i understand james brown will do mods to his pedals. anyone know what kind of mods are available for the tightmetalpro? has anyone ever got him to mod their amptweaker pedals? id love to get a resonance knob or switch added like on the 6505 amps to give it that beefy thumpy bottom end. the low tone knob on the tightmetalpro seems to be more of a low mids knob. something to boost the 100hz area would be cool!
