American Tones with a Josh Smith Twist

Based on Joe Morgan's original PR12, the Morgan Amps JS12 Josh Smith Signature all-tube combo guitar offers the Blackface-style tones of the original design while offering some top-shelf tweaks that Smith demands. Loaded with custom Mercury Magnetic transformers, a custom-designed Eminence JS1250 speaker, and a 3dB boost, Smith's signature amp takes the classic sound to a new level. On top of that, the JS12's tube-driven reverb boasts a dwell control for gorgeous ambience. Josh Smith carefully crafts his tone, and the Morgan JS12 1 x 12" combo is the amp he uses.

Boutique upgrades to Josh Smith's specs

The 12-watt, Class AB, fixed-bias Morgan Amps JS12 combo delivers tones reminiscent of one of Morgan's most popular designs with some extra tonal tweaks. The custom-made Mercury Magnetics transformers give the JS12 more low-end punch without losing definition. Based on '60s-era American amplifiers, you can expect detailed high end, a slightly scooped mid, and a full robust low. And because Josh Smith is a favorite here at Sweetwater, we were thrilled with how effortless it is to get his style of tone with the straightforward 2-band EQ.

Tube-driven reverb and boost

Get more out of the Morgan Amps JS12 Josh Smith Signature combo's reverb with its dwell control. The all-tube reverb circuit and spring reverb tank deliver the classic sound you know and love. The dwell control lets you adjust the decay of the reverb to taste. You can dial in deep, lush reverb that won't mask your guitar tone. You'll also find a preamp boost that squeezes a bit more front-end drive from the JS12 when you aren't able to crank up the volume.

Simple controls unleash a wide tonal range

You can tell that Morgan Amps products like the JS12 Josh Smith Signature tube amp combo are made for hard-gigging guitarists just by looking at them. The simple control set conceals a surprisingly wide range of tone, but you'll never have to spend long turning numerous knobs to get the right sound. Grab a great guitar, plug in, and turn it up. If you liked the PR12, you're going to love the Morgan Amps JS12 Josh Smith Signature combo amplifier.

Morgan Amps JS12 Josh Smith Signature Combo Features:

  • 12-watt, American-voiced combo with reverb
  • Custom USA-made Mercury Magnetics transformers for boutique-like sound
  • GZ34 rectifier
  • Custom-designed 12" Eminence JS1250 speaker
  • Fixed baffle design lets the entire cab resonate
  • 3-spring tube-driven reverb adds gorgeous ambience to your playing
  • Reverb runs parallel to tone stack and stays out of the circuit when not being used
  • Dwell control lets you set the reverb's decay

What is Demo Gear?

At Sweetwater, we're so picky that what we call a "demo" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

What demo means to us is that we've had it out of the box, or maybe it was in a customer's hands for a few days and isn't "factory fresh" as a result. Every demo item we sell has Sweetwater's 2-year Total Confidence Coverage™ warranty, and has been tested and verified up to "new" specs by our factory-authorized technicians to make sure it's in perfect working order before we ship it to you.

When you buy a Demo item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!

Morgan Amps JS12

Well when I first heard about this amp I was very skeptical about it. Especially since it's someone's signature model. In my 30+ years of playing these products usually fall short of expectations. This amp is AMAZING! Definitely exceeded my expectations. Although my original intention was just to use it in the studio, this amp is light and very gig worthy. Don't let the 12 watt spec fool you this amp has tons volume. It's easily louder than my Blues Jr. and my Soldano Astroverb both of which are 20 watts. Great with pedals even though all I use is a boost for solos. Clean tones are great and very smooth, I like the amp best between half and full volume. Breaks up great! This is my new goto amp for everything. Highly recommended

This Morgan JS12 is a Revelation

My only point of reference was my Blues Junior, and I knew there had to be new horizons out there. After tons of internet research, lots of advice and figuring out my finances six different ways, I cast my lot with this amazing Morgan JS12 combo amp. My wife's response when she first heard it, "Whoa, I thought an amp was just an amp. Clearly I was wrong."

This amp is a revelation, and I am so blessed that I get to play this every day. It makes me a better player, will make me play better, and I get to enjoy it along the way.
