Check the listing for details. Orange Amplifiers Two-Stroke Boost EQ Guitar Effects Pedal. Condition: New. Listed at 149.00 USD. The Two Stroke Boost EQ is Orange's take on the essential ‘clean boost’ pedal, but with even more versatility. Combining an active dual-parametric EQ and up to 12 dB of output boost, the Two Stroke is the perfect tool for fine-tuning your sound or pushing your amp’s front end with unsurpassed control. Subtle Two Stroke tweaks can add an extra dimension to solos, whilst more aggressive use of the pedal’s EQ can sculpt entirely new sounds. Use the Two Stroke to add an extra channel to your amplifier or re-voice your guitar’s pickups completely. Crank the high mids to jump through the mix, cut the low end to remove the woolliness that normally occurs with traditional boost pedals, or leave the EQ flat to hear more of what you already like.
