PRODUCT DESCRIPTION
- Shape recordings with four tube voices The included UFO Tube Pack gives you practical tonal flexibility without adding complicated controls or menus. Each tube changes the character of your recordings in a clear and usable way. The pre-installed Electro-Harmonix 6922EH focuses on transparency and extended highs making it useful for detailed vocal and acoustic sessions. The 12AT7EH introduces tighter low-end response and articulate top-end clarity suited to bass clean guitar and ribbon microphones. If you want stronger harmonic texture the Sovtek 12AX7LPS delivers saturated mids with added colour while the 12AX7WA creates a smoother vintage-style warmth. Tube swapping is quick thanks to the removable transparent cover and spring-mounted design helping you experiment freely during sessions. Designed for clean detailed signal capture The UFO combines Class A discrete circuitry with carefully selected internal components to keep recordings focused and accurate. By avoiding integrated circuits and using discrete signal paths throughout the preamp maintains excellent clarity across a broad frequency range from 10Hz to 100KHz. Low-noise metal film resistors and polystyrene capacitors support accurate reproduction while balanced transistor amplification helps reduce crosstalk and unwanted interference. External transformers also help separate the power stage from the audio path for cleaner operation. If you regularly record dynamic performances or layered arrangements this design helps preserve detail and depth without relying heavily on corrective EQ or additional processing later in the mix. Ready for microphones and instruments alike Flexible connectivity makes the UFO easy to integrate into different recording setups. Balanced XLR inputs and outputs support microphones and professional studio equipment while the unbalanced 1/4-inch instrument connections work well for guitar bass and synth recording. Phantom power allows use with condenser microphones and the polarity reverse switch helps solve phase issues during multi-mic sessions. Additionally the -20dB pad gives you more control over louder sources before they hit the gain stage. With up to 68dB of available gain the UFO can comfortably drive a wide range of microphones including quieter dynamic and ribbon models. This adaptability makes it useful for home studios project rooms and larger production spaces alike. Classic studio styling with practical control The UFO balances modern construction with classic studio-inspired presentation. Its illuminated tube and analogue-style VU meter provide immediate visual feedback while adding a distinctive centrepiece to your recording desk. The minimalist casing keeps controls straightforward so adjusting gain monitoring levels and input settings feels fast and familiar during sessions.
