It sounds like you want to buy a amp you have never heard. That is like buying a house you have never looked in. The sound of the guitar is a driving force and part of that force is the amp. You will get to a point that as you play you will feel a force move through you, moving into your guitar then to the amp. You need a amp you love the sound of. Everything can’t fall into place if you do not like the tone you are hearing to go with the feel moving through you.
