I'm very close to pulling the triger on one of these. It was between this and a Rectoverb. I allready have a JCM800. I plan to AB Avenger with Marshall. I'm wondering if the HR50+ would be a beter choice for about $500 more. I really only play with the gain up. How does the low imput sound on Avenger? I'm stocked about getting it. I'll stick with the 5881s it comes with. Who here has one? How is it?
