Jet City Amplification RetroValve Red

I debated trying these for a long time and finally pulled the trigger. I'm glad I did! I am totally blown away! I got an Amber 3-pack & started swapping the V1, V2 & V3 in my old 5150. Starting with just the V1, there was a slight increase in gain & the very top-end rolled off just a bit. I'm not saying it suddenly sounded sterile or solid state at all-it still sounded like tubes-just a bit less presence bite. Then, I put the V1 tube back and switched out V2 and V3 for the RetroValves. I got all the sizzle I ever had PLUS more growl, better-defined mids, an overall "fatter", both low and high gain tone and that little extra gain. I'm not saying these are for everyone, but for the price of a good cable or used dirt pedal, you might get a really great sound you didn't expect from your current amp. If nothing else, you might be able to relegate them to your phase inverter or loop and not have to change them for a good, long while!
