Synergy Amps has introduced the next generation of its Soldano SLO module — the SLO II all-tube preamp module. The original SLO pre-amp captured the Super Lead Overdrive sound and quickly became the most sought-after module in the Synergy community. The new SLO II offers three upgrades to the original module design. The SLO II offers a dedicated three band EQ on both channels, letting users precisely adjust each one independently. Also, the SLO II module now features a Crunch/Overdrive select switch per channel. This lets the player choice either of the Soldano gain options.
