The ASD-1 is the first pedal in our Analog Spring Driver pedal series. With the ASD-1 you can add real spring reverb to your pedal board. Just insert this pedal into your effect chain and connect a spring reverb tank to the RCA jacks on the side of this pedal. The internal circuitry of the ASD-1 drives the springs of your reverb tank for an authentic spring reverb effect. While there definitely is some tonal overlap with some of the classic reverb units, the ASD series is not another Fender circuit clone. In addition to being able to produce classic reverb tones, the controls on the ASD allow you to push the parameters well beyond what the classic units offer. This pedal will produce anything from a very mild reverb, all the way up to a hard overdriven spring reverb. Additionally, the is no wet/dry level blend control. Instead, wet and dry signals are independently controlled so you can run your instrument entirely through the springs if you want. Or you can turn the springs off and turn the dry level up for a clean boost effect. If you want both unique and classic real spring reverb sounds, this is the pedal for you.
This pedal can be powered by a standard Boss-style 2.1 mm 9V negative-center power cord only. Spring tank and RCA cable are not included. See the ASD Product Manual for recommended spring tank specifications. For answered to frequently asked questions read the Analog Spring Driver FAQ.
Purchase the Mod® 8EB3C1B, Long Decay, 3-Spring Tank with RCA Connector Cable so you have everything you need for your reverb effect.
Be sure to check out the ASD-2 which has an internal spring tank included!









David Hodges –
I have 3 of the ASD-1 Reverb Drivers and they are fantastic quality, tone and build.
These aren’t just another Fender reverb tone. To my ears the ASD-1 has a much warmer tone than a typical Fender style reverb. They have taken the place of my SurfyBear reverbs.
These also boast unique eq and controls when comparing to other reverbs out there.
I use these in front of the amp and I also use them in the effects loop depending on the setup I’m using at that time.
I sometimes love to run the
ASD-1 with a brighter reverb and level them out for lots of depth that nothing else can get close to.
This doesn’t get the typical surf drip but it gets it’s own, unique flavor of reverb that honestly just works and sounds AWESOME.
It can go from subtle “room” level setting all the way to “outerspace”.
You can also use it to give you a really transparent, clean boost if wanted.
I also love the fact that it can easily fit on a pedalboard and that I can use a large array of different reverb tanks with it.
I simply put the pedal on a pedalboard and have my reverb tanks mounted on a 19″ piece of wood with the rca cables running to it.
This works great and doesn’t take up a massive chunk of my pedalboard like my SurfyBear pedals do.
The ASD-1 takes up about half the space that even a surfybear compact takes up and has way better tones for me.
Anyways, I highly recommend the ASD-1 and wouldn’t hesitate to get one as soon as you can.
Top notch quality!
My go to reverb!!!
