The Dolamo D-1 Compressor is a compact analog compressor pedal for guitar, described by its maker as "a reliable and versatile compressor"1. It is based on the Dyna Compressor design, a circuit with a long history in compressor pedals, and it is a rehoused version of the Caline Hot Mushroom effects pedal, meaning the same circuit in a different enclosure under the Dolamo name1.
Controls and what they do
The D-1 keeps things simple with two controls:
| Control | What it does |
|---|---|
| Level | Sets the output volume of the compressed signal |
| Compression | Sets the amount of compression, with what RockBoard's PedalPedia calls "a wide range of compression options"1 |
RockBoard's PedalPedia describes the result in these terms: "Adding this pedal to your setup will result in a tight, well-defined signal and an overall richness to your sound"1.
Power
The D-1 is specified for 6V DC, center negative1, which is lower than the 9V that most pedalboard power supplies provide. Players will want a supply with a 6V output rather than a standard 9V outlet.
The pedal draws 30mA1, a modest figure that even a single 6V outlet on an isolated supply can handle comfortably.

Questions
What voltage does the Dolamo D-1 Compressor need?
The D-1 runs on 6V DC with a center negative plug, according to the pedal's listing on RockBoard's PedalPedia. That is a lower voltage than the 9V supply most pedalboards are wired around, so players should make sure their isolated supply can deliver a 6V output rather than plugging the pedal into a standard 9V outlet.
Can the Dolamo D-1 run on a 9V adapter?
The listed power requirement is 6V DC center negative, not 9V. Since many pedalboard power supplies only offer 9V outlets, players will want a supply with a 6V output for this pedal. Check the specifications on your power supply before connecting it.
Is the Dolamo D-1 Compressor analog?
Yes. The pedal's circuit type is given as analog, and it is described as being based on the trusted Dyna Compressor design, a classic compressor circuit.
Is the Dolamo D-1 the same as the Caline Hot Mushroom?
The D-1 is described as a rehoused version of the Caline Hot Mushroom effects pedal, meaning the same circuit in a different enclosure under the Dolamo name.
How much current does the Dolamo D-1 draw?
The D-1 draws 30mA, according to its listing on RockBoard's PedalPedia. That is a modest draw well within the capacity of most pedalboard power supply outputs.
