The GAS (OD/CB) Guitar is an overdrive and clean boost pedal from Rodenberg, an analog design that puts two different sounds in one box: a top-level overdrive and a Clean Boost that can add up to +20dB of output. RockBoard's PedalPedia describes it as standing for "a natural, straightforward going overdrive tone without coloring" the original sound, and says it works in front of a clean, overdriven or distorted amplifier1.
What it does
The pedal combines two sections. The overdrive side is described by the maker as delivering top level overdrive sounds, and the Clean Boost side offers more output levels, up to +20dB, selected with a toggle switch. according to RockBoard's PedalPedia, the Clean Boost "brings new life into every ampli[fier]"1. As a two-in-one design, it sits in the territory covered by overdrive pedals and boost pedals, and players who only need the boost half of this kind of circuit may also look at the Rodenberg SL Clean Boost or the Rodenberg LDP.
Controls and toggle switches
The GAS (OD/CB) uses toggle switches to extend what each section can do1:
- Bass boost toggles: two separate bass boost toggle switches, one for each pedal section, so the overdrive and the Clean Boost can be shaped independently1
- Gain boost toggle: a gain boost switch on the overdrive section for higher-gain settings1
- Boost level toggle: a switch on the Clean Boost section that selects output levels up to +20dB1
Power
The pedal runs on 9V DC, center negative, and draws 50mA1. That is a standard supply format, but the 50mA draw is worth checking against the per-output rating of a shared supply or daisy chain before connecting it.
The maker's page does not list battery operation, so plan to power the pedal from a 9V DC center negative supply1.

Questions
Is the Rodenberg GAS (OD/CB) analog or digital?
It is an analog pedal. The maker's product page lists the circuit type as analog, meaning the signal is processed in the analog domain rather than converted to digital. Players who want to keep their signal path analog, or who prefer how analog overdrive and boost circuits respond to the guitar's volume control, will find that here.
What power supply does the Rodenberg GAS (OD/CB) need?
The pedal runs on a 9V DC supply with a center negative plug, the same standard used by most compact pedals. It draws 50mA of current, so a standard isolated supply output rated at 100mA or more will run it comfortably. The maker's page does not list battery operation, so plan on a power supply.
How much current does the Rodenberg GAS (OD/CB) draw?
The maker lists the current draw at 50mA. That is a modest figure by modern standards, but it is above what some very low-draw pedals need, so it is worth checking the per-output rating on a shared or daisy-chain supply before plugging in.
How much boost does the Clean Boost section give?
The Clean Boost section offers more output levels, up to +20dB, selected with a toggle switch. That is enough headroom to push an amp's front end harder or to lift a solo above a band, and the maker says it brings new life into every amplifier.
Can the Rodenberg GAS (OD/CB) be used in front of a clean or overdriven amp?
Yes. The maker describes the pedal as producing a natural, straightforward overdrive tone without coloring the original sound, and says it works in front of a clean, overdriven or distorted amplifier. That makes it usable whether you are pushing a clean amp into breakup or adding to gain that is already there.
