The Valeton Dapper MDR is a combined effects unit that puts modulation, delay and reverb together in one all-in-one mini effects strip. Valeton describes it as "your ambient station," a pedal aimed at players who want those three time-based effect types on a small board without separate enclosures1.
Valeton lists the Dapper MDR as discontinued on its product page. The user manual remains available in the download section of that page1.
What it does
The Dapper MDR groups three effect modules on one strip: modulation, delay and reverb. For the modulation section, Valeton says to "use the two 3-way toggles to pick an effect you like best," giving six selectable modulation options across the two toggles1. The delay and reverb modules each have their own ON/OFF switches, and those switches do double duty: holding both at the same time enables the TUNER module, which mutes the unit while it is active so you can tune quietly between songs1.
For quiet playing, the PHONES jack accepts earphones. Valeton's line is "Plug your earphones into the PHONES jack for silent jams," which makes the unit usable without an amp in an apartment or late-night setting1.
Power and specifications
The Dapper MDR runs on a 9V DC center negative supply and draws 150mA of current. Its input impedance is 1MΩ, the standard high-impedance input for connecting a guitar directly1.

Where it sits in Valeton's range
The Dapper MDR belongs to Valeton's Dapper family of mini effects strips, which also includes the Dapper Mini, Dapper Dark Mini, Dapper Indie, Dapper Acoustic Mini, Dapper Looper Mini and the full-size Dapper. Each strip pairs a different set of effect blocks; the MDR's combination is specifically modulation, delay and reverb1. Players looking for a current-production Valeton multi-effects unit in a small format can look at the GP-5 or the wider multi-effects pedals range.

Questions
Is the Valeton Dapper MDR discontinued?
Yes. Valeton lists the Dapper MDR as discontinued on its product page, so the unit is no longer in current production. The company still provides the user manual in the download section of the product page, which is useful if you are picking one up secondhand or already own one and need the documentation.
What power supply does the Valeton Dapper MDR need?
The Dapper MDR runs on a 9V DC center negative supply and draws 150mA of current. Because of that current draw, it needs a supply rated to deliver at least 150mA rather than a low-output outlet meant for simple analog pedals.
Does the Valeton Dapper MDR have a built-in tuner?
Yes. The Dapper MDR has a TUNER module that you activate by holding both the DELAY and REVERB module ON/OFF switches at the same time. When the tuner is active, the unit mutes its output so you can tune silently.
Does the Valeton Dapper MDR have a headphone jack?
Yes. The Dapper MDR has a PHONES jack, and Valeton describes plugging your earphones into it for silent jams, so you can play without an amplifier in the room.
How big is the Valeton Dapper MDR?
Valeton lists the Dapper MDR at 197mm wide, 65mm deep and 42mm high, with a weight of 417g. That compact footprint is what puts it in the mini effects strip category.
