JS12 – Josh Smith Signature Head

The Morgan JS12 Josh Smith Signature amp came to life years ago when Josh asked Joe Morgan to build him a killer small wattage amp that he could use on the Grammy’s playing behind Mick Jagger. The JS12 contains all of the mods that Josh asked for on his personal PR12. The hand applied aged lacquered finish is standard for this model as is the custom Eminence JS1250 speaker that was designed specifically to Josh’s exacting standards. Josh also had Joe incorporate a boost switch for those times he needs just a little more grit from the amp.

Around six weeks to build, and up to nine to twelve when the bench is full. Limited lifetime warranty.

What it does

The JS12 starts with the classic black face tone and then beefs up the low end by giving the power supply of the amp more juice so that it doesn’t fart out like the originals. The reverb has also been modified to add a Dwell control. The Dwell control allows you to control the amount of decay in your reverb. This allows you to have a very high reverb mix without washing out your guitar tone. The addition of the 3db boost switch allows you to get more grit even at lower volume levels.

The bass and treble controls interact with each other to give you a wide range of tones. As with all Morgan Amps the JS12 LOVES pedals and works well with any pedalboard. The JS12 is small footprint grab and go head that will cut through any mix and is loud enough to get over the drummer. This amp has been Josh’s go to amp whenever he is in the studio or on the gig battlefield.
