We're into some really rare and amazing territory here.  If you thought the stash of tube amps I've been posting are something to see, this is going to blow your mind!

The JTM45 Bluesbreaker of the most sought after and legendary amplifiers known to mankind.  This example is as clean as they come, and it is excuse free as well.  

Some capacitors have been swapped out when the amp came into the states and went directly to Don Butler's shop.  The removed parts are included.

Original Celestion speakers with June 1966 dates stamped on the speaker gaskets.

This amp is a beast.  It is being listed with the amp's price and a handling fee only.  The handling fee covers the cost of the time and materials well use to pack this beauty for safe shipping.  Shipping cost will be determined when a buyer steps up.  We will build a shipping crate for the amp and will ship the chassis separately as the weight of the transformers can cause issues with the aluminum chassis.  So, if you want to buy the amp please understand that there will be some assembly required. 

It could take us up to 5 business days to prep the amp for shipping.  Local pickup is available as well.  If someone in the Pacific Northwest is interested in the amp, we will have a van leaving Chico, CA early in April for the Seattle area.  Local pickup or shipment on that van through Oregon to Washington State.    

We could also bring the amp to Nashville for the vintage guitar show, the weekend of March 25th.  The handling fee would cover the cost of shipping to Nashville.  Pickup would have to be made in Franklin, Tennessee.
