The TC Furlong Sesh 400 is a meticulously crafted steel guitar preamp pedal that pays homage to the revered 1970s Session 400 combo amp.

Built in the USA, the Sesh 400 boasts a 100% discrete transistor circuit—meaning it contains no integrated circuits (ICs). This design choice ensures a more organic and dynamic response, closely emulating the original Session 400's analog warmth.

  • Treble: Controls the high frequencies.
  • Mid Shift: Alters the midrange frequency center.
  • Presence: Adds brightness and clarity.
  • Sensitivity: Adjusts the input gain for different playing dynamics.
These controls provide a wide range of tonal possibilities, allowing you to dial in everything from smooth, mellow tones to bright, cutting leads.
  • Authentic Tone: Faithfully replicates the vintage Session 400 sound.
  • High-Quality Build: Premium components and construction ensure longevity.
  • Versatile Controls: Extensive tonal shaping options to suit various playing styles.
  • Portable: Compact design makes it easy to transport and integrate into pedalboards.
The TC Furlong Sesh 400 is a top-tier preamp pedal that captures the essence of the classic Session 400 amp. Its all-analog, discrete design and versatile controls make it an excellent choice for steel guitarists seeking authentic vintage tones in a modern, portable format.

Okay, enough of the data-here’s my take. I am currently running the Sesh 400 pedal after my Benado and into a Ganz Straight Ahead power amp, then into a variety of cabinets depending on what I am feeling that day. The controls are very sensitive, but each EQ function is perfectly in tune with where a steel guitar’s needs to sit in a mix. The Sesh 400 gives me the vintage Peavey tone that I really love to hear, and it’s much less weight to carry around. I currently have a variety of solid state and tube amps, but the Sesh 400 is definitely going to be my go to for quick and great sounding tones. I was fortunate enough to pick this pedal up used on the Steel Guitar Forum for a fraction of the new price and after using it I would gladly have paid full price for it. Try one out, you won’t be disappointed.
