Summary: I own LM2 and when Markbass came out with TTE500 I had to check it out and was blown away how great this all tube preamp tube compressor sound as great as my old SVT 300. I sold my SVT when I got the LM2, but now I can get that tone SVT and sound again at only 13.5 lbs!!! I had to have it, yes I also bought the NY151RJ cab to match. I love it!!! I use my old LM2 for rehearsal and my new TTe500 for gigs. Most gigs I'm playing on 2, any louder I told to please turn down.
