What We Think

Swart really managed to blend everything -aesthetic, sound, and functionality- into the perfect 45-watt clean amp. Tons of in-your-face clean tone with harmonic richness and vibe and that lush Swart reverb that I, personally, absolutely love. The treble and bass controls combined with the 3-way EQ-switch really open up the amp for massive amounts of clean sonic exploration. This is a great amp for capturing the tone of individual guitars with very little coloration from the amp itself.

But man, if you dial back the master and really drive the amp...watch out! Underneath that lush cleanliness is a delicious-sounding overdrive tone that barks and growls like no one's business, but without the boom-iness that you can get with other overdriven high wattage amps.

If all of that doesn't pique your interest, check out the pictures and see the convertible head in all of its glory! It really looks fantastic sitting on top of the 1x12 speaker cabinet with a Celestion Gold, tubes aglow and throwing out glorious, rich tones! This amp is sure to be both a visual and tonal conversation piece! 

Manufacturer's Description from Swart Amps

It's finally in production after the long wait but like a fine wine, it's more than worth it. The all new SPACE TONE FORTY-FIVE, or ST-45, is a first for Swart Amps on a number of fronts. It's our first 45 watt amp that is built and dedicated to the 6L6 tube, this via our first production Fixed Bias circuit to get the MOST out of this great tube. It's our first offering with separate bass and treble controls. Bottom line, this amp just has STELLAR CLEANS, so sweet and alluring, with no trace of the mechanical. Picture an AST on clean steroids. This amp really nails that elusive harmonic richness while still sounding open and transparent. The real kicker? It's actually as beautiful as it sounds, with another first for us, a full convertible HEAD cab that can be removed to show this beast off in full glory. IT's an aesthetic masterpiece mated with the easiest access to tube rolling fun you'll ever find. The cab is secured with four heavy duty latches. This amp made Buddy Miller reach for ye olde checkbook after only a few minutes playing at NAMM. Can be paired with matching 2x12, 1x12, or 1x15. The 2x12 with CREAMBACKS is a winner.
