There is a lot of appeal to the fact that all Tone Hammers or any other production class D's for the most part sound the same as every other of the same model. SVT's can range from Voice Of God to unusable mud but oh man when you get a good one.....
It's like this: To find a great tube amp you have to be prepared to commit to a few that won't be "the one", make some compromises, spend a few bucks, learn as you go and exercise patience to experience the magic....kinda like finding (and keeping) a great woman or man.
SS amps on the other hand are safe, reliable, less expensive, easier to handle and do the job. But ultimately they lack some essential magic....more like rubbing one out.
