A Timeless Classic Reborn Experience the dreamy sound of a classic ‘60s tape echo complete with the harmonic richness of the accompanying tube preamp.

Enjoy organic and ethereal modulation produced by countless subtle mechanical imperfections, and easily dial in anything from warm slapback to expansive echo feedback beds with a strikingly gorgeous stereo image.

With beautifully-tuned low frequency response, lush tape saturation and sublime echo decay, EC-1 provides all the best of what a tube driven tape echo can deliver.

Tape, Tubes, and the Best of the Best
 Development of EC-1 started with the groundbreaking single moving head algorithm originally developed for our El Capistan pedal, which is renowned for its lifelike reproduction of vintage tape echo.

From there, we were fortunate to acquire what turned out to be a very special Echoplex EP-2, as the unit was in amazingly good condition and had been worked on by storied technician Cesar Diaz. We discovered that several purposeful and skillfully-implemented modifications had been made to the unit, including tweaks to the tube preamp for a warmer sound closer in frequency response to an EP-3. The modifications seemed aimed at bringing the best aspects of the various vintage Echoplex models into a single unit, and the inspiring result significantly informed development of EC-1, imbuing it with a special character that is immediately nostalgic.

Full-Featured Compact Stereo Tape Echo
 EC-1 offers impressive power and flexibility in a small and elegant form factor.

Selectable tube-modeled preamp voices. Artifact-free tap tempo. Discrete stereo operation for independent processing of the left and right stereo inputs. Straightforward controls and expression pedal capability. High-impedance, ultra-low noise discrete Class A JFET stereo input preamp for exceptional touch sensitivity, dynamics and feel. MIDI control of tempo, patch save/recall and more. Premium components, rugged construction and a USB jack for performing firmware updates or controlling the pedal from a computer.

This Victoria 45410 is our loving recreation of the '59 Bassman and no detail is left undone. Our Victoria capacitors were designed specifically to sound like a slightly degraded, 40 year-old cap. If you've ever wondered why expensive new 'reissue' amps often sound cold and chiseled compared to their vintage counterparts, now you know. The 45410 is a complex, detailed, and dynamic amplifier that responds to pick attack like no other amp on the planet. It's also a rock solid bass amp for recording and club work.

• 45 watts of power • 5F6-A Type Circuit • Class A/B Adjustable Fixed Bias • Push/Pull Operation • Standard Speakers: Four American Made 10" Eminence • Standard Covering: Tweed • Tubes: 1-GZ34, 2-5881, 2-12AX7, 1-12AY7 • Cabinet Size(HxWxD): 23.5” x 24” x 10.5” • Weight: 48 lbs.

A lot has changed since Jon Black­stone first offered his “Mosfet Overdrive” circuit as a pedal in 1998. Yet here in 2025, with all the boutique amps, emulators and pedals available, many guitarists continue to rely on it as their go-to dirt box.

People that bond with the Black­stone Mosfet Overdrive are probably looking for the same thing Jon was during the decades he was modding tube amps – harmonics that seem integral to the tone, not a fizz that sits on top of it.

The pedals Jon is cur­rent­ly building are the same ones he's been making for 20 years or so. Two “channels” (foot­switch­able presets), in an MXR-sized pedal with unique recessed controls. They're sold here on this website, not on Reverb or Amazon.

While most overdrive pedals create distortion with a pair of head-to-toe diodes, the Blackstone instead employs four gain stages, each con­tributing a small amount of soft clipping. That avoids intermodula­tion and the creation of fizzy high-order harmonics, just as in the best vintage amps. Those amps sound good in large part because the distor­tion does not occur at just one point.

The cir­cuit is also un­usual in that it interacts with the induc­tance of your guitar's pickups to get its unique dynamic response. Because the guitar's pickups and controls are actually part of the input stage, you can go from a juicy lead sound to a barely-breaking twang with just the guitar's volume control.

The Mosfet Over­drive gets its distor­tion entirely on its own – it is not a "boost" pedal meant to cause distortion in your amp. It does its thing into pretty much any amp, at any volume.

3 WAYS IN WHICH THE BLACKSTONE IS DIFFERENT: The character changes as the gain increases. It's glassy at low settings, becoming fat and midrangey when cranked. This is the opposite behavior of most pedals, which get thinner and fizzier at high settings. And this makes it versatile, ranging smoothly from very subtle to pretty heavy.

Control it from your guitar. Another area where the Blackstone stands out is in how you can control it with the volume control on your guitar. If you listen to the third clip on the sound clips page, you'll hear how most pedals just get a little brighter when the guitar volume is increased from 6 to 10, while the Blackstone runs the gamut from almost clean to a fully saturated sound. The Blackstone must be the first effect after the guitar to acheive this.*

OK, the controls are weird. It has slotted-shaft pots that are flush with the etched steel nameplate on the top of the pedal. They can be turned easily enough with your thumbnail, but they hold their settings when the pedal is stuffed into a gig bag. The EQ control is not a high cut, it's a post-distortion mid cut.

At higher drive settings, the Mosfet Overdrive is very sensitive to the differences between pickups. That's why the drive control for the "red" channel is divided into two ranges - one which causes single-coil pickups to sound fatter as maximum drive is approached, and one which tightens the bass when humbuckers or P-90s are used. In its standard mode, the circuit interacts with the guitar's pickups, and needs to be the first effect after the guitar. But there is now an internal switch that puts the pedal into "buffered" mode, permitting use after other effects, wireless systems and active pickups.

It's important to remember that recommendations you hear on overdrive pedals often stem from somebody getting a good sound out of a combination of a certain pedal with a certain amp, when a lot of the distortion was actually occurring in the amp. Again, the Blackstone is intended to get the distortion on its own, into whatever amp is suitable (or available!) for the gig you're playing.

Distorting the electric guitar is a very subjective thing. But if you're looking for a tone that's more juicy than fizzy – something that inspires expres­sive playing – you may want to check out the Blackstone.
