Product Description

Summit Audio TD-100 Instrument Preamp and Direct Box - Half Rack Unit


Studio and stage


Maintain control of your sound in the most demanding audio environments. Get world class sound in the studio and on the road with the time-tested quality and rugged design of Summit gear.


24dB of gain


Plenty of gain for boosting low output instruments and to drive different levels in a rig for tonal variety, with the stepped pot making it easy for you to instantly recall your ideal settings.


Watch your tone, now...


One of the coolest features of the TD100 is its variable input impedance control, which lets you perfectly match it (or intentionally mismatch it!) to a wide variety of instruments and pickups, giving you the flexibility to actually change the sound of your instruments


Really well built


The Summit Audio design philosophy considers the entire package when it comes to crafting gear. We pay special attention to the details of construction and have included many refinements over the years so units are durable enough to handle the rigors of the road. That is one of the reasons why you will find Summit gear on tour with many of today’s top touring acts around the world.
