Greetings! Up for trade is my EBS Valve Drive v.2. Like new, works great, sounds incredible. The richest, deepest bass distortion I have ever used, it really kills, HUGE low end. Unfortunately I was hoping it was more of a spiced up pre-amp, and it does not do what I want in that regards. I would like to trade for a Darkglass B7k/B7k Ultra or a B3k and some cash. Also open to other (real) tube preamps like Demeter, I can throw in cash on my end. Ships in original box, with original 9v A/C adapter. I'll ship ConUS for 10$, so 270$ total. Shipping outside of ConUS is at buyer's expense, if interested, and I take no responsibility whatsoever for what customs might do to it.
