What does the solid state rectifier do in the Blues Junior? What's the difference between a solid state rectifier and a tube rectifier?

A rectifier converts AC voltage into a usable DC voltage.

A solid state rectifier will give very fast rise time and response as the voltages are produced
very quickly. A vacuum tube rectifier will yield more to the player?s touch dynamics, sound
warmer and less harsh by some folks feelings, and give the compression and sustain in a
much different way than its solid state brother.

When one initially hits a loud note or chord, with a tube rectifier, there is voltage sag, in
some cases, a LOT of sag. As the note or chord starts to decay, the voltage then builds,
and what you have in essence, is a built in compressor / sustain device.

Some say the SS are more reliable. Some say the tubes sound better. I for one like sag in a tube rectifier.

Yep. I have a Mesa/Boogie Stiletto Ace that allows you to switch between tube and silicon diode rectifiers. The tube rectifier sounds a bit warmer and allows the sound to "bloom" more. The silicon rectifier has a quicker response and sharper attack, perfect for heavy gain sounds. I use the tube rectifier for clean sounds and the silicon diode for gain sounds...
