Undertone Audio MPEQ-1 Preamp + EQ  From Undertone

This is the Pre/EQ circuit pulled directly from the legendary Undertone Console. If you want flexibility and versatility in your next preamp channel, look no further.

Undertone Audio

What We Think

From separately bypassable transformers on the input and output, to extra loading of the output transformer and being able to pad down the input and/or output, this mic pre will cover a LOT of ground for you, all while still being quite intuitive and straight forward. 20 minutes with this preamp and you'll know how to drive it to get the tone you need to. The EQ section is equally flexible with a fully parametric EQ that also has variable shape to help you achieve EQ tones similar to many classic sounds. The EQ can certainly seem overwhelming at first glance with all the variability right there at your fingertips, but don't be scared. In practice, it's actually quite easy to dial in just what the track needs.

This unit is an absolute chameleon, but without many of the pitfalls that can so frequently come with such widely variable tools. 

Manufacturer's Description from Undertone

The MPEQ-1 is the amalgamation of the UTA EQ and our new custom mic pre.  It features the same flexible and musical Class A discrete circuitry, the uniquely powerful HP/LP filters, and an exciting new approach to a Class A mic pre.  You can use the equalizer and the mic pre separately or as a complete channel strip.  The mic pre has a custom input transformer and a carefully chosen output transformer. Both are optimized to accentuate the most flattering sonic qualities inherent in audio transformers.  The unique mic pre design makes both of these transformers bypass-able.  This offers users a choice between the detailed clarity of a Class-A transformerless design or the vintage musicality of a dual transformer mic preamp.
