Sound — 8
The Twin is easily one of the cleanest sounding amps any guitar player will ever play. While the volume is loud, that's not what's most important. The tone of the amp is gorgeous and since it is only a clean amp, adding pedals to the mix makes that tone breathe. Depending on what kind of guitar you're using (strat for me) there's never been a problem with buzzing or any other issue. It plays wonderfully in all environments and is quite versatile concerning what style of music you like to play. However, it does not suit all styles.
Overall Impression — 8
Overall, the Twin Reverb is a fine piece of equipment from Fender, but there is one issue that anyone must think about before purchasing. When I bought this amp back in 2006, I was really into classic and alternative rock, which was perfect. However, being a normal person, I have changed my playing style in the complete opposite direction. I am a doom metal fanatic now, and the Twin IS NOT suitable for any form of metal. It really is a drag, because I dropped so much for this. But I simply cannot deny how beautiful this amp sounds and how powerful it is. If it did get stolen, I must admit I would invest in a different tube amp, but if you love anything but metal, you just can't go wrong here.
Reliability & Durability — 10
This thing is a beast, for sure. It feels like it weighs a ton, which can be annoying at times, but it's definitely durable and reliable. Never has the amp broken down on me, and I changed the tubes only because of personal preference. Really the tubes inside were already great. I have a backup, but I don't think I'd ever need it if I gigged with the twin.

The Twin reverb, while pricey, is surprisingly not too complex. The amp consists of only two seperate channels, both of which are clean. One channel is "normal" containing two input jacks and volume, treble, middle, and bass knobs. The other is the "vibrato" channel, where the real meat of the amp is. Here you have your reverb settings, along with tremelo speed and intensity. If you use the foot Switch that comes with the amp, there's really no need to use the "normal" channel on the amp, as with the Switch you can manipulate reverb. And even though it's only packing two 12 inch speakers, this amp has ear splitting volume, especially if the tubes are changed to your liking.
