JAM Pedals - Boomster mk.2


In Stock - Free Shipping Eligible

The JAM Pedals - Boomster mk.2 delivers up to 16db of clean, unadulterated boost to push the front of your amp. Here with 3 selectable voicing options, the Boomster is flexible enough to sculpt your tone and deliver the right sound for each guitar in your rig. The top position brings out the high-end sparkle, while the middle position is more of a flat, full-range response curve. The bottom position is more mid focused which can deliver some great 60s-breakup tones. The top and bottom positions both offer set-and-forget internal trim controls for dialing in just the right amount. Selectable as a true or buffered bypass via internal dip switches, the Boomster is a great boost/buffer solution for any pedalboard. Jam Pedals are hand-painted and vary slightly in appearance.

From Jam:
• Selectable true or buffered bypass via internal dip switches (see schematic)
• an expression pedal input to use as a volume pedal
• 3 minutely tuned voicing options
• momentary / latching operation
• 9-18V power-input range for variable headroom
• the top position attenuates the top end (control by how much via set-and-forget internal trimmer)
• the middle position retains a flat, full-range response
• the bottom position introduces more mids (control by how much via set-and-forget internal trimmer)

*When the Level knob is all the way to the left (closed) the Booster’s output level is at unity gain.
