Analog Speaker- and Miking-Simulator

With the Transducer a dream comes true: you can play loud without being loud! The ultimate D. I. solution for guitar amps is the first full alternative to cabinet miking that really rocks.
Via headphones you can play inaudible while the Transducer delivers authentic sounds even of the finest nuances of your guitar amp. Pure, high-quality analog design produces the same load like a cabinet and guarantees direct response with latency-free processing.
You want to record your fully torqued tube amp in a hotel at night? You’ll stay. Everything goes in studio and home sessions, everwhere, everytime – and without a sound booth.
On stage all problems with loud cabs and complex mikings are avoided. The artist can play with in-ear-monitoring at moderate levels, and a perfect signal in recording quality is provided for the live mix!

  • Authentic sound qualities and real time response for the guitar player – in contrast to digital simulations with latencies in processing
  • Independence from volume levels during performances or recording sessions
  • Independence from room acoustics in recordings
  • Provides for a live signal in recording quality without crosstalk from miking
  • Great space and weight reduction in transport

GITARRE & BASS, Report on Musikmesse Frankfurt:

"Of course we know about the most new products also before the fair starts, so we are more busy examining instruments and devices than looking for surprises. However, sometimes you discover a hit though, like this year in hall 5.1 at the booth of SPL, renowned manufacturer of studio gear. The developer himself demonstrated the ultimate D. I. solution for guitar amps: the Transducer. This 2 U unit elaborately recreates the load reactions of a loud speaker. Switches allow to choose from different cabinet and microphone simulations. It was impressive during our rehearsal how variable and real the Speaker Action and Miking Level controls shaped the signal. The signal quality is simply convincing, substantially better than anything in this sector up to now. Our editorial office is considering a centralized order – with a price of approximately 1100 Euro the holy grail is even affordable."


Tonehunter and SPL

The Transducer is a cooperative developmental effort between the guitar amp firm of Tonehunter and SPL. It brings together many years of experience from the professional music scene, combining specialized knowledge of electric guitarists and SPL‘s established international reputation in the research and development of analog studio electronics. This mutual effort of these two firms has been the basis for new ideas such as the unique Transducer concept, which has the potential to revolutionize the working life of both the electric guitarist and the recording studio engineer.
