LS Effects The Boost Box II


LS Effects

The Boost Box II is a brand new Ultra Clean, class-A gain stage, Boost Pedal from LS. At the heart of the BOOST BOX II is a class-A MOSFET transistor that gives you over 30dB of clean transparent boost! The BOOST BOX II will give your amp a real kick when playing clean sounds and also with distortion sounds - you may never switch it off. Perfect for boosting your amplifier sound without loosing or changing its natural characteristics. The BOOST BOX II can be used as the first effect in your chain or last effect, and anywhere in depends on what you want to do. If you want to push your distortion pedal (for more distortion) or other pedals harder (great for many chorus and other time-based modulation effects), then use the BOOST BOX II right before those effects. If you want to have the same sound only louder or with some tube amp break-up, then use it as the last effect in your setup. The BOOST BOX II also has a ‘grit' switch. Flip this switch up to ‘grit' and the BOOST BOX II goes from ultra clean, to a fat, harmonically rich overdriven tone booster. This function allows you to have a cutting boost with a bit of gain. Not quite an overdrive, it just adds overdriven tube grit and edge to your tone. You can keep the BOOST BOX II on all the time to push your amp harder, or as an occasional boost to cut through the mix.
