The LA Custom Preamp for Fender Rhodes Pianos

 

Having restored Rhodes pianos since 1994, we observed that the Peterson design Rhodes preamp (circa 1970-1977) is more sought after by our clients and Rhodes enthusiasts than any other preamp in Rhodes history.

The original Peterson Rhodes preamp warmth became synonymous with the classic recordings in the ’70s and ’80s. Two miniature lamp filaments were used to create its unique “soft tremolo” effect, which can be heard on countless hit songs such as “Living for the City” (Steve Wonder) and “Just the Way You Are” (Billy Joel).

A well-known challenge with the Peterson model is its limited EQ response. Even when the treble is fully boosted, it can still lack the clarity and brightness required to stand out in a mix in many cases.

We developed our preamp using a rare prototype used by some of the leading L.A. session musicians. That prototype was a customized Peterson preamp, featuring the original Peterson gains stage and tremolo, with enhanced EQ which was tailored to address the lack of clarity while minimizing unwanted hiss.

Our preamp faithfully recreates this rare prototype design, employing modern, dependable components for lasting durability and compatibility with all vintage Rhodes pianos made between 1970-1984.

L.A. Custom Rhodes Preamp
Average rating:  
 11 reviews
 by Koen Van de Weyer

I really like the professional and responsive service. The unit arrived at my door within 5 days after ordering. And it sounds great! It really gives my Rgodes mark I 88 so much more dynamics in its tone. And it looks good too. 😊

Thanks, Koen! 5 days to Belgium is normal with DHL Express 🙂

Whoa!!! Just put it on the Rhodes and this thing does not disappoint. It brings out the highs that I wanted to capture. Thank you so much for this quality product.

I really like the fact there are still people like you so dedicated to making this kind of equipment for musicians. I received the preamp a few weeks ago, I'm really satisfied after a few weeks of working with it. I love the way it makes the Rhodes sounds more “tight“ and in balance.

The clarity and definition that I get with the L.A. Custom Preamp IS better than with the original preamp of my piano. I still use the original preamp when I want a more traditional sound. Having both is great! When I first took the L.A Custom Preamp to a gig, the upright bass player told me: "That sounds really good." The next night, a jazz guitarist said "I LIKE the sound of the sound of your piano..." They have both played with me before, and have heard the original preamp.

This preamp exceeded my expectations! Sounds wonderful!!

Smooth like butter sound. I had no idea what tone quality my Stage Rhodes MKII was missing until I plug this puppy in... thank you Nir Benjaminy! Its what we’ve all been waiting for.

Thanks, appreciate your kind words!

 by Jay Juniel

I’ve been using and enjoying the preamp. Definitely a clearer and more articulate sound. With the treble in the lower range, I can find a tone that’s softer and still reasonably defined. I may want to grab another unit.

 by Andrew Margolin

An ENORMOUS improvement to my passive Stage piano. The tremolo is awesome, too. Thanks for making this. Great sounding preamp.

 by Benjamin Bove

You don’t really know the potential of your Rhodes sound until this preamp unlocks its true potential. If you’ve got a Rhodes that’s “muddy” or you’re just not happy with the sound, I can guarantee you’ll be blown away with what you can do with this preamp. The EQ boosts hit dead on to the sweet spots in a Rhodes, the noise floor is dead quiet, and the build quality is hefty and substantial. You cannot be disappointed.

Thanks, Ben! We appreciate your continued support.

I've been seeking this sound for years. Works really well with my 1973 Stage connected directly to my sound card. It's like a screen has been lifted and the Rhodes sounds like Steely Dan records. Nice packing and fast delivery. The only downside is I can't stop playing the Rhodes now 🙂

 by Peter Arnold

I have been using this beauty with my 1970 Mark 1 Suitcase for three weeks now and couldn't be happier. No bells and whistles, just pure sound. It brings out all the gorgeous overtones and makes the sound come to life. If you have a Stage piano without active pre and tremolo you definitely need this. Suitcase owners like me will benefit from a new "open" sound, very different than the original preamp that's built into piano!

This is a remarkable achievement that every Rhodes lover should own.
