The Iron Horse LM308 V3 Halloween 2023 Limited Edition is a limited edition version of the Iron Horse distortion and fuzz pedal from Walrus Audio. It is an analog circuit, listed by RockBoard's PedalPedia as covering distortion and fuzz territory, and it carries the Halloween 2023 limited edition treatment on the standard V3 platform1.
Key facts
Power and setup
The pedal runs on 9V DC with a center negative plug and draws 10 mA, so it sits comfortably on a standard pedalboard power supply alongside typical drive pedals1.
As with most compact drive pedals, plan for a dedicated 9V DC center negative output from your power supply rather than a battery.
Where it sits in the Iron Horse range
The Iron Horse LM308 runs on 9V DC center negative power and draws 10mA1. Walrus Audio has issued the Iron Horse in several versions over the years, and the Halloween 2023 Limited Edition is one of those variants of the same distortion platform.
