The Mad Professor Silver Spring Reverb is an analog reverb pedal made in Finland by Mad Professor, designed to add reverb to your dry sound through a single Reverb knob1. Delicious Audio describes it as an "analog unit designed to offer an extremely natural-sounding Reverb that enhances the tone of your rig"2.
What it does
The Silver Spring Reverb adds reverb to your dry signal, with the amount set by the Reverb knob1. As an analog unit, it sits among the minority of reverb pedals that avoid digital processing entirely; Delicious Audio characterizes its design goal as an extremely natural-sounding reverb that enhances the tone of the rig rather than washing over it2.
It connects with a standard input and standard output, so it drops into a normal signal chain without special cabling1. With one knob and no menus, there is nothing to program: you set the reverb level with your ear and play.
A point that matters to players running gain: Delicious Audio notes it "works well with distorted and overdriven tones"2. Reverb placed after overdrive or distortion can turn muddy on some pedals, so a reverb that holds together with driven signals is a practical distinction. Players who keep their reverb at the end of the board and push it with gain pedals will not need to reorder the chain to suit this one.
How it is controlled and powered
The control surface is a single Reverb knob, which Guitar World's reviewer, Trevor Curwen, found easy to use1. There are no mode switches, no presets and no secondary functions to learn, which keeps the pedal simple for a beginner and quick to dial in on stage.
Power comes from either a 9V battery or a 9V DC adapter, with a current draw of 80mA1. The battery option means the pedal can run without a power supply at all, while the adapter figure is the one to check against a small daisy-chain supply, since 80mA is more than a typical analog drive pedal draws.
The pedal is true bypass1, so when it is switched off its circuit is out of the signal path entirely, rather than buffered and colored.
What reviewers said
Guitar World's review praised the pedal's sound quality and compact size, with Curwen calling it easy to use with a simple control surface1.
"Easy to use with a simple control surface."
Delicious Audio's writeup echoed the design intent, describing an analog unit built for an extremely natural-sounding reverb that enhances the tone of the rig, and noting that it works well with distorted and overdriven tones2. Together the two reviews point the same way: a small, simple, analog reverb that favors natural tone over features.

Questions
Is the Mad Professor Silver Spring Reverb analog?
Yes. The Silver Spring Reverb is an analog unit, described by Delicious Audio as designed to offer an extremely natural-sounding reverb that enhances the tone of your rig. That makes it a straightforward choice for players who want reverb without a digital conversion of the dry signal.
Does the Silver Spring Reverb run on a battery?
Yes. Guitar World lists its power as a 9V battery or a 9V DC adapter, so it works on a pedalboard power supply or on its own battery. Current draw is 80mA, which is worth noting when planning a power supply.
How much current does the Silver Spring Reverb draw?
Guitar World lists the current draw at 80mA from a 9V DC adapter. That is modest by modern standards, but it is more than a typical analog drive pedal, so it is worth checking against a small daisy-chain supply.
Is the Silver Spring Reverb true bypass?
Yes. Guitar World's review lists true bypass among its features, so the pedal's circuit is out of the signal path when it is switched off.
Does the Silver Spring Reverb work with overdrive?
Yes. Delicious Audio notes that it works well with distorted and overdriven tones, which is not something every reverb pedal can claim. Players who run gain into their reverb will not need to change their signal order to suit it.
