How to get a lower price, instantly!

Why do we do this?

By requesting an e-mail quote from us, you give us the ability to offer you a lower price than anywhere else on the web. A quote on the product will be sent instantly to the e-mail address you enter, and you can add the product to your cart at the lower price displayed in the e-mail.

What We Think

A truly spectacular value for tube budget compression. This unit is the perfect little single channel compressor for those looking to add a nice subtle tube compression to their tracks, and don't want to drop the $2K+ per channel for a box like the LA2A. The sound quality and fidelity of the box is a pleasant surprise... totally impressive little compressor for the money, and definitely on our recommended buy list.

Maximum flexibility

It's a family affair

Really well built

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's one of the reasons why you'll find Summit gear on tour with many of today’s top touring acts around the world.

Hand-crafted in the USA
