Oliver Hartmann is a guitarist whose name shows up in two makers' camps: he is on BluGuitar's artist roster as one of the artists who play BluGuitar1, and he is quoted by Nobels about the overdrive on his boards. For a player comparing rigs, the picture is a simple one: a BluGuitar connection on the amp side and a single overdrive pedal that he treats as a fixture.
The sound he is known for
The gear statement Hartmann is quoted on is the Nobels ODR-1, an overdrive pedal. Nobels quotes him in one line, and the line is specific about how central the pedal is to his setup:
"The only Overdrive you'll fi nd on all of my pedal-boards . . ."
That is a strong claim for a working guitarist to make. It does not mean the ODR-1 is the only drive effect he owns, but it does mean that wherever you find one of his pedalboards, an ODR-1 is on it, and no other overdrive is. For players who build boards around a single always-there drive stage, that is the same job the pedal fills for him.
Amps and other gear
On the amp side, Hartmann is named by BluGuitar among the artists who play the company's products1. BluGuitar's artist page does not go into which of its amps or pedals he uses, so the connection stands as a maker's roster listing rather than a rig detail.
Putting the two together, the rig is short:
- Overdrive: Nobels ODR-1, which he says is the only overdrive on all of his pedalboards2
- Amp maker: BluGuitar, which lists him among its artists1
Questions
Is Oliver Hartmann a BluGuitar artist?
Yes. BluGuitar names Oliver Hartmann among the artists who play BluGuitar on the company's artist page. Beyond that listing, the maker does not publish details of which BluGuitar products he uses, so no specific model can be named here.
