RetroValves are 100% analog vacuum tube replacement devices offering the warm, fat, punchy sound traditionally associated with only glass vacuum tubes. RetroValves are pin-for-pin compatible with 12AX7 tubes in nearly any guitar amplifier, offering instant modification of preamp gain characteristics. Red RetroValves are very high gain, Amber are standard gain and Blue are lower gain, allowing the preamp to achieve gain characteristics not possible with standard vacuum tubes. RetroValves are very low noise and have no potential for the microphonics sometimes characteristic of vacuum tubes. And because RetroValves operate with much less heat and consume less power, they reduce stress on the amplifier's electronics.

So far AWESOME!!
I give this 4 stars because it will take years to see how they actually hold up. But so far these diodes are a fairly cheap, great upgrade to a high gain amp. Could easily take the place of a signal boost or low OD pedal. And the less pedals in a chain the stronger the signal. So far it seems like these diodes could take over triodes all together. AND really easy to swap out if your new to working on amps.
