I use it for all kinds of overdriven sounds, both rythm and lead tones. The first channel is great for classic rock to 90s rock, like AC/DC, Extreme, etc., the second channel has lots more gain; I mainly use that for sounds like Satriani, Metallica, etc., but if you play modern heavy genres, it has lots of oomph for palm-muted runs as well. Great, tight bass response. When tapping, each note is clear with lots of definition. On lower settings, the unit is noiseless. With extreme amounts of gain it has some noise, which is to be expected. I get a lot less noise with this than when I was stacking drive pedals to get my overdrive sound. It can do very trebly, sharp tones, but it has plenty of ways to shape the sound, and since I mainly play Guns n Roses and similar tones, I've turned the mids up and the treble down, giving me more Marshall'y tones. Workmanship and finish is solid all around, my only slight complain is that I was unable to detach the rubber feet because one of the screws was stuck in its thread from the factory, so it simply couldn't turn. I haven't tried running it directly into the front of my amp, but Victory recommends using it in the loop, so that it can replace your amp's. Thanks to this I was able to retire several of my drive pedals; I simply don't need them as I can now get all the different drive tones from my amp. One thing to be aware of is that this pedal does not do clean tones, it goes from pretty crunchy/Hendrix-style drive up to insane overdrive. Also, the EQ controls are shared between both channels, which I don't mind, but some people might not like.
