What are you using them for? I have a ton of amps, but just bought the syn with the uber and slo. I bought it because I'm a basement player now with kids, and being able to turn it down, or record is a huge plus. But, when I compare it to my real amps, it is thinner. I can get it close, but it does not have the depth that a real amp has. If I was playing at volume like I used to do, I would go with a real amp. For recording or ease of use, syn.
