The SECRET PREAMP™ is a GEM! It is definitely an Always-On type of effect. It really OPENS the sound of my DUMBLE amps! – Karl

What started as a love affair with the [Builder Name Removed 1], and went through various pedals including the [Builder Name Removed 2], has finally concluded with the SECRET PREAMP™. My search for an EP style “always on” pedal is done. I just could not be happier. I am just so happy with it, thanks and best of luck on everything else you do!

Absolutely Guaranteed.




“Vintage-Accurate, 1970s Solid State Maestro Echoplex Preamp with ‘Bright’ early EP3, ‘Dark’ later EP3 and ‘MID’ hybrid-capture EQ… Ideal at unity gain or slight boost with increased harmonic complexity and touch sensitivity.”

“Kyle Chase is possibly the world’s most OCD builder of new-old-stock amps and effects. When it comes to hardcore authenticity in vintage gear replicas, no one tops Chase Tone™.” – Premier Guitar Magazine

Possibly the most faithful [early and late 1970s] Echoplex preamp circuit reproduction in a pedal– sweetens your tone, adding complex harmonics and touch sensitivity. Chase Tone™ nailed this effect.”  – Collectible Guitar Magazine

“These features add up for a truly realistic EP-3 preamp feel and sound that is unlikely to be matched by similar designs.” -Tone Report Magazine


THE ORIGINAL 3D Tone Enhanced Bypass and Vintage Boost Pedal. ONLY FROM CHASE TONE™!

New Cool 70s Retro ROADSTER™ Box Style with Rear Mount Jacks takes half the pedal board space in comparison to our previous side jack bigger box versions.


The cosmetics, jack location and size I think they are a major improvement. Honestly, I think you knocked it out of the park. WAY ABOVE par [other brands] in terms of tone and performance. -Alec

Just wanted to drop you a line about the SP. Been using it for the last couple of months both before and after a variety of analog pedals and it delivers the goods every time. Tames high-gain fuzzes, sweetens BBD chorus and delays, analog phasors, and any kind of analog filter I have put behind it. The SP is an “always on” device in my rig. My core sound is clean Strat and the SP provides boost and sparkle without becoming brittle or sterile. Highly recommended!!! -Craig


A little history… In the 1960s and 1970s, Echoplex tape echo delay units evolved from tube based designs into solid-state designs. Notably, the EP3 model was a solid-state model and had a few variations and revisions to the circuit. A select number of EP-3 models are highly sought after by musicians for their unique musical tone.

This thing is awesome man. A lot of preamp or boost pedals push the amp in a way that makes them feel more like they’re overloading the amp rather than enhancing it. This secret preamp enhances everything before and after it! It’s really killer man. Still need to check it out a few other ways but so far its fantastic. -Matt

Famous musicians of the era and later realized having the EP-3 in their signal altered their tone, even when the echo was bypassed. An internal secret preamp was at work here, boosting and fattening the signal, along with a slight phase shift that alters mid and high frequency harmonic content providing a transparent warm boost – a truly secret preamp boost in the arsenal of the great guitarists of yesteryear!

Hey Kyle, the eagle has landed! Nice job. Looks great, soldering is tidy and the tones are what I sought. I used it with and without a DM-2 and the Secret Preamp™ was a great addition to an already great sound. – Rik

But not all vintage EP-3s boosted, some dropped in signal due to the wrong TIS58 JFETs, and some were mediocre in tone being a different circuit revision. So, over a decade ago I did something about it! The Chase Tone Secret Preamp™ Effects Pedal uses fine-tuned circuit components to ensure proper results. It is currently the only authentic replica of the most sought-after, musically transparent signal-boosting Echoplex units.

Excellent Clean Build! Nailed my actual EP3 tone to a tee! -Mark

If you have a half decent setup, this box will give you a boost that will make your amp work just a bit harder, sound just a bit sweeter and help you play a little better. Improved headroom, both in terms of volume and spectrum. Somewhere to go when you dig into the strings. – Steve

“Blown away- this is the real deal. Great product!” -Barrett

The pedal is great, everything I’d hoped for and love the mini toggle on the side for different options. Can certainly achieve a lovely fat boost or just enhance whatever sound you already have, will be gigging it at the weekend! – Robert


Applications: The SP™ is BEST placed LAST in the signal chain.

  1. The Secret Preamp™ provides a slight boost to a tube amplifier and you’re in complete control of the EQ for different rigs and rooms!

Preamp pedal is incredible. Truly outstanding pedal. Such a rich, alive sound. Makes the strings very touch sensitive. I love it. Thank you! – Hyram

I played last night with the preamp and it sounded amazing…I love it !! I can’t believe that I waited so long to try it out. It makes everything sound so much better with so much more character to the sound…and the way how it feels too, very touch sensitive, just great !! – Diego

Kyle your Secret Preamp™ is just fantastic. Sweet boost, super quiet even at max and the toggle is really nice option. I now just have the Secret Preamp™ and my Effectrode fire Bottle for all my boosting. Congrats on a great product. Gene

I haven’t stopped using it. Sounds really great as a slight boost through my Soldano SLO, great pedal. Thank you very much. -Ben

  1. The Secret Preamp™ can be used as 3D Tone Enhanced Bypass for overloaded true bypass pedal boards. (The industry standard of buffering can ruin the dynamics and feel and sound shrill.) The Secret Preamp™ IMPROVES tone and signal response over just plugging in a single guitar cable to your amplifier.

Sounds brilliant. Very difficult to explain how, but just better. More 3d. More alive. More vibrant. Not played around too much yet but seems, already, quite indispensable. Fantastic customer service. Fantastic product. – Rob

  1. Customers love placing the Secret Preamp™ before or after [experiment] an analog delay pedal to bring vintage Echoplex tone to the signal-no need to lug that big and often unreliable/noisy Echoplex around just to have it alter the tone!

I prefer the up position and the beautiful way that it just enhances everything. Brilliant job. I will definitely be considering some of your other products in the near future. All the best, Martin.

  1. Engaging the Secret Preamp™ after a vintage Fuzz will replicate the “cranked tube amp combined with Fuzz” tones – without cranking the tube amplifier!

“I wanted to thank you for the secret preamp you built. This pedal does the preamp better than any other box I’ve used. It may even sound better than my Echoplex. Glad I went out on a limb to find you. I’ll be using this to capture the tone in my head for some time to come. Thanks for your work and passion. Sincerely, Jordan

“One of the best tone builders! Excellent person, very friendly. Simply the BEST!” –Juan (Cabo Wabo)

Hi Kyle, I must say it sounds wonderfull in both DARK and BRIGHT settings. On my Dr Z Z-Lux, I may prefer the DARK setting, at least with bright guitars such as Strats or Teles. It sounds good by itself indeed, but it’s actually stacked with other effects that this preamp really shines to my ears. My overdrive and fuzz pedals have never sounded so BIG, full and as detailed before. I’m impressed. Thank you. Regards, Romain


Jim Weider

Hello Kyle, I got the Secret Preamp™ today and used it at rehearsal. In an A/B it’s very close! You’re the only one and I’ll let people know you got this so close without ever hearing my Echoplex. So far this is the closest. Good ears!! -Jim Weider. Update: I’ve been using it on all shows, just leave it on all the time!

Recent Customer Feedback:

Hi there! Just wanted to write back and tell you guys that this pedal is amazing. It has been the “glue” to my entire rig. I don’t use much, I have a small pedalboard, just one guitar, just one amp. But I’m picky about the sound I get from my few pedals (5 pedals). And let me tell you…I place the preamp (always on) after my 2 overdrives which I stack for leads, and it just gives me more punch while providing articulation.  As if it’s “cleaning” up all the “unnecessary”, and just allowing the “quality” saturation come through…I don’t even know how to describe it, point is it just works beautifully. Thank you, Jaime

I just received my secret pre amp and it really rocks, brings tone to life, adds harmonics, specially if you use a good amount of pedals (that will gradually suck your tone). It´s gonna be an always on type of pedal for sure. Amazing stuff!!! – Joao

Hi Kyle, Just wanted to say that I am absolutely in awe at the sound I’m getting with this Secret Preamp™. My original Fulltone 69 fuzz pedal is one of those love it or hate it pedals and as much as I like the sound of fuzz, I always struggled with finding that sweet spot with my rig. After running it through the Secret Preamp™, it sounded fuller, livelier and totally tamed that harsh hairiness of the fuzz. And this is just through my practice amp. I’m really excited to try it through my main amp (AC30) and with other pedals. It has gotten me to fall in love with the fuzz again. Thanks again for building an awesome pedal and can’t wait to incorporate it into my new board. -Thanks! John

Good morning, Kyle. The Secret Preamp™ is giving me a cleaner sound with more crunch. I need to redo all of my pedal board I have some stuff that I won’t need anymore. Now I would like to order the Silicon Fuzz! – Thanks again, Bernie

The Secret Preamp™ arrived today. The beauty of the Secret Preamp™ is its simplicity; it simply makes everything else sound better! Especially delays and fuzzes. Between the service and the product I am very interested the Scripture Wah™ now! – John

Thank you so much for my brand new Chase Tone Secret Preamp pedal (this being my 4th from you – yes, 4 LOL.)  This pedal is pure magic and works great for keyboards , Moogs and Bass as well! What is does to my Pure Sixty Four Tweed Deluxe and Tweed Twin is nothing short of astonishing. All the rich gooey elastic clean tones just ring through with an authentic vintage vibe that places me in that musical pocket of Tone, that pleases me so very much!- John

Kyle, I did use the pedal [on Saturday’s gig] and really liked it.  Definitely made my amp sound more ‘alive’.  Train’s sound man does our sound and came up to me after the first set and commented on how good my tone was that night. Thanks for everything!  It has been a pleasure dealing with you.  You delivered a great pedal and top notch customer service. -Mike

“The REAL deal – have no doubt – this pedal IS IT.”

 “Item arrived very quickly. Beautiful pedal, high quality build, amazing tone!”

I got the Secret preamp yesterday, amazing tone man! You really nailed it.

I think I’m never gonna turn it off, I just love what it does with my overall tone – specially with my strats. Great job man, thanks! – Steven

Hey Kyle…Just wanted to rave about the secret tone pedal I have …I Totally love it and cannot live without it in my rig….GREAT JOB…. – Patrick

I have to say that I really like what it does for my tone.  My cleans have never sounded better.  Definitely a keeper.  Highest compliments to you on the design, build, and implementation!  – Art

Great transaction! Everything was superb! Item exceeds description. Great Ebayer

As described, Super fast shipping, Very helpful, Would buy from again, Thanks

“I’ve said it before, but I’ll say it again, your EP3 pedal is incredible. I’ve had the < name removed 1>, < name removed 2>, <name removed 3> and the <name removed 4>.  Yours is the most usable and clear. Not too much low end and not too shrill with the highs. And the volume pot is very usable depending on the guitar. Good luck with all your pedals. I hope your business really takes off! Thanks again” – Paul

 “I got your wonderful pedal and yes it’s pretty freaking amazing. I much prefer it in the upper EP3 position, which seems to enhance the overall string tone, seeming more on the treble side, yet still full body, if that makes any sense.  Just sounds amazing. . . can’t find the right words to express the sound but I’m totally digging it” – Mel

“Hey Kyle, the pedal arrived…I love it!!! My twin reverb has never sounded better.I have many hours of fine tweaking ahead. Congratulations, this is even better than you claim. Wah pedal next.” – SteveAwesome pedal and seller, great communication, thank you !!! – Yann

Amazing pedal- thank youwhat a great pedal!

thanx-a-zillion, this is the problem-solver for any ep3-user!

I’ve long been a fan of the Ep-3… It really is EVERY SINGLE BITas good as the pre on my current (and favorite) ep-3. And that’s what I want – but in a pedal. Nobody else’s  (and I’ve either owned or tried them all) come close to yours in terms of the authenticity of what the circuit does to the guitar’ssignal. (They’re not bad, don’t get me wrong.) Your secret pre is perfect and has afull time spot on my board. Thanks man! – Sin
