The Dynobrain is based on the preamp circuit of a 70's Roland RE-301 Space Echo . I'm using a Fender Custom Shop Relic Tele and a Baroni Lab Blues 60 amp.

"In the fall of 2008, I built the very first replica preamp of the long defunct, vintage Roland RE-301 Space Echo from the late 70's. A life long pursuit of Brian Setzer's tone led me to the vintage space echo that he used between his guitar and amplifier.(name referenced for educational research purposes only). While that classic neo rockabilly and swing sound peaked my desire to create a small portable version of the Space Echo, I also want this dynamic preamp pedal to better let you hear your fingers on the fretboard w clarity and command a faster and fuller sonic response from your amp, at real world club and studio levels. This preamp provides a high fidelity catalyst between a wide range of guitars and amplifiers for a multitude of instrumentalist and styles of music. This is The DYNOBRAIN Preamp pedal for your Electric Guitar. I build my effect pedals for the best sonic relevance to bridges modern convenience w vintage aural authenticity.
For your Electric Guitar, I've replicated a much improved Vintage Japanese 70's preamp from the RE-301 Tape Delay machine known as the Space Echo. A Full sonic spectrum, preamplifier that is hand wired & loaded with hi-fidelity audio components; 22 gauge bonded copper strand wiring,, vishay metal film resistors in the audio path, socketed Opamp, Metal Film cap, Quality Sprague, Panasonic Electrolytics, etc w/ all flying leads to Alpha pots and switchcraft jacks w/ hardwire true bypass.

We've Improved the input impedence, extended the gain range & added a Bass cut that the original RE-301 didnt have, this aids in use with cranked small amp to keep the speaker from farting out AND when the Bass Cut is dialed back to 7 oclock, the tone sweep will give you a leaner, tighter modern flavor. Dial it back to 4-5 o'clock for the vintage full low mids of the original character and color. a "vintage-modern" contour if you will.

Worth a mention: The original Toshiba linear Op Amp was not magic, only special feature at that time was that is was low noise for 70's standards, but moving to a more modern version of this single opamp in the 8dip format, you will get less noise, and wider bandwidth and less distortion at higher saturation points. The option for the original NOS chip is available, but the right way to go to my experienced ear and thousands who use the Brain Preamp in pedalboards around the globe, is the modern chip I use in this preamp. Sounds kind of haughty, but thats not why I'm pointing it out. I simply want to make sure you realize you are getting the best version of this vintage Japanese preamp found in an RE-301 space echo.

My pedals are Loaded with the best Hi Fidelity audio components; silver mica and metal film caps, vishay & xicon metal film resistors in the audio path, panasonic & sprague electrolytics, 22 gauge bonded copper strand wiring to circuit board, socketed Opamp, w/ all flying leads to Alpha pots and Switchcraft jacks plus HD stomp switch hardwired, true bypass. Topmount jacks for the smallest footprint on your pedal board for this size box.

These components are upgraded from the original generic parts you will find in the vintage RE-301 space echo, that were very noisy. The original RE-301 was actually much quieter, w greater headroom than its predecessor the RE-201 that used random non spec carbon film resistors and transistors. So w our replication of the RE-301 space echo preamp, you are getting a much quieter version. If you want the option of the NOS Toshiba linear chip, please see the Dynobrain BS-301. No different, just vintage snobbier. :) All our preamps operate at 9v and 12v. I prefer to run mine at 9v for more texture and saturation at max gain.

Please allow 9 weeks for us to build your pedal for you, These are all built per order one at a time by myself and my son.
