The Dolamo D-8 Overdrive is a compact analog overdrive pedal made by Dolamo. RockBoard's PedalPedia describes it as "an incredibly dynamic Overdrive guitar effect pedal which responds well to your picking strength," meaning it cleans up when you pick lightly and opens up as you dig in, the way a tube amp's front end does1.
Circuit and sound
RockBoard's PedalPedia lists the D-8 as influenced by the Xotic RC, a circuit known in overdrive circles for a relatively open, uncolored boost-and-drive character rather than a heavy midrange hump1. For a player, that places the D-8 on the transparent side of the overdrive family: it is closer in spirit to a boost-plus-drive than to a Tube Screamer-style mid-forward design. If you want harder clipping, the neighboring categories are distortion and fuzz.
Because the circuit is analog, the pedal handles your signal without digital conversion, which is the usual preference for a low-gain drive placed early in a signal chain1.
Power
The D-8 runs on 9V DC, center negative, and draws 30mA of current1. That is a light draw by pedal standards, so a standard 9V supply or an isolated output on a pedalboard power unit covers it.
The 9V DC center-negative requirement is the standard for compact pedals, but it means the D-8 needs a proper DC supply or adapter; it is not designed for AC or higher-voltage inputs.
Hearing it
RockBoard's PedalPedia listing includes a demo by Rudy Bressers in English, which shows the pedal's response to picking strength and where it sits tonally1.

Questions
What circuit is the Dolamo D-8 Overdrive based on?
The D-8 is influenced by the Xotic RC, according to the product listing on RockBoard's PedalPedia. That makes it a compact overdrive in the transparent, low-to-mid-gain style associated with that circuit, rather than a mid-humped design. Players who know the RC will find the D-8 follows the same general approach in a budget-friendly package.
Is the Dolamo D-8 analog or digital?
The D-8 Overdrive is an analog pedal. Its circuit type is listed as analog on the RockBoard PedalPedia product page, so it processes your guitar's signal with analog circuitry rather than digital conversion.
What power supply does the Dolamo D-8 use?
The D-8 runs on 9V DC with a center-negative plug and draws 30mA of current. A standard 9V pedal power supply or an isolated output on a pedalboard power supply will run it, and its modest current draw keeps it easy to fit into an existing setup.
Is there a demo video of the Dolamo D-8?
Yes. RockBoard's PedalPedia listing for the D-8 Overdrive includes a demo by Rudy Bressers in English, so you can hear the pedal's overdrive tones and how it responds to picking strength before deciding whether it suits your rig.
