This amp is absolutely nuts.  It is so warm and sweet sounding. 

The vibrato is of the pitch-shifting variety and it is wild.  The reverb is full, deep and rich, and you can send it way over the top if you want. 

There is a high frequency horn driver that adds to the frequency range.  You can hear immediately that there is more going on here than in just about any other amp.  The Jensen C12N is original and isn't hurting the sound - what a great speaker!

Transformers are original.  

The auxiliary speaker outputs just the reverb sound and adds a fifth dimension.  If you separate it from the amp it is even more amazing.

The amp runs quietly and soundly. 

Parts all date to mid 1973

We will ship this in two boxes to make sure that the chassis will be secure.  There will be some work to do when you receive the amp.  If you are not down with this, please arrange to pickup in person.
