Los Angeles, CA (September 15, 2015) -- The new Doppler Stereo Guitar Amp by Siegmund Amplifiers defies convention with an original design Asymmetrical Frequency Soundstage dividing higher and lower frequency ranges into a 10" and 15" speaker inside a V-front cabinet that delivers a Doppler Effect pitch-shift Vibrato with a Leslie rotating speaker sound in stereo. The warm laid-back lower frequencies of the KT66 tube and slower 15" speaker provide the foundation and background of the soundstage, with the brighter and lighter frequencies from the EL34 tube and faster 10" speaker floating on top into the foreground. The stereo spread of frequencies let the ears experience a 3D effect with notes and harmonics continuously relocating in real time depending on their pitch.
Playing full chords gives a sense of expanding dimension surrounding the player and listener with sound waves from all angles as they get reflected inside the room. With increasing Vibrato and Reverb the sound turns into a phase modulating echo in 3D stereo, acquiring an organic-like liquid sound character from slow motion chorus to jitter vibe. An electric psychedelic experience induced by tubes and acoustical physics alone.
