The golden combination of 60's Blackface and the legendary Screamer is reproduced at a high level! This is the perfect car for SRV and JM fans! As the name suggests, Crossfire is a 2-in-1 pedal that combines the sound of a vintage blackface US combo amp with the sound of the legendary Screamer overdrive pedal. The amp section on the left allows you to switch the headroom, which is affected by the power tubes and the installed speaker, as well as features such as a bright switch and tone control, accurately reproducing the sound of a Blackface amp. The overdrive section on the right recreates the low- and mid-range-focused sound of vintage green pedals. Other features include a MORE switch to increase gain and a symmetrical/asymmetrical clipping mode for more control. Between the two sections there is an insert jack, allowing you to connect other pedals of your choice between the overdrive section and the amp section, or use the SND/RTN jack to use the left and right sections as separate effects.
