6stringbassist Posted May 9, 2008 Share Posted May 9, 2008 (edited) I've been using this with my Bergantino IP112, it's a fantastic sounding tube pre/DI. It's basically brand new. I just prefer the solid state pre's that I've got, and I've just ordered yet another, so this really is just sitting around doing nothing, which is a total waste. £225 ono including shipping. This is from the Summit website. The TD-100 instrument preamp and tube direct box from Summit Audio features a hybrid signal path utilizing both a discrete solid state output device and a 12AX7A/ECC83 vacuum tube to give your musical instruments the clarity of class A sound with the richness and warmth of vacuum tubes all in ½ rack space. Perfect for both live and studio use, the TD-100 offers both XLR microphone level and ¼" TRS line level outputs, plus variable input impedance, polarity switch and ground lift, signal and overdrive LEDs, and even a headphone output for use as a practice device. All with the quality that says Summit Audio. Additional Information: Basic Operating Instructions Product FAQ How can this little box improve your sound so drastically? First is the variable input impedance control (loading). By lowering the impedance on the TD-100 your instrument's pickups get loaded down, changing their tone and the way they react to the string vibrations, generally making the tone darker and quieter. Raising the impedance lets your pickups work without hindrance, opening up the sound with a slight increase in gain. Use this to make your instrument sit properly in a mix without EQ or other tone shapers. This effect works best with passive pickups. The second way the TD-100 improves your sound is with the transformerless vacuum tube based circuitry. This vacuum tube isn't made to distort and pervert, it adds a subtle texture and smoothness, a professional sheen to your instrument. Try the TD-100 in your signal chain, live or in the studio, with guitar, bass, keyboards, or any Hi-Z instrument and see what a little Summit Audio can do for you.

birdy Posted May 10, 2008 Share Posted May 10, 2008 Bump for this awesome preamp. I have one of these and it really warms your tone up. Its hard to describe sound with words but I would say this adds somewhat of a 'creamy' texture to your sound. Steve Link to comment Share on other sites More sharing options...
