is there really a sound difference in these 3? because i found a good deal on a thd hotplate thats 4ohm and my 5150 and laney vh100r have switchable ohms. so if theres not really a difference then i may get this. im pretty much just going to be using it for recording direct into my interface and using redwirez irs. and i know alot of people like to be smart asses, assholes, arrogant tools, etc; on this forum. so if you feel like thats going to be you just dont even bother responding.
