The Telstar blends the sinewy harmonic assertion of EL84s with the deep full control of 6L6s in a new and unique push pull recipe. You may have a 6L6 amp or an EL84 amp but not an amp that uses both types in harmony for a new pallet of expression. The Telstar sound can easily range from haunting rich cleans to creamy overdrive. Our Lean/Lush switch tailors the body of the tone while the 53/58 switch changes the overall gain structure and the frequencies the Tone control emphasizes. Sonically treading the years from early Fullerton 50s roundness thru late 50s proto British bite.
